The culture method of tiger skin orchid

1. Soil: Tiger Pilan has lax requirements on soil, but its management can be relatively extensive. It likes loose sandy soil and humus, and is resistant to drought and barren. Potted plants can use 3 parts of fertile garden soil, 1 part of cinder, and then add a small amount of bean cake crumbs or poultry dung as base fertilizer.

Temperature: Tiger skin orchid originated in western Africa and southern Asia, distributed in tropical Africa and India, the suitable temperature for growth is 20-30 ℃, and the overwintering temperature is 10 ℃.

In the peak growth period, fertilizer can be applied once or twice a month, and the amount of fertilizer should be less. Standard compost can be used when changing pots, and dilute liquid fertilizer is applied once or twice a month in the growing season to ensure that the leaves are green and thick. You can also bury 3 holes of cooked soybeans evenly in the soil at the edge of the basin, each hole is 7-10 grains, be careful not to come into contact with the root. Fertilization was stopped from November to March of the following year.
