1. Basin soil

To choose a sandy soil that can drain water and maintain moisture and good ventilation, you can use sandy soil, moldy soil, compost soil and sand in a ratio of 3:4:2:1 to prepare soil suitable for the growth of crab claws. When planting in a pot, you can put about 2cm of small stones in the bottom of the pot, then spread a thin layer of soil, then sprinkle some decomposed chicken manure, bone meal and hoof horn chips on the thin soil as base fertilizer, then add a thin layer of culture soil on the base fertilizer, then put the crab claw orchid in the center of the pot, add the soil prepared before to maintain the original depth, then compact the soil, pour water thoroughly and put it in the semi-shade.

II. Watering

Crab claw orchid likes to grow in a semi-shady and humid environment, and in its growth period, it should keep the soil moist. It can be watered once a day or every other day.

Fertilization can be stopped during high temperature in summer, fertilization can be carried out weekly in autumn to provide sufficient nutrients for flower formation, and 1000 times of potassium dihydrogen phosphate liquid fertilizer can be sprayed on leaf surfaces once a week in winter.
