When and what fertilizer to use for orchids in spring

1. Fertilization in early spring

In early spring when orchids are still blooming, it is generally not necessary to fertilize them. Fertilizing during the flowering period may cause it to flower prematurely. But if you forget to fertilize it before it blooms, the planting material will lack nutrients and cannot support the normal opening of its flowers. Then you can apply a small amount of phosphorus and potassium fertilizers to it to provide it with nutrients and help it continue to bloom.

2. Fertilization in mid-spring

Fertilization officially begins in spring around April. At this time, the orchid flowers have withered and new buds have grown out. It is the time when it needs nutrition. Fertilizing at this time can provide nutrients for the growth of new buds and new leaves to help it grow better. At this time, some compound fertilizer containing nitrogen should be applied to it, which is more beneficial to the growth of its leaves.

3. Fertilization in late spring

Some orchid species bloom in the summer and then form buds in late spring. If you are growing these varieties, you should stop applying nitrogen fertilizer in late spring and instead apply phosphorus and potassium fertilizers to help bud formation. If the species you are growing does not flower in the summer, then there is no need to change the fertilization method in late spring, just continue to apply nitrogen fertilizer as before.
