These are the best ways to deal with fertilizer burn on Orchids.

  1. Water 3 out of every 4 times with clear water and no fertilizer.
  2. If the fertilizer salts are built up quite a bit, repot the Orchid.
  3. Be careful in the future not to over fertilize.

To tell if you have fertilizer burn, look for these signs:

  1. Burnt tips on Orchid leaves.
  2. Old mix that has salts building up on top.
  3. Blackening parts of your Orchid.
  4. No bloom.
