4. When and how to transplant an orchid?
Orchids do not tolerate transplanting, so they should not be transplanted more than once every three to four years after the flowering period. It is advisable to do this in the spring and not only when the plant needs more space for growth. Transplantation is required if the substrate in which the orchid grows corrupted, if the roots rot or dry, if the leaves begin to dry.
For transplantation, use special soil for orchids. Such soil can be purchased in specialized departments or compiled by yourself. Orchid outlets sell not only natural substrates, but also synthetic ones. The substrate should be purchased only from natural ingredients. Fillers from synthetic materials accumulate salts, decompose over time, releasing toxins, which leads to the cessation of growth and flowering of plants.
A good substrate consists of bark and cones of conifers, peat, moss, charcoal, chopped walnut shells, coconut nuts. It should pass moisture well, without holding it, provide free access to air and at the same time be a stable support to the plant.
Control and timely replacement, partial renewal of the soil will protect it from rotting and the development of bacteria. The selection of a specific composition of the substrate depends on the microclimate of your home. If the necessary conditions for growth are violated, a change in its composition is required. For example, with high humidity add bark or charcoal, with dryness – fern roots and coconut.
Let the orchid dry a day before you decide to transplant it. Carefully remove rotten and dried roots before putting the plant in new soil. After transplanting, the plants are not watered for several days.
During the year, if necessary, it is enough to change the top layer of the substrate. Carefully remove it from the pot and sprinkle fresh. Make sure that the pseudobulbs remain free and do not burrow into the ground. Otherwise, it may cause them to rot.
5. Does the orchid need winter peace?
A period of rest is necessary in order for the orchid to gain strength for the next flowering. During the rest period, when the orchid loses its flowers, in order to get the blooming orchid again faster, it is necessary to prune the stem. Some types of orchids can bloom repeatedly without a long break. It is best to cut off the old branch above the third eye, then a new shoot will appear on the remaining stem.
The stem should be cut with a sharp knife or garden secateurs, so that the cut is smooth, and thereby reduce the possibility of the spread of microbes. Then sprinkle the slice with activated charcoal powder or treat with a disinfectant from the first-aid kit, iodine and zelenka are suitable.
After pruning, the plant can be placed in cooler conditions for several weeks, but make sure that it still gets enough light and air.
If the stem is completely dry, it must be completely cut off. This will lead to the appearance of new peduncles.
