What kind of plant material should be used for orchid cultivation? The key is to loosen, ventilate and drain water.
Novices can mix humus, perlite, dead bark, peanut shell and broken bricks. The proportion depends on personal needs. The humidity in the south is large, and there are more particles. The dry in the north, there are fewer particles.
Generally, large particles are placed under the flowerpot, and fine particles are placed in the middle and upper part, so as to facilitate drainage.
Orchid watering is a test of skill. If your plant material is clean, loose and airy, it is not afraid of water, but of sultry and airless. Once watered, it will rot.
So to judge the time of watering, we can pull the upper layer of the plant material apart, touch the soil to see if it is still wet, and if there is moisture, we will not pour it; another one can shake the weight of the flowerpot, and if it is lighter, it means that it should be poured.
However, there is still a risk of rotten roots or empty roots in this way. An experienced old orchid friend shared his tips with you. If you are interested, you can try:
Prepare an orchid basin with the same material, put the same plant materials in it, do not plant orchids, and water it at the same time. I want to know whether it is necessary to water to turn the plant materials out. The wet answer is that there is too much water and ventilation is needed.
Too dry, indicating that the orchid is thirsty and badly in need of watering. It's not wet or dry, it's just the right moisture.
Orchids are shade plants. They don't like strong light and direct light. In autumn, the light at noon is still a little strong. You should avoid the soft light before 9 a.m. and after 4 p.m.
There is a large amount of humic acid in the orchid plant material, generally speaking, it does not need to apply fertilizer. In autumn, you can apply a thin slow-release fertilizer, mainly AOLV No.1 or magnesium AOLV fertilizer, bury the particles on the basin surface, and slowly release the fertility with watering.
Note: the seedlings in the new basin do not need to be fertilized for half a year, and the novices do not need to fertilize within 1-2 years.
For the orchids blooming in spring, it is suggested to change the pots every 1-2 years from late September to mid November.
1. Stop watering 3 days before basin change to make the soil dry;
2. Tap the edge of the flowerpot gently to remove the plantlet.
3. Grasp the base of the orchid seedling with one hand, and buckle the flowerpot with the other hand. Pull out the soil lump gently, and do not use excessive force.
4. Shake off the soil at the root, cut off the rotten root and empty root, wash them with clean water, and dry them in a cool place.
5. Select a slightly larger flowerpot, preferably a purple sand basin. Plant the blue seedlings in it and put them in a cool and ventilated place to slow down the seedlings.
