Cycas (Cycas) - a perennial, tree-like, decorative and deciduous plant from the Sagovnikov family, relative of fern. The birthplace of cicas is tropical and subtropical regions of China, Japan and the Pacific islands. Tsikas has been growing in nature since ancient times of the Mesozoic era.
This cycad is similar in structure to a palm tree with its rigid, needle-shaped, cirrus leaves, located in the shape of a rosette at the top of a wide, massive trunk, covered with a dense rough bark. For this similarity, the plant is often called the sago palm.
The height of cicas in nature is up to 10 m, in offices and residential premises 50-70 cm, in greenhouses - up to 2 m. For a year it grows by 2-3 cm and one or two leaves, each of which can live 2-3 of the year. The root system has the shape of a bulb.
Be sure to pay attention to such a palm tree as Washington.
|Growth rate is low. For a year, it grows by 2-3 cm and one - two leaves.|
|Does not bloom.|
|The plant is difficult to grow.|
|It is a perennial plant.|
Tsikas prefers bright diffused light, with a certain amount of direct sun, it is suitable for growing at windows of the western and eastern directions, it can grow at the northern window. At the windows of the southern direction in the summer, it is recommended to shade the cicada from direct sunlight. In the summer, you can put the plant in the open air, in a place protected from the midday sun. Keep in mind that it is recommended to accustom the plant gradually to a new level of illumination.
The correct temperature regime is very important for cicasa. In the spring-summer period, plants prefer a moderately warm content (22-26 ° C). The optimum temperature in the autumn-winter period for Tsikas bent 10-12 ° C, for Tsikas curled slightly higher - 16-18 ℃. If the winter does not provide coolness to the cicasus, it is sick, and may lose some of the leaves.
The cicada is watered sparingly from spring to autumn, allowing the substrate to dry to a depth of 2 to 4 cm, depending on the size of the pot, but not allowing prolonged drying. In winter, they are watered even more moderately than at any other time; during this period, waterlogging is especially dangerous. Watering is carried out with soft, settled water at room temperature.
Tsikas prefers high humidity, it is recommended to spray it regularly with soft, settled water at room temperature. You can also place a pot with a plant on a pallet filled with wet expanded clay or peat. You can bathe the plant from time to time under a warm shower, just make sure that the water does not fall into the pot.
From spring to autumn, cicas is fed with mineral fertilizer for palm trees every two weeks. Starting in October, top dressing is reduced and carried out no more than once a month, and from the summer norm, the concentration of fertilizer is recommended to be halved. It is not recommended to use fertilizers with potassium and magnesium salts.
Tsikas has a pronounced dormant period in winter. Contain plants in a cool, bright place. The optimum winter temperature for Tsikas bent 10-12 ° C, for Tsikas curled slightly higher - 16-18 ℃. Water carefully.
Young specimens are transplanted annually, in adults it is enough to replace the top layer of the earth or transplant if the plant has become very crowded in a pot. For transplantation use a soil mixture similar to the "palm", i.e. a mixture of turf land, leaf, peat, humus and sand in a ratio of 2: 1: 1: 1: 1. The best time for transplanting is spring, before the start of new growth. At the bottom of the pot provide good drainage. Keep in mind that when choosing a pot, do not try to take a large container, try to keep the plant tight in the pot, otherwise the cicada may become ill due to acidification of the substrate.
Cycases are propagated by seed and branch of bulbous young shoots, sometimes developing on the trunks of adult specimens. Beginning its development with an air bulb, which is essentially a axillary bud, this shoot gradually acquires a normal crown, and sometimes adnexal roots.
Gardeners cause branching artificially, inflicting mechanical damage on it in order to obtain either a fancy dwarf form with several crowns or a large amount of planting material.
When separating the "baby" the place of the cut is sprinkled with crushed charcoal and dried for 1-2 days. "Children" are planted in a soil mixture of peat, sheet soil and sand with the addition of fine granite chips. Before the roots are watered very moderately.
Seeds retain viability for 2-3 years, germinate rapidly 1.5-2 months after sowing.
From direct sunlight, especially in the summer, the plant can get a sunburn, they should be accustomed to cicada gradually.
The plant is prone to rapid decay due to overflow and acidification of the substrate. Particular sensitivity to overflows is a characteristic feature of cicasses.
Tsikas suffers from high winter temperatures and dry air, and can drop leaves under such conditions.

