When spraying foliar fertilizer, pay attention to comprehensive and even spraying to ensure that each leaf is sprayed, adjust the spraying angle, and improve the effect of foliar fertilizer.

Fertilizer precautions

Because Bletilla striata absorbs nutrients entirely through its fibrous roots, when fertilizing it, you should apply fertilizer around the roots and allow the fertilizer to seep into the roots. This will ensure that the plant can fully absorb nutrients.

If you want to apply organic fertilizer to Bletilla striata, it needs to be fully fermented and decomposed, and avoid using raw fertilizer when applying fertilizer, and the concentration cannot be too high, otherwise fertilizer damage will easily occur, resulting in the plant being unable to grow normally.

When applying foliar fertilizer to Bletilla striata, be sure to spray every leaf of the plant to facilitate absorption, and the concentration and temperature of the foliar fertilizer must be strictly controlled.
