Popular views
The genus of Ktenant has about one and a half dozen varieties, but the most decorative and popular among them are:
- Ctenanthe compressed (Ctenanthe compressa). A small compact plant with huge glossy leaves of saturated green color, pointed at the ends. In length, with good care, the plate can reach 40 cm, in width - 12 cm. There is a small pubescent area at the bottom of the sheet.
- Ctenanta Oppenheim, or Giant Bamburant (Ctenanthe oppenheimiana). One of the highest flower species, can grow up to a meter in height, but the leaves are small, only 15–18 cm. A distinctive feature of the species is the velor structure of the leaf on the front side and the bright red color on the back. The characteristic pattern is beige and silver wide stripes from the center of the sheet to the periphery.
- Ctenanthe Burle-Marx or Burle Maxi (Ctenanthe burle-marxii). One of the lowest species, even in nature, does not extend above 40 cm, and at home it has a height of 20–40 cm. It differs in particularly lush, angular-shaped foliage with a pointed tip. The color is grayish green with darker stripes. The reverse side is red. Flowers bloom in the upper part of the plant, have a delicate beige color and small size.
- Ctenanthe Lubbers (Ctenanthe lubbersiana). Under natural conditions, it can reach a height of 150 cm, but a house usually grows to about half this size. A sheet plate with yellowish transverse feather-like spots always has a very bright emerald background color, which does not lose its saturation even in low light conditions.
- Ctenantha bristly, pubescent, or Setosa (Ctenanthe setosa). It can grow up to a meter in height. The color of the leaves is silver at the base and dark green in the upper part. The reverse side of the plate is red. It has a very fast growth.
Microclimate
As a true inhabitant of the tropics, the comb flower has very high demands on temperature, lighting and humidity. Without observing these conditions, the plant can easily be lost, so you need to worry about them in advance.
Location
When choosing a place for a crocodile leaf, you need to take into account the characteristics of the growth of this flower in nature. There the pretender prefers to hide in the shade of tall trees, while constantly being in a very humid and warm environment characteristic of the tropics. Thus, under indoor conditions, the flower will be equally uncomfortable with both the southern and northern windows: in the first case, the too bright sun and dry air play a negative role, in the second, on the contrary, the lack of light and heat. From this point of view, it is optimal to place the pot near the eastern or western windows. In the absence of such an opportunity, on the south side, the flower will need to be removed away from the window, on the north - additional illumination.
It is also important to protect the flower from drafts, although ventilation will not hinder it at all.Important! You can not put a ctenant next to heating appliances, since they very much dry the air, and this factor is harmful to a tropical plant.
Lighting
In the summer, for the crocodile leaf, direct sunlight is most dangerous. In general, the plant is shade-like, therefore, in partial shade it feels quite comfortable. However, in winter, when the number of clear days in the middle lane sharply decreases, the flower begins to lack light and heat. Based on these rules, lighting should be correctly varied depending on the season. The condition of the decorative leaves will tell how correctly this condition is met: their size decreases, and the brightness of the color is lost in cases of excess light, with insufficient lighting, the sheet plate becomes lethargic.
Temperature
The comb flower is not as demanding on temperature conditions as it is on other climatic conditions, however, it is very important for the plant that these parameters be constant: the flower does not like sudden temperature changes, including day and night.
The crocodile leaf feels best when the temperature of the soil is in the range + 18 ... + 22 ºC, air - + 22 ... + 25 ºC. It is advisable not to allow the room to cool below +18 ° C, a critical indicator at which the plant can no longer develop normally is cooling to +16 ° C.
Air humidity
At home, the hardest thing is to provide the ctenant with sufficient air humidity. The plant needs an indicator of at least 70%, better - up to 90%, which is almost impossible to achieve in residential premises.
You can solve the problem by regularly spraying the plant. However, since it is not always possible to do this several times a day, it is better to moisten the air by placing a container filled with sphagnum or other water-absorbing material near the flowerpot and constantly adding fresh water to it. This method is also preferred because drops that fall on large leaves during daylight hours are reflected in sunlight and cause burns, which causes the appearance of dry brown spots on the leaf plate.Did you know? In the evening, the leaves of the ctenantas gather at the base, and with the first rays of the sun they blossom again: in this way, a rustle is created from them, and it seems that they seem to come to life.
Some gardeners place the ctenant in decorative florariums, aquariums or terrariums, where it is much easier to create a plant suitable for it microclimate.
Proper care
In addition to providing the flower with the necessary level of humidity and temperature, caring for a crocodile leaf requires proper watering, regular feeding, transplanting and some other specific activities.
