Clusia - a genus of evergreen plants of the Kluzievye family, numbering, according to various sources, from 150 to 300 species, distributed mainly in the tropical regions of South America, although some of them can also be found in North America.
The genus was named after Karl Clusius (Charles de Lecluse), one of the most famous European botanists of the 16th century. Among the types of clusia, there are also those that can be grown in room culture.
Planting and caring for a clusion
- Bloom: usually in the spring.

Clusia are evergreen shrubs and small trees, most often epiphytic. Carried by birds or the wind, the seeds of the clusion germinate in the plexus of the branches of the host plant. First, the epiphyte forms aerial roots that securely attach it to the bark of the tree, then gradually the roots grow, reaching the soil and strengthening in it. The host plant, crushed by the roots of the clusion, dies after a while ...
In the photo: How the clusion blooms
Clusia has bright green, smooth and bare leathery leaves arranged in opposite order on short petioles. Full-edged lanceolate or oval-shaped leaf plates with a pointed end can reach a length of 8 to 20, and a width of 5 to 8 cm, but there are also small-leaved forms of clusia. Emitting a subtle, but pleasant aroma, flowers with four to nine waxy petals of greenish-white color with pink or yellow spots reach a diameter of 5 cm. The flowers open at night, and close in the morning. The fruit of the clusia is a round box with a diameter of 5 to 8 cm, covered with a light green skin. When the fruit ripens, the skin gradually darkens, turns brown, the fruit opens star-like, and you can see many seeds inside it in red pulp. The fruits of the plant are inedible, and the juice, when it comes into contact with the skin, causes irritation.
Clusion care at home
Clusia needs long daylight hours (10-12 hours) and diffused light: do not let the sun's rays fall on the leaves of the plant from 12 to 16 hours. With insufficient light, the internodes of the plants stretch out, and the clusion takes on a painful appearance. The best place for a plant in an apartment - a western or eastern window sill, but you can also keep it in the immediate vicinity of a well-lit window. In the fall, winter and early spring, when the day is getting shorter, use artificial light sources to increase the daylight hours.
A comfortable temperature for the clusion is 22-25 ˚C, but with the end of the growing season, the plant prefers to rest in cooler conditions - at 20 ˚C. The room in which the clusion grows needs to be regularly ventilated, but make sure that there are no drafts in it.
In order for the clusion to develop evenly and form a symmetrical crown, once every two weeks, rotate the pot with the plant around its axis by 180 ˚.
Watering and feeding
The clusion is watered infrequently and not too abundantly: between waterings, the substrate in the pot should dry out by a third or even half the depth, and in no case should water stagnation in the roots of the plant be allowed. Watering is carried out with water at room temperature passed through a filter or separated for two days.
In the summer heat and in winter, when the air in the room is dried up by working heating devices, you need to spray the leaves of the clusion with warm, settled or filtered water.