Cycas revolving in culture
This type of cypress is the only one that can tolerate small frosts, so it is known far beyond its natural range. On the territory of Russia and neighboring countries, it can be found as a park plant on the Black Sea coast of the Caucasus and in the Crimea.
The Cycling Cypress can be grown as a houseplant. In this case, it usually grows in height no more than 60 cm. Like all cycads, it prefers well-drained soil. It tolerates transplantation.
Cygnus is drooping poisonous to humans and animals when eaten. It should be noted that the taste of the plant is attractive to pets. Clinical symptoms of poisoning occur within 12 hours and may include vomiting, nausea, weakness, and cramping.
All parts of the plant are poisonous, especially seeds.

The Cycling Cypress, like its cousins, is a dioecious plant. Its column-shaped trunk, protected from the environment by a hard shell from the bases of outdated leaves, adorns itself with a rosette of cirrus dark green leaves, effectively decaying in different directions, like palm leaves. Inexperienced in botany, people often take the Cygnus drooping for one of the varieties of the Palm. However, Sagovnik is a more ancient creature of nature than Palm, having a very simple organism, which in its genetics is much closer to Fern, also living in lush forests of the Jurassic period.
Cycas grows drooping very slowly, reaching, as a rule, a height of three to three and a half meters. Some old-timers can grow up to seven meters. Large cones grow on males, pollen from which is transferred by insects and wind to female sporophylls. The roots of the plant are able to fix nitrogen from the soil.
Cycling cygnus grows more successfully in sunny places, but also tolerates partial shade. The plant is unpretentious to soils; it can grow both on dry and on moist soil, but succeeds in dry soils.

The Cycas is a very spectacular plant, living for a long time, growing slowly, which is suitable for growing it not only in open ground, but also as a plant in greenhouses and indoors. Compared with its counterparts, this species of the genus is quite cold-resistant, withstanding short frosts of minus ten degrees, and therefore this plant can be found, for example, in the UK. In our country, the Cygnus is drooping growing in open ground on the Black Sea coast.
The picturesque plant is given by its dark green cirrus leaves, the length of which varies from half a meter to one and a half meters. With this length, the stems droop beautifully to the surface of the earth, creating a semblance of a low palm.
The decoration are the organs of reproduction of the Cycas, especially the cones of males.
The stems of the Cygnus drooping, like many other representatives of the genus, contain a starchy substance that local residents actively use in their diet. Although the plant contains toxic substances, after heat treatment the toxicity disappears.
The stems of the Cycas are dried, crushed to a powder and mixed with brown rice. The starchy core of the trunk is cut into pieces and eaten baked, or turned into a starchy powder, from which dumplings are prepared, as well as cereals called "sago".
The poisonousness of Cygnus drooping in metered amounts is used by healers of human ailments as an expectorant, diuretic, tonic, astringent.
Leaves of the Cycling Suspender are used in the treatment of malignant tumors, in particular liver cancer.
Seeds facilitate coughing (expectorant). They are used as a tonic, as well as stimulating menstruation. Used in the treatment of rheumatism. Substances released from seeds slow down the growth of cancerous tumors.
Types of Cycas
Tsikas Revolution (cicada drooping) is compact, in connection with which it has gained special recognition in the circles of flower growers. A small thickened shoot of this species is crowned by a rosette consisting of 10-15 cirrus leaves of dark green color.
Snail-shaped cicas (curled cicas) has large dimensions in comparison with the previous view. Its foliage from the middle to the upper part in the region of the central vein is covered with thorns.
Cycas close to the previous species, grows in Madagascar. In the natural environment, its height can reach 10 meters, while the upper part of the plant often branches, and the seeds are the size of a goose egg!
Siamese cicadas extends to a maximum height of 1.8 meters. But the length of its sheet can be 1.2 meters (width - no more than 20 cm).
Rumph Cycas grows in Sri Lanka, in India, Indonesia and Papua New Guinea. For this species, without exaggeration, huge growth is characteristic - more than 15 meters.
Cicas crescent It was named so because of the curvature of the foliage, which is also versatile - glossy in the front and dull in the back.
Tsikas home care
Unlike natural living conditions at home, indoor cicada is limited to a height of 1.5 meters, the maximum length of its leaves is 50 cm. Although it grows slowly, it lives very, very long time with proper care - several hundred years!