Watering
A ctenanta, like any other tropical plant, needs regular and plentiful watering, and it is very important to ensure that the soil in the pot is completely moistened, and not just its top layer.
For watering, it is best to use soft and purified water. Tap water is too hard, so it must first be allowed to stand as long as possible. Before watering the plant, the water should be heated to a temperature a couple of degrees higher than the temperature in the room. Such precaution will avoid the development of root rot. For the same reason, stagnation of water in the roots must not be allowed; for this purpose, the pot must include drainage holes, and the water flowing into the sump must be poured out.It is best to water the crocodile leaf in the upper way, while the water does not pour under the root, but over the entire area of the pot. The lower watering is less suitable for the plant, since it does not provide the complete wetting of the entire land lump and at the same time draws useful trace elements from the lower soil layer.Important! The frequency of watering depends on the air temperature: the colder the room, the less watering should be done.
Fertilizer application
The comb flower does not show special requirements for dressing. In order to prevent soil depletion, it is sufficient to apply complex mineral and organic fertilizers, diluted according to the instructions, sold in flower shops and intended for ornamental-deciduous plants, twice a month immediately after irrigation during the active vegetation period (from mid-February to the end of October) . Some experts even recommend halving the prescribed dose, as crocodile leaf reacts very poorly to excess mineral additives. In winter, when plant growth slows down, the frequency of top dressing is reduced to once a month or a half.
It should also be borne in mind that diseased or recently transplanted flowers should not be fertilized, this procedure is an additional stress that can weaken a weakened plant.
Support
Low-growing varieties of the comb flower (Ctenanthe burle-marxii or Ctenanthe compressa) do not need support, however, for higher plants, such support is necessary, otherwise the bush will lose its compactness and decorativeness. There is no need to build a solid structure for these purposes, since crocodile sheets are not rigid and heavy.
The plant should simply be held in a vertical plane, for this it must be limited in the ability to tilt branches in different directions.
Various flower supports are sold in flower shops in assortment, but you can simply install several wooden, bamboo or plastic trims of suitable length in a pot around a circle and tie them with a thread or rope, leaving the plant inside an impromptu frame.
Pruning
As a mandatory procedure, pruning of the ctenant is not necessary. It does not form a decorative crown and does not have a pronounced dormant period, when excessive green mass can interfere with it. If any of the leaves has lost its decorative effect (yellowed, dried, covered with sunspots, curled up in a tube), it must be carefully removed, without forgetting to analyze the causes of the problem and correct the situation. For reasons of aesthetics, it is also necessary to remove dried inflorescences after the plant has flowered.
Transfer
The young ctenant is transplanted regularly, once a year, and the already formed one is 2-3 times less likely, with the annual addition of fresh soil mixture to the pot. The best time for these purposes is the period of the beginning or end of the growing season (February or October), although some recommend replanting the flower in late spring or summer.The comb flower prefers light, loose soils rich in humus. Acidity is neutral or slightly acidic (the optimal pH level is within six).
You can independently prepare a suitable composition by mixing:Important! It’s unlikely that it will be possible to find a special soil mixture for sale, so when buying finished land you should focus on the substrate for azaleas.
- sheet earth - 2 parts;
- peat - 1 part;
- coarse river sand - 1 part;
- charcoal - 0.25 parts;
- sphagnum moss - 0.25 parts.

Before embarking on a transplant, a thick layer of drainage material should be poured into the prepared pot, then covered with a fresh substrate on top. It is advisable to carry out the transplantation by transshipment: remove the plant with an earthen lump, without exposing the roots, place it on the surface of a thin layer of earth in a new pot and then add the required amount of soil mixture on the sides and top. After filling the flowerpot, you need to compact the earth well and, if necessary, add a little more soil on top of the sagging soil.

Breeding
A ktenant at home reproduces vegetatively. Two possible methods are used for this - rhizome division and rooting of cuttings.
Did you know? Some plants exhibit a truly amazing trick in trying to survive, while capturing new territories. For example, the cycloid stork is named after the stork’s beak-like shape of the seeds, which, as they ripen, twist into spirals, and then, released into the wild by a gust of wind and the spring mechanism of an adult plant, find a “landing site” and are screwed into the soil, as it were, like a corkscrew.
Dividing the bush
This method is the simplest, but requires great accuracy. Its meaning is to cut the rhizome into 2-3 parts during transplantation, and then divide the whole bush along the cut line: each fragment should consist of an independent root and the size of the aerial part corresponding to it in volume. The cut line on the root for disinfection can be sprinkled with wood ash. Then each new plant is planted in a pot according to the standard technology used during transplantation (in this case, a larger tank is not necessary, since the plant becomes smaller). For better rooting, a little more peat can be added to the soil mixture.Freshly transplanted plants are watered with warm water and covered with a plastic bag to create an artificial greenhouse. The package is periodically removed for ventilation, and after young shoots appear on the flower, they are completely removed.
