Nitrogen and phosphorus fertilizer is good. Generally speaking, in the growing period of the crabapple orchid we can apply a thin nitrogen fertilizer to promote plant growth, and then we apply phosphorus fertilizer before flowering.

Crab claw orchid fertilization should generally be in the growth period, it should be noted that there are buds and flowering, do not water more, do not fertilize, otherwise it may lead to bud drop. In addition to crab claw orchid fertilization should also distinguish whether grafting, grafting with a small amount of composite fertilizer or liquid fertilizer, rootstock, most of the more fertilizer-resistant, if the cuttings should be careful, no matter whether you're a white crab, red crab or pink crab, the root system is very intolerant of fertilizer, accidentally have to burn the roots, so each time the fertilizer used is 3-5 composite fertilizer amount of a word, a word "thin! ".

Crab claw orchid belongs to the cactus family, drought intolerant, often because of watering more than rotten roots, available in suitable plastic pots with a pistol drill to play it 20 or so holes, especially the bottom side more to play, so that watering more water will leak out, will not be stagnant, the roots deeper, while facilitating the soil permeability.

Crab claw orchid every two years need to change pots, usually in March to April. When changing pots, the main attention to fertilization, first in the bottom of the pot on a layer of 3 cm of coarse sand particles, to facilitate drainage, and then add a small amount of decomposed animal manure or bone meal fish scales and so on, to increase the fertility of the soil. Be careful that the root system does not come into direct contact with the fertilizer, so as not to cause fertilizer damage to affect growth.

No grafted crabapple orchid, its root system is generally less developed, and after grafting crabapple orchid, its root system is more developed, resistance is also stronger. It is important to grasp the fertilization when it is grafted, which is conducive to the growth of the plant. Do not fertilize immediately after grafting, first put the plant in the shade, a week later, after the grafting incision is dry, the first fertilizer after watering, fertilizer to liquid fertilizer-based.
