Potted orchid culture should master three elements! Do you know what it is?

(1) cultivated soil. Orchid is a perennial root plant, which requires soil rich in humus, fertile and loose, pH 5.5 to 6.5. Potted soil is used with rotten leaf soil, yellow mud, sawdust, pig and cow manure and certain compost, which is fully mature and sterilized by sunlight before potting. Orchids are most afraid of waterlogging, but also afraid of drought, appropriate watering, it is appropriate to keep the basin soil moist, to ensure the coordination of water and fertilizer. Usually use Amoy rice water to mature and irrigate, not only for nourishment, but also for water, which is beneficial to the growth of orchids.

Orchids have weak roots, improper fertilizer and water management, easy to rot roots, wilting and yellowing branches and leaves, and even plant death. To prevent rotten roots, one is to strictly prevent waterlogging in the basin, and the other is to find rotten roots of yellow leaves and change the basin in time. The orchid plant was poured out of the basin, cut off the rotten roots, washed with clean water, soaked in 500 times potassium permanganate solution for several hours, re-planted in the pot with aseptic new culture soil, put in a cool place to promote new roots. If the rotting root is serious, after root cutting and disinfection, soak the root with 2% to 4% sodium borate solution or acetic acid rooting powder solution for 4 hours, fake plant in fine sand, send out new root, and then transplant it into the basin.

Do not apply fertilizer. Generally stop fertilizing when the flower buds show color to prevent the petals from withering early. No sun. Orchids like semi-shade, every day to maintain enough scattered light to prevent direct light, especially in the flowering period to put cool and ventilated places to prevent flowers from dying early. Don't touch the root. Do not change the pot, ramet, do not move the root, appropriate watering to keep moist, maintain the normal absorption and metabolism of the root system, prevent flowers from dying early, and prolong the viewing period.
