A family of arrowroots. The homeland of the ktenant is the tropics of America: Brazil, Bolivia, Ecuador, Peru, Colombia, at an altitude of 100 to 500 m above sea level. In nature, there are 15 species. Ktenantu (also translated as Ktenante) is sometimes confused with calathea, they are really similar and closely related. All ctenants differ from other arrowroots in longer petioles - 2-4 times longer than the leaf itself, and in a more elongated shape of the leaf plate.

Ctenant compressed Ctenanthe compressa

  • Ktenant Oppenheim Ctenanthe oppenheimiana - among the ktenant is a tall species, up to 90-120 m tall at home in a pot, in nature about 150-180 cm. Leaves on long petioles, lanceolate, obovate at the base of the petiole, only about 20-30 cm long. Coloring of leaves with alternating gray and gray-green stripes. Ctenanthe oppenheimiana 'Tricolor' has several strokes of white and pink in color.
  • The species of Ctenanthe bristle Ctenanthe setosa is very similar to Ctenanthe oppenheimiana, the differences are subtle at first glance, even the height of the bush in the setosa reaches an average of 90 cm.In fact, the Ctenanthe bristle (setosa) has a wider leaf blade at the base, thinner stripes on the leaves, the reverse side of the leaf is purple, but the main thing lies in the name - the leaf petioles are covered with thick hairs. The leaves of Ktenanty Oppenheim are narrower and pointed towards the end of the leaf, the reverse side of the leaf is gray-green. Ktenanta Setosa cultivar Gray Star 'Gray Star' - differs in that the color of the leaf is almost completely gray or gray-green with thin stripes of green along the veins.
  • Ctenanthe lubbersiana is a medium-sized species about 80-100 cm tall. The leaves are oblong dark green above and pale green below in a natural species, there are several varieties, for example, with variegated veins (like a viral speck), which on the leaf vary from creamy yellow to light green, Variety 'Brazilian Snow' - in light creamy, almost white, broad stripes are colored almost half of the leaf, from the middle to the tip. Ctenanthe lubbersiana 'Tropical Dragon' - with wide creamy stripes.
  • Ctenanthe marantifolia Ctenanthe marantifolia - this species was previously called Ctenanthe pilosa, many people know the variety 'Golden Mosaic'. It has leaves about 20 cm long and 8 cm wide, dark green with light green and yellow blotches. The shoots have basal leaves at the base, the stem branches above, the internodes (the distance between the nodes) are about 50 cm.Golden Mosaic is the only variety of this species and it is practically a twin of the Ctenanthe lubbersiana of the Tropical Dragon Ctenanthe lubbersiana 'Tropical Dragon', both from Brazil, and they cannot be distinguished by a layman.
  • Nice ctenanthe amabilis - has typical elongated leaves of gray and gray-green color, differs in that it tends not to stretch upwards or grow in a compact bush, but to grow strongly in width. In nature, it forms low dense clumps, at home it widely fills the pot (not too high, but a wide container is required), the height of the bush is on average about 40 cm.According to the observations of flower growers, this species requires slightly more abundant watering than many others.
  • Ctenanthe burle-marxii is a dwarf species with many popular varieties. On average, the plants do not exceed 40 cm in height, the original form has rather wide, almost rectangular silvery-gray leaves in outlines with dark green stripes along the veins. The variety Ctenanthe burle-marxii 'Amagris' is even more compact - no higher than 30 cm, the leaves are silvery-gray on top, blunt at the end, the veins are painted green in very thin stripes, the reverse side with a lilac (purple) tint.
  • Ctenanthe compressa is of medium height, a bush of about 40-45 cm in height, leaves of a normal green color, without a bluish or gray tint, without contrasting stripes, there may be faint transverse stripes of a lighter green shade. In shape, the leaves, like those of burle-marxi, are almost rectangular in outline. Outwardly, this species is very similar to one of the arrowroot species, rather rare at home Maranta arundinacea. The difference is that the arrowroot has nodules on the roots, the ktenants have just juicy, even roots.

Care of the ktenant

Lighting ktenants
Lighting ktenants

On the north side, plants located not on the window, but in the room need additional lighting.

All varieties of ktenant need the same care, the only feature: varieties with light spots on the leaves need a little more light, although in nature they grow in semi-shady places, good enough lighting is needed throughout the year.

Temperature

Ktenanta is thermophilic, it is undesirable for the temperature to drop below 16 ° C, does not tolerate drafts and sudden temperature changes. Optimum in summer is 20-25 ° С, in winter 18-20 ° С. It should also be noted that the ktenanta does not like being moved from place to place. If you put the pots on the balcony, then take into account the night temperature drop, for the plant the critical border is + 13 ° C.

Lighting

Penumbra or bright diffused light. In a sunny or too dark place, the color of the leaves is lost. The sill of the east, north-west and north windows is well suited, you can put it next to the west or south window, under the shade of light tulle (veils, nets). In winter, make sure that the leaves do not touch the cold glass. Direct sun in the period before 11 o'clock and after 17 o'clock does not harm the ktenants at all and is even useful.

Ktenanta is considered one of the most shade-tolerant plants. A large plant is usually kept not on a windowsill, but on a table near a window or in a room. At the same time, if the window is not southern, then the plant may need additional lighting in winter. The lack of lighting is evidenced by the appearance of small new leaves in spring, the plant itself "turns and leans" towards the light source.

Watering

Sufficiently abundant during the growth period, but only after the top layer of earth in the pot dries out, the ktenant does not like excess moisture. If the pot is large, then wait two to three days, after drying the top layer of the earth, only then water. In cool conditions, watering is very moderate, with good soil drying. Water the ktenant only with soft filtered water. If you live in an area with no industrial emissions, it is best to use rainwater.