The plant belongs to the category of photophilous, therefore it should be placed only in the southern part of the apartment, where it will feel great, even when it is in direct sunlight. In the summertime, the cypress is placed on the balcony or in the garden, so that the light intensity increases gradually (otherwise the palm tree may get burned, especially in the afternoon). In the place where the cicada is located, there should not be drafts and powerful winds, but being in the open air itself tempers and stimulates its growth.
The optimum temperature for growing in summer and in the off-season is 20 ℃, the humidity level should be increased, which is achieved by spraying and washing off dust from foliage under the shower at least 2 times in 14 days. Performing any type of irrigation, whether spraying, watering and so on, do not allow water to get on the cone, which is recommended to cover with polyethylene so that only the leaves remain open.
Zamia is also a representative of the Cycas family, has an elegant appearance, which allows her to become a living decoration of the interior. You can find all the necessary recommendations for home care in this article.
Watering requirements are not less. As in case of supersaturation of the earth with moisture, and in the conditions of its drying out, death is threatened by cicasus. Thus, you should adhere to the frequency of irrigation once for every 7 days during the summer.
Water should be slightly warmed up and settled for at least 12 hours. The intensity of irrigation in the spring-summer period should be calculated on the basis that before the next given procedure the soil should slightly dry.
It is important to maintain the moisture of the earthy coma throughout the entire volume, and excess liquid must flow out onto the sump, from where they are drained 20-30 minutes after watering. If the air temperature rises in 20 ℃, it is worth strew the pallet with moistened gravel.
Primer for cicas
The soil must pass water well, be neutral or slightly acidic. Planting is usually carried out in a palm soil mixture, which can be purchased at a flower shop. And in order to make the substrate yourself, you need to mix 2 parts of turf land with leafy soil, humus, peat and sand (all in the 1st part). Plus, on the drainage layer you will need small stones or ceramic shards.
Before planting cicadas in the prepared mixture, it is worth disinfecting it by repeatedly pouring boiled water on it or keeping it for 15-20 minutes in an oven heated to a temperature of 200 ℃. So you can significantly reduce the likelihood of damage to certain diseases, which will be discussed later.
Tsikas transplant at home
A transplant of a cicas before the age of 5 should be performed every year in the spring, then every 3-4 years with an annual replacement of the topsoil.
When replanting this plant, it is important not to shake and not wash the root system, and also to maintain such a depth of planting that the bump is located on the ground surface. The above mixtures are suitable as a substrate, do not also forget about the drainage layer.
Pot of cicas
Tsikas needs to pick up such a pot so that its dimensions are not so large that the excess of unoccupied soil will become an accumulation of acidified soil, and you need to change it when transplanting only if the space in it becomes really small.
To begin with, a vessel a couple of centimeters larger in diameter compared to the diameter of the stem of the plant and a depth of 2-2.5 times the diameter (for example, with a diameter of 20 cm, the depth is 40-50 cm) is quite suitable.
Fertilizer for cicas
From mid-spring to late summer, that is, at the growth stage, the cypress palm tree must be fed twice in 30 days. For this purpose, apply palm fertilizer, a traditional complex fertilizer for indoor plants (without calcium and magnesium salts) and organics in the form of dry cow manure.
When autumn comes, the frequency and concentration of top dressing should be reduced - up to 1 time in 30 days and half, respectively. The plant also responds well to orchid and cactus fertilizers. Before applying fertilizer, you need to moisten the soil, otherwise the roots may burn. It is impossible to fertilize a sick cycad, in winter, immediately after a transplant, with a lack of lighting and low temperature.
Tsikas is one of those plants whose flowering at home is extremely rare. If this phenomenon happened by some miracle when grown in a pot, the formation of large orange seeds 3-5 cm long is observed in the upper part of the trunk in females (cicas - dioecious).
Nevertheless, it is unlikely to be used for breeding purposes, since this requires greenhouse conditions and specialist experience.
Formation for the cygnus is an empty phrase, but pruning will most likely have to be done (purely for sanitary purposes). It includes only the removal of old dead leaves and damaged leaf blades.
Any such actions are carried out with gloves, since the cicada contains poison. Moreover, access to animals and children should be strictly limited.
Tsikas in the winter
In winter, a rest period for cicas comes. A suitable temperature for this time is 15 ℃ (no less), and it is optimal to maintain a higher temperature of the soil compared to the surrounding.
