I don t know why I m dying of my crab claw orchid, ask for advice

The experience of raising crab claw orchid:

1. The soil is the old soil recycling, change the pot once every 2 years, the old soil is mixed with sheep manure and chicken manure, change the pot in May, the first 3 months of watering without fertilization, starting from August, every watering is put Biwang, in late September, after the bud is watered and must bloom, spray potassium dihydrogen phosphate once a week after October, with a concentration of 500:1.

2. Watering is dry and watered thoroughly, I am knocking on the pot, listening to the empty sound and the soil above is dry and then watering, the water is easy to rot the roots.

3. Crab claw orchid is placed indoors in the sunshine in winter, I am on the first floor, there are only 2 hours of sunlight a day in winter, and it is placed outside the north window in summer, and it is taken out of the south window after the bud in mid-September, and the temperature drops to 8 degrees at night to enter the house.

4. Only one bud can be left in one leaf, and the rest must be pinched off, otherwise the seedlings will not be slowed down for a long time after flowering, which will affect the flowering of the second year, and even exhaust the flowers to death.

5. After flowering, the leaves will wilt, which is normal, it takes 1-2 months to slow the seedling period, watering and adding a small amount of Biwang, if the conditions are good, the sun is sufficient, the water and fertilizer may keep up with the May will open once (my house is now not enough sunlight on the first floor, and it can be opened 2-3 times when living on the 5th floor) moved outdoors in May, I am leaving only one leaf per branch, and the rest is removed.

Is it watered too much, this thing can be watered once a week.

1. Knock the crab claw orchid out of the pot, cut off the rotten part, put it in a ventilated place for 1 2 days, and then replant it in a pot filled with yellow sand, place it in a ventilated and rainless place, do not need to water it within 3 5 days, and it will regrow new roots from the root after 10 days.

2. If it is a crab claw orchid grafted on a cactus, use the same method to cut off the rotten part and replant it.

3. If the tree is larger and has more branches and leaves, when using the above method, a part of the branches and leaves should be cut off to reduce water evaporation, which is conducive to the rooting. After taking root in autumn, it is transferred to normal fertilizer and water management, and it can still bud or bloom during the Spring Festival.