Fertilizer

From April to August, ktenants can be fed with complex fertilizer for indoor decorative deciduous plants, no more than once every two weeks, it is better to take the fertilizer in a concentration slightly less than the recommended one. The plant is sensitive to excess or overfeeding of fertilizers. After the transplant, the ktenant is not fed for at least a month. Read more about the features of care and fertilizers for arrowroots.

Air humidity

Ktenanta loves very humid air, 55-75% is optimal for her. In this regard, you need to take measures for possible humidification for the heating season. If from May to October, while the batteries are cold, the humidity naturally keeps within the required limits, then, as soon as the heating is turned on, the air becomes unforgivably dry, in severe frosts in winter, the humidity barely reaches 25%. This is so critical that no amount of spraying helps. The best way out is to put a humidifier next to it, if not, place the pot on a tray with wet sphagnum moss (moisten it regularly) and cover the batteries with wet towels or a damp sheet.

Ctenanthe marantifolia 'Golden Mosaic' - pay attention to the size of the pot - just right.

Transfer

Transplant the ktenant annually into light, well-drained soil, consisting of 2-3 parts of leafy soil, 1 part of humus soil, 1 / 5-1 / 6 part of fine gravel or zeolite granules. The easiest way to buy cat litter for toilets "Barsik" made of zeolite - such small gray-brown crumbs, the size of buckwheat. They need to be well washed from dust and mixed with soil. It's a good idea to add pieces of birch charcoal to the potting mix.

Another version of the soil mixture: 1 part of store soil (for example, Terra Vita), 1 part of coniferous soil, 1 part of coconut substrate (from briquettes). Store soil can be replaced with garden soil from cucumber beds, where the introduced manure is already well overwhelmed.

Any soil mixture must be sterilized in the oven before planting in order to destroy pathogenic microflora, nematodes and viruses. Choose a small pot for ktenants, you can choose a plastic one with large holes at the bottom or clay, and put a piece of coconut shell upside down as drainage.

Reproduction

By dividing the bush when transplanting in the spring. Remove the plant from the pot, cut 1-2 leaves with a small part of the roots on the side of the root ball with a knife. For planting, you should not take very spacious pots, in them arrowroots grow very slowly. Delenki are covered with a plastic bag and kept in a warm and bright place until the plants take root, which takes one to two weeks.

Features ktenant

All ktenants have the unique ability to turn leaves. We already know that arrowroots raise the leaves up at night, as in prayer, and spread them in the morning - this is how they orient themselves in space relative to the light, for this in their homeland - in the countries of Latin America, all arrowroots are called praying plants. But the pursuit of the sun (light source) is not the only reason for leaf turning. Sometimes movement is a pronounced defensive reaction; in sunny weather, the plant turns the leaves to reduce transpiration and excessive evaporation of moisture. If you look closely, the leaves turn along the light flux, sideways to the sun, by the edge of the leaf - this way the heating surface is less than when the leaves are in a horizontal position. Moreover, interestingly, the plant chooses how it is more convenient for it - it can raise the leaves up, or lower,almost perpendicular to the floor. Please note, if your ktenant suddenly pressed the leaves to the petioles on a spring or summer day, she may be hot or dry! The sun may no longer shine through the window, but the leaves are still pressed against the petioles. The fact is that in this position, moisture evaporation also occurs in a more economical mode - moisture inside the bush, between the petioles and pressed leaves, is preserved better than when the leaves are spread.than when the leaves are spread.than when the leaves are spread.

By the way, all other arrowroots can behave in exactly the same way, but only in ktenants, stromanths and some kalateas (large long-petiolate), this process is more pronounced. In arrowroot, the stem growth is different - semi-creeping, forming many nodes, and the bush is compact, so arrowroots from the heat also shrink like bristling hedgehogs, or the leaves are pulled closer to the walls of the pot.

Thus, observing your ktenant (or other arrowroot), you can understand - it is hot for her, too intense the sun, or both. To avoid burns and not overheat - the leaves will become an edge towards the light. But if there is no sun, look at the thermometer - it may be too stuffy, hot, remember how long you watered. With very strong dryness, the leaves become lethargic, like rags, but before that the plant will do everything to save moisture evaporation - it will squeeze the leaves.

In some cases, the leaves on one side of the plant are lowered, and on the other, they are raised, so you can observe the reaction to the flow of warm air from the battery and the orientation of the plant to the light source.

Growing problems ktenant

Ktenants, as a rule, are not prone to various diseases, but problems can arise when the air humidity is too low - the leaves dry and turn brown. Increase the moisture level by placing the plants on trays of damp pebbles or spray frequently (5-6 times a day). It is bad for plants in unventilated rooms, at any time of the year, when it is stuffy and hot. Ctenants do not tolerate toxic fumes from building materials - the edges of the leaves dry, turn yellow or turn brown, the plants inhibit growth. If the watering is correct, consider whether this is a reaction to smoke or evaporation of materials after renovating the apartment.

Pests: spider mites and mealybugs are the most likely threat. The best way to prevent pests is to keep the plants clean, regularly inspect and wash off the dust under a hot shower - arrowroots easily tolerate contact with hot water at 55 ° C.

Treatment: get rid of pests with the help of insecticides - watering and spraying with actara or confidor is best for worms. These drugs do not work against ticks - arthropods must be destroyed with acaricides: apollo, vermitic, actellic, etc. Repeat the course of treatment every ten days for a month.

Diseases: Ktenants can be susceptible to gray mold and other fungal diseases due to high humidity or excessive watering.

Prevention: Provide good air circulation around the plants, and watering as the soil dries, periodically loosen the soil in the pots.

Treatment: if the plant is already sick, you need to cut off the affected areas, replace the soil if mold is on it and apply a fungicide spray.