The plant likes to be near winter with sources of heating and additional illumination with special fitolamps. The second level the daylight hours, which should not be less than 12-14 hours.
Watering at this time should be no more than 1 time in 10 days, the soil in between watering should dry out by one third. The amount of moisture required by the plant varies depending on temperature and lighting, and therefore, with the approach of spring, the water supply should be gradually increased, just as it decreased before winter.
Tsikas breeding at home
Of the 2 existing methods of propagation of cicas in a room setting - seed and children - it is advisable to use vegetative, since self-growing seeds is a very difficult task. On the contrary, children propagate this plant, in principle, under the power of everyone.
Tsikasa give on their trunks young stems resembling bulbs. These processes in the second half of winter or in early spring should be carefully cut (it is better to choose those whose diameter is equal to or greater than 3 cm), processed in fungicide and dried for 24 hours. After this, the children are ready for planting in a peat-sand mixture, where they will take root for 6-9 months in moderate watering.
Before starting the procedure for separating the stems from the trunk, it is necessary to clean the first of the mud accumulations, and the separation itself should be done using a disinfected chisel, trying not to do any harm to the mother plant. After cutting off the wound of an adult plant, they are treated with paraffin, garden varieties or fungicide, and until healing occurs, watered with great care, protecting the cut area from water.
The processes also do not hurt to process in a growth stimulator. Young specimens show better rooting in conditions of high humidity, partial shade and at a temperature of 28-30 ℃. As soon as the children take root, they are transplanted into a standard soil mixture.
Diseases and Pests
The most dangerous pests for cicas are considered shields and thripssettling on its foliage, petioles and trunk. The results of their “invasion" appear in damage to foliageeducation on her yellowish (sometimes purple) spots, drying and falling off.
The parasites are eliminated with a soft damp cloth, and if the infection has passed into a more active phase - treatment with karbofos or actellik (15-40 drops per liter of water).
Of the diseases associated with improper care of the plant, it is worth highlighting lengthening and yellowness of foliagethat end either with its death, or a slowdown in plant growth for years. This is due to lack of lighting.
If you don’t keep the chicas cool in the winter, he can react to it. dropping foliage.
And the most common problem is root rot and caudex (lower zone of the trunk). Faced with it, you should carefully remove the palm from the pot, shake off the substrate from the roots, separate all areas with blackening, darkening and softened using a sharp sterile knife, and dip the plant in dissolved fungicide for 30 minutes.
Then each section is sprinkled with crushed charcoal and the plant is left to dry for several hours. After treatment, the cicada is planted in a new pre-sterilized soil, moistened before planting its root system in a root formation stimulator. If he takes root completely discarding the foliage - this is normal, because at the moment he is recovering from the disease.

Tsikas: home care. Briefly
In order for home to please the cicada for many years with its magnificent decorative look, it is necessary to ensure constant care and maintain an optimal microclimate:
|Temperature mode||Moderately warm weather is preferable + 23-25 ° C - in the summer and not lower than + 14 ° C - in the winter.|
|Air humidity||Cygnus develops well with an ambient humidity of about 80%.|
|Lighting||Good lighting with shading from the bright sun is required.|
|Watering||It is necessary to keep the soil moderately moist.|
|Primer for cicas||Light fertile soil with good air exchange.|
|Fertilizer and fertilizer||Organic feeding during the active vegetation period 1 time per month.|
|Cicasus transplant||Conducted after 4-6 years, transshipment of the root ball without destruction in a more free capacity.|
|Breeding||Reproduction is carried out by sowing seeds or vegetative processes of the stem.|
|Growing Features||Needs constant maintenance of an optimal microclimate without drafts.|
There is no flowering in the usual form of cicas, it has special organs for reproduction. There are male and female plants. At the top of the trunk of female plants, fairly large cones (megasporophylls), similar to a nest, are formed. Fertilize their males (microstrobils), in the form of elongated cones.
After fertilization, large seeds are formed with a length of 3 to 5 cm, oblong shape. Numerous loose scales serve as their shelter. Even the best quality care for cicas at home rarely leads to flowering, this can happen in a plant no younger than 15 years old. To obtain full seeds, artificial pollination is required.
The optimum temperature for active growth in the summer is from +22 to + 28 ° C. Cycas also tolerates hotter weather, adapts well to growing in the summer in the fresh air. Withstands short-term frosts, but may lose part of the leaves. A prolonged lack of heat can lead to the development of rot and loss of the plant.
