In the open field, the liana develops only in a tropical climate; in the middle lane it is grown in greenhouses or rooms. Due to the rapid growth of shoots and abundant flowering, it is widely used for decorating large rooms, halls, decorating walls, decorating winter gardens and greenhouses. In home floriculture, it is grown as an ampelous or climbing plant, or, with proper pruning, it forms into a small bush (up to 45 cm).

Like many representatives of the kutrovy family, the culture is poisonous, all its parts contain dangerous cardiac glycosides . Care must be taken when caring for a flower, especially if there are small children in the house.

Tips for Growing Diplodia: Care, Pruning and Propagation

For successful cultivation of Diplosion, its care must take into account the tropical origin of the plant. This vine is photophilous, feels good in full sunlight, requires shading only on hot summer days. It is thermophilic, during the period of growth and flowering the optimum temperature is 20-25 ° C, in winter – not lower than 12 ° C. The plant does not tolerate drafts. Needs abundant watering, but without waterlogging, leading to root rot. In the summer months, it is watered with soft water at room temperature every 2-3 days after the soil has dried to a depth of 1-1.5 cm, less often in winter. This tropical crop needs moist air. It is ideal to place it in a closed flower display case, or place it on a pallet with moistened pebbles or expanded clay and spray it often with soft water, trying not to get on the flowers. For better flowering, wilted inflorescences are removed, damaged and dried parts are cut off in a timely manner. Fertilize every 2 weeks with a complex mineral fertilizer, adding it to the water for irrigation.

Starting in January, the room flower of diplatia goes into a dormant state. At this time, watering is limited, top dressing is excluded, and a temperature of about 12-13 ° C is provided, which is favorable for laying flower buds.

If young specimens cease to grow, in the spring they are transplanted into larger pots, where expanded clay drainage and acidic soil from peat, sand, leaf and sod land are placed in equal amounts. The maximum pot size is 20-30 cm, in the future, the topsoil is replaced annually.

Diplosion pruning is a necessary technique that ensures abundant flowering, since buds form only on annual lateral shoots. It is produced in autumn or spring immediately after being brought into a warm room, while the old stems are cut off at the level of the soil surface, the rest are shortened, leaving about 5 cm. In young plants, pinch the tops. When grown as a vine, the main stem is left intact, cutting off only the side branches.

Propagation of diplodia is carried out by stem cuttings harvested in spring from green side shoots or in summer from semi-lignified stems. They are placed in a substrate of peat and agroperlite in equal parts, provide high air and soil temperature (up to 25 ° C) and humidity, for which they are placed in a mini-greenhouse. After rooting, on average after 3-4 weeks, they are planted one at a time in pots with a diameter of 12-14 cm.

Pests and diseases of diplatia: why leaves turn yellow and how to deal with ticks

Of the pests, the most dangerous is the spider mite, when damaged, small brown dots first appear on the leaves, then they turn yellow and may fall off. To combat the tick, acaricidal or insectoacaricidal preparations (akarin, agravertin, or their analogues) are recommended.

Diploidia diseases are usually caused by unsuitable growing conditions or care errors. So, excessive watering or the use of poor-quality soil contributes to root decay, and a lack of moisture, and especially dry air, cause leaves to fall, their paleness and drooping, flowers and buds to fall.

Insufficient lighting leads to a reduction in the flowering period, the flowers become small and few, the leaves lose their color.

If the leaves turn yellow in diplatia, this may be due to waterlogging, low temperatures in winter or too high temperatures in summer. Lagging in growth and development often indicates a lack of nutrition.

Diplatia is considered one of the most spectacular domestic vines, but it will please you with a healthy look and long flowering only with proper care in compliance with all the above recommendations.