The cultivation of a clusion involves the introduction of fertilizing into the substrate twice a month, but only during the period of active growth, that is, from April to October. A solution of a universal mineral complex is used as a fertilizer, and at half the dosage recommended in the instructions. During the dormant period, the houseplant of the clusia does not need fertilizers, however, if it is in the same conditions in winter and summer, in winter, apply fertilizing once a month.
The clusion is very painful to transplant, therefore, when changing the pot and substrate, they use the transshipment method. This procedure is carried out when it is found that the clusion has completely stopped growing. They take a large pot, not very deep, but with a wide bottom, fill it a quarter with drainage material, carefully transfer a clusion with a large earthen clod on the roots to the drainage and fill the remaining space with fresh substrate, which can consist of equal parts of leafy soil, sand and garden earth or from leafy earth, peat, coniferous earth, sand and vermiculite, taken in equal proportions.
After transplanting, the clusion is watered and shaded for a while from direct sunlight. Top dressing is resumed no earlier than a month and a half after changing the substrate.
Reproduction of the clusion
The home flower clusia propagates vegetatively: by layering and cuttings. The apical sections of the stems 15-20 cm long can be rooted in a wet sandy-peat substrate, having previously processed the sections with Heteroauxin or Kornevin, or simply in water. It is advisable to keep rooting cuttings at a temperature of 25 ˚C, covered with a transparent cap to create increased air humidity. The roots of the cuttings grow for about a month, and when they reach a length of 1-1.5 cm, the cuttings are planted in pots with a substrate for an adult plant.
The filamentous aerial roots feeding the clusion grow over time, acquiring a dense structure, and then the shoot with an aerial root can be separated from the mother plant and planted in a separate pot. The first time you need to protect the layers from direct sunlight. In the future, he is looked after as an adult plant.
Clause pests and diseases
Diseases and their treatment
Clusia rarely gets sick, but sometimes it can get in trouble due to improper conditions of detention or mistakes in care. For example, insufficient lighting can lead to the fact that the leaves of the clusion begin to turn yellow and fall off, and from chronic waterlogging on the leaves of the plant, fungal plaque appears, which, spreading, leads to decay.
If you find signs of a fungal infection developing on the terrestrial organs of the clusion, remove the flower from the pot, remove the rotting areas with a sharp sterile tool, grabbing some healthy tissue, transplant the plant into a fresh substrate and review the watering regime.
Pests and the fight against them
Of the pests, the clusion can be attacked by scale insects, mealybugs and spider mites. All these parasites make bites in the leaves of the plant and feed on its sap, which is why the clusia withers, and its leaves and young shoots are deformed.
Upon detection scale insects and worms you need to remove them from the leaves with a cotton swab dipped in alcohol or soapy water, after which the plant is washed with soap in the shower, protecting the substrate with a film from water and soap getting into it. The plant is allowed to dry and the leaves are treated with an insecticide solution.

Spider mites - very small arachnids, settling on the underside of leaves and weaving the finest web. You can find out about their presence by small discolored dots on the leaves - places of bites. Washing the clusion under the shower should scare the pests who love dryness and heat, but if the mites have time to breed, washing alone will not eliminate the problem: you will have to resort to treating the plant with acaricidal preparations.
Types and varieties
Large clusia (Clusia major)
Or pink clusia (Clusia rosea) not so long ago appeared in room culture. This upright compact evergreen plant is undemanding to the conditions of maintenance and care. It reaches a height of 1 m. The leaves of this species are large, whole-edged, glossy, leathery, opposite: each subsequent pair of leaves is at right angles to the previous one. Clusia grows slowly and rarely blooms, but under favorable conditions and good care, fragrant, waxy, like a magnolia, white flowers with pink spots, about 5 cm in diameter with a bright yellow center, open on it.
- Rosea Princess - clusion with green leaves and large pink flowers;
- Variegata - variegated variety of pink clusia with a yellowish border around the edges of the leaves;
- Yellow Variegate - a plant with yellow spots on the leaves.

Breeding technology (seating) dieffenbachia
At home, with proper care, the flower grows quickly. The root system grows, occupying more and more space in the pot, and after a while you can notice that the plant undergoes negative changes:
- foliage growth slows down
- the soil in the flowerpot dries quickly after watering
- when visually examining the root system, you can see a dense interlacing of roots and a lack of soil.
If you notice such changes, it's time to think about transplanting dieffenbachia into a large container. Transplanting must be done in February or March, when the movement of sap in the plant occurs at a slow pace. This process must be performed correctly, be careful not to harm the plant:
It is important to transplant the plant on time
- Prepare a pot 2 or 3 cm larger than the previous one.
- The substrate must be disinfected, or a new one must be used.
- Completely renew the drainage material.
- Carefully remove rotten or diseased roots.
- Pour drainage and part of the substrate into the prepared container.
- Place the plant with a root ball of earth in a pot, cover the root with new soil.
- Slightly compact, water abundantly.
An unpretentious plant does not require special care; at home, two requirements should be met:
- Observe the cultivation technique, that is, properly water and feed the plant, keep it in a comfortable environment.
- Fight pests - aphids, scale insects, using chemical and organic means, using folk methods.
Dieffenbachia attracts the eye, pleases with its freshness in summer and winter, creates coziness in the house. Try and grow such a miracle in your apartment, country cottage, or greenhouse.
