Is it harmful to change the number of wild orchids?

Orchids generally change pots and soil once a year, but this pot is judged according to the growth of flowers, such as the nutrients of the planting material have been exhausted, can not meet the needs of the continued development of orchid seedlings, orchid seedlings appear thin and short; After years of water and sun exposure, the structure of orchid mud has changed, and the planting material is compacted, which affects the ventilation and water circulation; There are too many orchid seedlings, and the roots are intertwined, and there is no room for new seedlings and new roots to continue to develop, which also affects the normal growth environment of old seedlings. After the orchid is potted for a period of time, it should be repotted at the appropriate time according to the actual situation of the planting material (the best time is to turn the pot in spring), so that the orchid can always maintain vigorous vitality.

Generally speaking, the vernal equinox, that is, March 21 to 22 of the solar calendar, is the heyday of germ growth of various plants, and the end of the dormant period of orchids is also the best period for repotting and planting. Yang Chun.

In March and April, temperatures in the south climbed from low to high. In the world, most of the orchid varieties have begun to germinate, some varieties have grown new shoots, and some varieties are accelerating their metabolism. In particular, it is important for those who are new to orchid cultivation to grasp this suitable season.

In fact, different places and varieties are different, and the repotting time is slightly different. Experience has proved that potting can be carried out all year round, but it is necessary to change potting in the hot and cold seasons, and it is necessary to take measures to prevent heat stroke and frost. If you change the pot, in addition to breaking the old pot, you can also wash the potting soil with water without damaging the orchid roots, but this is more water-intensive.

Precautions for changing pots.

1. When changing the pot, bring as much soil as possible to the roots of the plant, and try to avoid bare roots; This is due to the fact that transplanting with soil and empty is easier to survive than transplanting with bare roots.

2. When changing pots, if the original flower pot is a soft plastic pot (or paper cup), it is recommended to cut it open, which will not hurt the plant roots.

3. Do not change pots continuously in a short period of time, for general plants, between two pot changes, at least half a year or even longer; But for the plants in the nursery, there are special circumstances, depending on the growth of the seedlings, the seedlings grow up, you can change it, which can be changed often.

The timing of repotting depends on the season: it is most suitable for spring and autumn; Some plants are also suitable for winter.

The timing of repotting depends on the growth of plants: 1. It is most suitable for the dormant period and early growth of plants. 2. It is most unsuitable to be carried out in the vigorous growth period, bud stage, flowering period, and fruiting period of plants. Or let the plants that should bloom miss the flowering period, etc., the consequences are serious.

3. For plants that are in the slow seedling stage, do not change, because the flower roots are already damaged, and then changing at this time will cause secondary damage and prolong the slow seedling period indefinitely (it should have been restored in a few days, but it was forced to be delayed to more than ten days or longer).

In the summer high temperature season, orchids should be repotted without bridge socks, and the survival rate is too low

1. The permeability of the planting material must be good, and it must be fully sterilized and disinfected.

2. Don't water the roots immediately after planting, but wait until the second or third day to water.

3. After planting, it should be placed in a cool and ventilated place for careful maintenance, and a certain air humidity should be maintained.

4. Do not fertilize within three months.
