Orchids need some basic rules when it comes to fertilization, because without using good fertilizer, orchids won’t grow or bloom. If they are over-fertilized, the roots and leaves of the orchids may suffer burns and blossoming is no longer produced.
Rules for orchid fertilization
1. Use special fertilizer for orchids, because chemical dosing is made in accordance with their needs.
2. Read the instructions on the fertilizer container carefully before purchasing or before planting.
3. Respect carefully the prescribed doses.
4. The fertilizer must contain nitrogen, phosphorus, potassium and iron traces.
5. The plant should be watered before adding fertilizer.
6. Never add concentrated fertilizer. If is liquid form it should be diluted, and if are granules you should dissolve it in the recommended water dose. If you apply concentrated fertilizer, the plant may suffer severe burns.
7. If you use vase-masks, after watering and applying the fertilizer, make sure that water won’t leak out of the pot. Water doesn’t have to pour into the bottom of the pot (it is also available for plates under the pot).
Tips for experienced orchid careers
1. The ratio of nitrogen, phosphorus and potassium in the fertilizer used to fertilize orchids may vary depending on plant activity.
2. Orchids that have growing leaves must receive a more nitrogen-containing fertilizer.
3. Also, the species that are cultivated on a pine bark substrate (Orchid faleno, for example) need more nitrogen because the bacteria that decompose the substrate, consume the existing nitrogen, and the orchid won’t benefit of the fertilization.
4. When flowering triggers, the amount of nitrogen administered must be reduced in favor of potassium and, in particular, phosphorus, which is responsible for the abundant flowering.