At home, the cicas plant is regularly sprayed with warm, settled water. Spend it in the morning in the warm time. Periodically, the leaves are wiped with a soft, damp cloth. Do not spray cicada during flowering and in cold weather. In order to maintain humidity, the trunk is wrapped with wet moss - sphagnum, spray water near the plant.
In order for the plant to have an attractive, healthy appearance, it is necessary to provide the most bright, uniform lighting. Direct sunlight shades slightly. Daylight hours should last 12-14 hours. In the garden, the flowerpot is placed in partial shade.
Homemade cicadas are periodically turned to the light in different directions, so that the crown has a symmetrical appearance. With a lack of lighting, the condition of the plant worsens, the leaves are pulled out, take on an underdeveloped appearance.
Weak illumination for a long time leads to yellowing of the leaves, their death and complete halt of plant growth.
Tsikas is a fairly drought tolerant plant, but it should not be allowed to completely dry out. It is best to keep the soil slightly moist. Water for irrigation should settle well and have room temperature. During the period of active growth, plentiful watering is carried out as necessary, but at least once a week.
The loose soil is watered in two stages, the gap between which is a few minutes. In this way, the soil is evenly moistened. Residual water is removed from the pan. It is not allowed to hit the cone when watering, in order to prevent its decay. In autumn and winter, the intervals between watering are increased, and the amount of moisture is reduced.
Fertilizer and fertilizer
The cicada plant is fed at home from late March to October. During the period of winter rest, he does not need additional doses of fertilizers. Do not feed plants after transplantation, in low light and lack of heat. Excess fertilizer can do more harm to the plant than their deficiency.
Solutions of organic fertilizers: mullein or horse manure are more suitable for feeding. As a mineral top dressing, a special complex for palm trees is used. In order not to burn the roots with fertilizers, moisten the soil before dressing.
Cycas grows slowly and does not need a frequent transplant. Young shoots are transplanted into larger containers as they grow, adults - not more often than after 3-4 years.
Transplantation of cicasus is carried out by the method of transshipment while maintaining the integrity of the root coma. Fresh soil fill the free zones around the roots and update the top layer.
As necessary, trim the damaged leaves and old ones that have fallen below the horizontal plane. In this case, it is better to cut off completely dried leaves. In the warm season, the cicada is taken out to the balcony or garden, placed in places protected from the scorching sun, gradually adapting to new conditions.
For hygienic purposes, the leaves of the plant are periodically washed under a warm shower, protecting the trunk and the core of the outlet from moisture.
Growing Cycas from Seeds
It is practically impossible to get full-fledged cicas seeds at home, so it is better to buy them for sowing. Fresh seeds have good germination if favorable conditions are created for their germination:
- Seeds are soaked in warm (up to 35 ° C) water for 10-12 hours.
- The soil mixture is prepared from a mixture of peat and sand or perlite.
- Sow the seeds, slightly pressing to the soil, sprinkle with a thin layer of soil.
- Germination container is covered with a film
- Maintain a temperature of 20-25 ° C, soil moisture and daily air.
- After 1-1.5 months, seedlings will appear. The shelter is removed, the container is transferred to a well-lit place.
- In the phase of 1-2 real leaves, seedlings are transplanted into separate pots.
Propagation of cicas by side shoots
For vegetative propagation, lateral processes similar to bulbs, which sometimes appear in the lower part of the trunk, are used. The shoots are cut with a sharp knife in late winter or early spring, without damaging the mother plant. Sections are treated with fungicide and sprinkled with crushed charcoal.
The bulbous young shoot is dried during the day and placed for rooting in moist perlite or peaty-sandy soil. Before the formation of roots and the appearance of new leaves (from 3 to 6 months) maintain a temperature of +25 to + 30 ° C and moderate humidity. As soon as the stalk starts growing, it is carefully transplanted into the ground.
The species is quite compact and it is it that is cultivated at home. Numerous leaves are collected in a thick outlet in the upper part of a short (no more than 3m), thick trunk (with a diameter of 30cm to 1m). Depending on the growing conditions, the leaf length can vary from 50cm to 2m. The shape of the leaf is narrowly linear, with one central vein, sharp at the apex, tapering to the base.
An upright leaf plate is gradually bent outward, for which the variety also has the name "Cycas bent." Young leaves are abundantly pubescent, have a light green color. With age, the leaves become leathery, glossy, lose pubescence and darken.