Cuttings
Cuttings of cuttings are best carried out in late spring or early summer, when the day is already long enough, but still far from the heat. Young shoots are used for rooting. The procedure is as follows:
- From the top you need to cut a fragment from 7 to 10 cm long, it should have 2-3 healthy leaves.
- Cuttings need to be placed in water for rooting. This process takes quite a lot of time, sometimes up to a month and a half, therefore, given the increased requirements of the plant for air humidity, it is best to place the container with cuttings in a glass jar or cover it with a film.
- After the appearance of the roots, the cuttings are planted in a peat substrate and placed in a warm, moist and slightly shaded place.
- When young plants form a few fresh leaves, they can be planted in individual pots in a permanent place.
Growing difficulties
Violation of the requirements for the care of the plant can lead to various diseases. Usually, by the appearance of decorative leaves and other characteristic features, it is easy to determine what exactly the comb flower is lacking.
Disease
When growing plants, you may encounter such problems:
- Shriveled and dropped leaves. A clear signal that the air in the room is too dry. The problem is eliminated by moisturizing.
- Darkening of the tips of the leaves also speaks of reduced air humidity.
- Lethargy and decay of the leaf plate. Usually occurs when the air temperature is unacceptably low. The pot needs to be placed in a warmer place.
- Light spots on the sheet. So the plant reacts to direct sunlight, especially if it was sprayed with water. The flower must be shaded.
- Dark spots on the leaf plate. The reason is the stagnation of water in the soil. This is especially true for the period when the room temperature drops. It is necessary to adjust the watering and, if necessary, transplant the flower, providing for reliable drainage in the new pot.
- Asymmetric growth, a characteristic bias towards the window. Occurs when sunlight is not enough for a flower. You should move the pot to a more suitable place or arrange artificial illumination for the plant.
- The appearance of a “black leg” on the stem, brown spots on the green parts, the presence of mold on the surface of an earthen coma, sometimes the presence of an unpleasant odor of decay coming from the soil. Indicates the development of root rot - a dangerous fungal infection. If you start the disease, the plant will die, and it will need to be thrown out along with the land in which it grew. Radical treatment is required: the bush is cut so that only perfectly healthy shoots remain on it. Slices are sanitized (wood ash, activated charcoal or ground chalk can be used). The plant is removed from the pot, the roots are freed from the ground and washed in a solution of fungicide such as “Topaz”, “Abiga-Peak”, “Previkur”, “Alirin-B”, “Baikal-EM” or “Skor”, after which in the same the solution is soaked for 30 minutes. Then the flower is transplanted into a new pot with completely fresh soil (the previous substrate cannot be reused). Over the next few months, fungicide for prevention should be added to the water for irrigation.
Pests
Of the pests for ktenanty danger are:
- aphid;
- scale shield;
- mealybug;
- spider mite;
- whitefly.
Did you know? “Praying flower” - another popular name of the ctenantes - has nothing to do with religion and superstition. Before sunset, the plant raises its decorative leaves up, as if for prayer, although in reality it’s just catching the last gentle rays (there is a version that such a “prayer” of the plant indicates the approaching rain).
Regardless of which parasite caused this phenomenon, an effective method of treatment is to treat the green parts of the flower with water, with soap, alcohol, crushed garlic or onion juice. In case of severe damage, the flower should be sprayed with a special preparation, in order to avoid mistakes, it is better to use universal means - both against insects and against ticks. Among the best-known drugs suitable for these purposes are, for example, Akarin, Aktellik, Aktofit, Apollo, Vermitek, Fitoverm or Fufanon.
Ktenant Myths
Folk rumor describes the ctenant mainly as a plant favorable for growing a house, although it is often spoken of as a flower with an ambiguous energy. And yet, on the whole, most often the comb flower is credited with magical power to protect the house from evil forces, strengthen mutual love between spouses, calm, relieve stress, improve sleep and even cure protracted diseases.Plant experts are sure that a ctenant can be safely placed in a nursery, as well as in the conjugal bedroom, as well as in the room where an elderly person lives. From such a neighborhood, the condition and mood of households will only improve.
Crocodile leaf - the plant is very elegant, but, unfortunately, it is difficult to attribute to unpretentious ones. Caring for such a indoor flower involves creating conditions that are not entirely compatible with the living room (mainly regarding humidity), but placed in the decorative flora of Ktenanta will become a real decoration of the home, filling it with cosiness and positive energy.
