Turning over pots and changing plant materials of orchids are prohibited from changing soil within 2 years.

As we all know, orchid is a perennial herb, its growth rate is relatively slow. Like other plants, the growth of orchids also needs a relatively stable environment, that is to say, the plant material in the basin and the surrounding environment need to be relatively stable, which is not suitable for turning the basin and changing soil frequently. In providing orchids with a relatively stable condition, orchids can grow well for many years in a row, and will be better than a year. I have personal experience of this. Orchid friends who usually pay attention to observation should also find that the growth of the grass in the first year is not good, and the growth in the second year will be obviously better than before, and the new buds will be stronger than in the first year, that is to say, after a long time, the orchid has begun to adapt to the environment you provide it. And when it is just beginning to adapt to this environment, you have to replace it, so repeatedly, your grass will only grow weaker and weaker. The purpose of turning the pot is to divide the seedlings or replace the new plant material to make the orchid grow better, but turning the pot too often is counterproductive. Especially now we mostly use granular plant material, after turning the basin, the bonding degree between Langen and plant material will be greatly reduced, thus greatly affecting the growth of root system and the absorption of nutrients. Therefore, unless there is something wrong with my potted orchids, they are rarely turned over to change the soil within 2 years.

As for plant materials, I think orchid cultivation is actually a process of planting materials. Orchid friends who have raised fish know that raising fish first raises water, and that is the truth. When the plant material is well raised, the grass will grow better and better. In the case of proper management, as long as the newly grown seedlings do not show significantly weaker than the previous generation, it shows that the plant material is basically feasible and can continue to be used. Many orchid friends will pour out the plant material and change it and throw it away just when the plant material is not yet ripe or just ripe. What a pity. People who are reluctant to throw away the replaced plant material will sometimes use the old plant material to plant some common grass. You may find that the common grass planted with the old plant material grows much better than the one you raise with the new plant material. The reason is that as long as we figure it out carefully, it is not difficult to figure out why. As for the plant material, as long as it is not a diseased grass, I am all screened and reused. In particular, it should be no problem for mixed granular plants to be reused for ten or eight years without any change in their properties. Under the condition that the previously planted bluegrass has no adverse reaction, the old plant material should be added to the new plant material as much as possible to retain the blue flora already formed in the original plant material. Do not let the character and proportion of new and old plant materials change too much. Or, by planting, you can sum up whether the old plant material has any disadvantages, and it may be much better to adjust the proportion by adding some other plant material than to use it with a brand new plant material.