Cicas curly, or cochlear
The trunk of the plant is columnar, on its top are collected in bunches (up to 30 pieces each) cirrus, flat, with a well-developed middle vein leaves. The leaf bundles are initially directed upwards, and with age they occupy a semi-horizontal position.
Short description of growing
- Bloom. Tsikas cultivated as a decorative foliage plant.
- Illumination. The bush needs diffused bright light or partial shade.
- Temperature mode. During the growing season - room temperature, in winter - at least 15 degrees.
- Watering. In winter, it should be scarce, and in summer - moderate.
- Air humidity. High - from 70 to 80 percent. Experts advise often enough to moisten foliage from a sprayer, and also its surface should be wiped with a moistened soft cloth, and the trunk should be regularly wrapped with moistened sphagnum moss.
- Fertilizer. Such ferns are fed during intensive growth once every 4 weeks, for this they use organic matter, which does not include magnesium and potassium, for example, a solution of horse manure or mullein is well suited. It is not recommended to use mineral fertilizers for top dressing.
- Rest period. It is relative, begins in late autumn, and ends in the first spring weeks.
- Transfer. Young bushes are transplanted once every 2 or 3 years. Transplanting adult ferns is not recommended; however, the top layer of the substrate must be replaced every year in the pot. To do this, remove the top layer of soil mixture with a thickness of about 50 mm, and then pour a fresh substrate into the pot.
- Breeding. To do this, you can use lateral offspring (if any). Only specialists can grow cicadas from seeds.
- Harmful insects. Scabies, aphids, mealybugs, spider mites.
- Diseases. Root rot, rot of caudex, chlorosis.
Features of Cycas
Externally, the cicada has many similarities with a palm tree, so it is a tree, the height of which can vary from 2 to 15 m, while its trunk is quite thick. If the plant reaches a height of about 300 cm, then the thickness of its trunk in girth, as a rule, is 100 cm. The surface of the stem is “chained in a shell”, consisting of the remains of leaf plates that have already died out. Twice pinnate or cirrus foliage is similar to fern leaf plates that grow from the top of the trunk. The lifespan of such a plant most often exceeds 100 years.Tsikas in indoor conditions has a height of 0.5–0.8 m, while within 1 year the increase in growth is no more than 30 mm, and he also produces only 1 row of sheet plates. Young leaf blades of deep green color, soft and with a slight pubescence, after a while they darken, become naked, hard and shiny. When grown indoors, this plant is very similar not to a tree, but to a bush. Interestingly, most gardeners believe that the cicada is a palm tree, because even its name comes from the ancient Greek word “kykas”, translated as “palm tree,” but in fact this plant has nothing to do with palm trees. However, it is a relative of the fern. Since this plant is slow-growing, it is often grown as a bonsai.
When grown indoors, such a crop blooms extremely rarely. On the top of the trunk of a female plant in the cones, large orange seeds form, the length of which varies from 30 to 50 mm. But in order for the seeds to be germinating, the cicada should be grown in greenhouse conditions, and the efforts of an experienced specialist will also be required.
Such a plant needs high humidity (from 70 to 80 percent). To increase the level of air humidity, it is recommended to regularly moisten foliage from the sprayer with well-settled water, wrap the trunk with moistened moss, and often wipe the surface of leaf blades with a moistened soft cloth.
Growing Cycas from a Seed
In indoor conditions, it is very difficult to propagate cicadas by seed method. As a rule, experienced specialists in nurseries or greenhouses do this. The fact is that in indoor conditions such a palm tree blooms extremely rarely, and even if this happens, there will be no one to pollinate the flowers. If you have a good seed in your hands, then it must be placed in lukewarm water for 24 hours before sowing, after which the seeds are evenly distributed on the surface of the perlite and slightly pressed into it. Place the crops in a warm place (at least 25 degrees). The first seedlings should appear 2-3 months after sowing. After 1-2 months after the emergence of seedlings, they must fully form one real leaf plate. When this happens, the plants are transplanted into individual containers in the soil mixture intended for adult bushes.
