Can compound fertilizer be used to grow orchids?

Compound fertilizer can be used to grow orchids. There are many types of compound fertilizer; taking a compound fertilizer with 17% each of nitrogen, phosphorus and potassium as an example, it can generally be used before flowering in spring and before bud formation in autumn. Dig a shallow ring-shaped trench 5-8 cm from the roots, sprinkle in about 20 granules of fertilizer, then cover with soil and water.
