Orchid Plant Food

Orchid plant food should be 20% or less nitrogen. The amount of the phosphorous and other nutrients is not so important.

Some growers like to use a slow release formula, however, this can sometimes burn roots and in course potting material, can be easily washed out during watering.Therefore, a water soluble fertilizer is recommended. It is widely available, and easy to apply. It will need to be reapplied every 2-3 weeks.

Tips on Fertilizing:

  • Feed when orchids appear to be growing.
  • When they stop growing, stop fertilizing.
  • Very dark green leaves that are limp, have probably been over-fertilized.
  • Every few weeks, wash out excess fertilizer salts by flushing the plant growing medium with plain water.
  • It is better to under-fertilize than over-fertilize.