How to propagate by the appendix
If the plant is kept in conditions unsuitable for it, then offspring appear on its trunk. Take a very sharp knife and cut off the offspring, while trying not to injure the barrel. Cut off the entire foliage from the offspring, treat the cut with a fungicidal preparation solution, and then Kornevin. Then the offspring should be planted in very coarse sand or large perlite, after which they are watered. Be sure to carry out the processing of the cut site on the mother plant, for this use coal powder. At the time of rooting, the offspring are placed in a shaded, warm (approximately 30 degrees) place, while it is necessary to ensure that the soil mixture is constantly slightly moist. The offspring should take root in 6-12 months. When this happens, it is carefully transplanted into the soil mixture intended for growing adult cicas.
The greatest danger to cicas is represented by scale insects because they have a wax coating that protects them from the effects of insecticides. Adult insects from the bush are manually removed, and to destroy the larvae, the aerial part of the bush is treated with a system or contact agent, for example: Karbaril, Piriproksifenom, Acefat, Pyrethrin or other pyrethroids. Bushes are processed in the morning or evening, while the air temperature in the room should be below 30 degrees. If necessary, the bushes can be sprayed again after 5-10 days.
Mealyworms can also settle on such a plant. They can be found on all parts of the bush. After harmful insects are collected by hand, the bush is sprayed with a product that includes cypermethrin, and the substrate is necessarily wetted with such a preparation in a container. If necessary, the palm is treated after 5 days again. You can spray the bush up to 4 times.
If the aphid has settled on the plant, then it needs to be treated twice or thrice with an interval of 7 days with phosphorus.
In order to get rid of plant mites that settle in the aerial part of the bush, you need 3 sprayings, which are carried out with an interval of 7 days, for this, a solution of acaricidal means is used.

Very often, flower growers are faced with the fact that the foliage on the bush turns yellow. Despite the fact that this problem occurs very often, in most cases the plant can be saved. But in order to help him, the first thing to do is establish the reason, because of which the leaves turn yellow, and there may be several:
- micronutrient deficiencies
- insufficient nitrogen in the substrate,
- improper lighting
- trauma to the root system.
The first problem is most often associated with the fact that the plant was not fed on time or it couldn’t properly absorb the fertilizers due to the very low temperature or because the pH of the substrate changed, this happens when the bush is systematically watered with hard water. As a result, the development of the root system stops. If the cicada feels a lack of nutrients, then it needs to be fed, and the new foliage that appears on the bush will be of normal color. If he turns yellow due to improper care, then he will need a transplant into a fresh substrate, and he will need to start looking after him according to all the rules. If there is not enough nitrogen in the soil mixture, then nitrogen-containing fertilizer will have to be added to it, but old leaf plates will still remain yellow. If the reason is in improper illumination, then in this case it should be taken into account that each species has certain lighting requirements, in this regard, yellowing of the foliage can be associated with both an excessive amount of light and its lack. In some cases, the yellowing of the leaf blades begins after the bush is transferred to fresh air in spring, without first hardening it. Yellowing of foliage in cicas can be observed due to insufficient or very frequent watering, and even in the case when the root system is cold or the bush was fed with an excessively concentrated nutrient mixture. In these cases, the root system signals the presence of a problem by yellowing of the leaf plates, so when such a signal appears, you should try to make every effort to save the flower.
Curled cicas, or cochlea cicada (Cycas circinalis = Cycas neocaledonica)
The height of the column-shaped trunk reaches about 300 cm. The length of the leaf plates is up to 200 cm, they are collected in bundles of several pieces. While the foliage is young, it is directed up, and then it is placed horizontally. On the cirrus leaves there are from 50 to 60 pieces of densely arranged lanceolate leaves on each side of the midrib, their length reaches 25 centimeters, and their width is up to 15 mm.
Tsikas medium (Cycas media)
This palm-shaped tree can reach a height of about 7 m. The length of cirrus leaf plates is up to 1.8 m. The foliage is part of the outlet located on the top of the trunk. The length of small male cones is about 25 centimeters, while female cones are similar in appearance to a bunch of ears. In the 19th century, in Northern Australia, the seeds of this plant were used for food, but they were first subjected to special treatment, because they are poisonous.
Tsikas Siamese (Cycas siamensis)
The native land of this species is the savannah forests of Indochina. The height of the bush reaches only 1.8 m, while the trunk from the root to the middle is thickened, and then it becomes thinner. The length of the cirrus leaves is slightly more than 100 centimeters. They include pointed narrow linear whitish-blue leaflets, whose length is about 10 centimeters and a width of 5 millimeters.
