When to fertilize orchids in spring and what kind of fertilizer to apply
I. Early spring fertilization: In early spring, when orchids are still blooming, there is usually no need to fertilize them. Because fertilizing during the blooming period may cause them to fade prematurely. However, if you forget to fertilize them before they bloom, causing the nutrients in the growing medium to lack vitamin A, which is not suitable for their flowers to open normally, you can apply a small amount of phosphorus and potassium fertilizer to provide nutrients and help them rebloom.
II. Mid-spring fertilization: The official start of fertilizing in spring is around April. At this time, the flowers of orchids have withered, and the buds have already grown out, which is when they need nutrients. Fertilizing at this time can provide nutrients for the growth of new buds and help them grow stronger. In this case, applying some compound fertilizers containing nitrogen is more beneficial for the growth of their leaves.
III. Late spring fertilization: Some orchid species will bloom in summer and enter the budding stage in late spring. If you are raising such a species, you should stop applying base fertilizer in late spring and switch to applying phosphorus and potassium fertilizers to help with bud formation. If the species you are raising does not bloom in summer, there is no need to change the fertilization method in late spring, just continue to apply base fertilizer as usual.
