Can Orchids Use Compound Fertilizer? This Article Explains It All

Orchids need these key points met, and they can use compound fertilizer. Orchids can generally be given one application of compound fertilizer after blooming in spring and one before budding in autumn. Each time, apply about 20 granules of a compound fertilizer with an N-P-K ratio of 17:17:17. First dig a shallow ring-shaped trench along the edge of the flower pot, apply the fertilizer, then cover it with soil and water. This helps orchids produce buds more easily and makes the plants more robust. You can also use a compound fertilizer with a higher phosphorus content during the flowering period, diluted with water at more than 1000 times, and spray it.
