Zamioculkas (Zamiocúlcas), a celibacy flower or dollar tree, belongs to the monotypic plant genus from the Araceae family. The native land of the plant is tropical Africa, and when cultivated on the territory of our country, flower growers may encounter problems such as zamioculcas withered, and also do not give new shoots or do not grow and die slowly. That is why when growing an ornamental culture, it is very important to do timely disease prevention, as well as observe agricultural practices.
The herbaceous plant has a thick tuberous rhizome and glossy, dark green, complex feather leaves. The average leaf length reaches a meter. Leaves have a swelling on the base. Less than ten years ago, breeders obtained a miniature cultivar of the plant, represented by a compact bush with a height of not more than 0.6 m, with fine foliage.
Zamioculcases are unpretentious plants and quite easily tolerate reduced air humidity, as well as partial shading. However, for the full growth and development of the plant needs bright rooms and the absence of direct sunlight. Decorative culture does not respond well to excessive soil moisture and moisture congestionTherefore, irrigation measures must be strictly rationed. If the indoor plant is heavily flooded, it means that it is not easy to save the decorative culture, and it will be necessary to carry out a whole complex of restoration measures.
There are no special requirements for soil composition by zamioculcas, therefore, a houseplant grows well in self-made soil on the basis of sod, leaf soil and medium-grained sand, which are mixed in a ratio of 1: 1: 1. The culture can be propagated by dividing the tuber, as well as by rooting a leaf or a separate leaf plate.
Inflorescences of Zamioculcus are subtle and not too decorative, are light creamy cobs, formed on shortened and thick peduncles. The inflorescence is surrounded by a light green veil. In home floriculture zamiokulkasy bloom extremely rarely. It should be noted that the plant is poisonous, therefore, when transplanting and pruning or forming branches, as well as dividing tubers, increased safety precautions should be observed using rubber gloves.
The main vital organ of any plant is the root system, which in Zamioculcas includes a large tuber and the roots proper, growing from its apical part. At the first stage, the plant assimilates the volume and fills the flower pot, after which the tuber, which stores moisture, builds up. During this period, there is no development of the aerial parts of the plant.
Among other things, zamioculcas is a southern plant, so the activation of growth processes, accompanied by the formation of new shoots or stems, begins quite late and continues until the last decade of winter. The formation of shoots is observed in the so-called reserve buds, and the density indicators of an adult ornamental bush are directly proportional not only to the size, but also to the number of tubers.
When growing Zamioculcas, it is very important to take into account the biological characteristics of this southern decorative culture, since otherwise the plant becomes ill, and Zamiokulkas’s ill health is manifested in the appearance of yellow spots, drying out of the tips of leaf plates, loss of elasticity of the stem part. Failure to comply with agricultural technology causes yellowing, a decrease in leaf lobes and blanching. Such problems threaten not only a complete loss of decorativeness, but also the death of the plant.
Sometimes dark spots appear on the aerial part of the plant. The reasons for this phenomenon can be represented by a too wide range of temperature indicators in the growing room, the negative effects of drafts and abundant watering of zamioculcas. To rid plants of spots on foliage, it is necessary to completely exclude the presence of negative and traumatic decorative plant factors, including changing the regime of irrigation measures and temperature extremes. It is important to remember that the appearance of dark spots on foliage can also indicate damage to the decorative culture by plant parasites.
All amateur gardeners engaged in the cultivation of zamioculcas in indoor floriculture are very well aware of such an interesting phenomenon as the crying of a decorative flower, which is accompanied by the appearance of moisture drops on the ends of the foliage that really resemble tears. A houseplant cries when mistreated, including injured leaves, excessive fertilizer and excessive irrigation.
Many diseases of decorative culture are the result of improper care. Excessive irrigation can reduce the supply of oxygen and reduce drainage of the soil, which makes the full nutrition of the root system of the decorative culture impossible. The roots begin to rot, and nutrients do not enter the plant, which causes weakening of the stems. Thin and emaciated stems quickly sink. Also, thin trunks of Zamioculcas grow in low light. There are situations when the trunk disappears, but the plant can still be saved and as a result of observing agricultural technology, new shoots appear from the underground part.
If the stem wrinkled in Zamioculcas due to systematic waterlogging, then it is necessary to carry out the following activities as soon as possible:
If signs of decay or damage by fungal infections are detected during processing, it is very important to use fungicides in the treatment of the root system. Yellowing of the foliage can be observed as a result of a natural, age-related aging process, in which only the lower foliage falls. Almost complete loss of foliage is most often a consequence of improper care and mechanical damage.
One of the most common problems in growing such an exotic plant as zamioculcas is yellowing or changing the appearance of foliage of a decorative culture as a result of damage by plant parasites. The most dangerous pests are represented by spider mites, scale insects and aphids.
When affected by spider mites a thin cobweb forms on foliage and stems. The fight against this plant parasite can be carried out with water or in a physical way, as well as treatment with "Anticomp", "Zircon" or "Agravertin".
With a lesion with a scab on the foliage the appearance of dark spots and yellowness may be noted. This type of plant parasite is characterized by fairly rapid reproduction, so manual collection is not always effective and appropriate. In this case, it is desirable to use insecticides.
It is important to note that indoor zamioculcas needs quite competent care, and only in this case a tropical plant is able to delight the surrounding with chic, very decorative dark green leaves year-round.
