Weakly, Weekly

When it comes to fertilizing, a good rule of thumb is to feed orchids “weakly, weekly.” Orchids do best with a weak fertilizer solution given weekly during spring and summer. It’s common to use ¼ – ½ the strength recommended on the package label. A dilute fertilizer solution mimics how orchids obtain nutrients in the wild, usually in small doses. It also avoids problems caused by too much artificial fertilizer. Blackened roots or black leaf tips are typical signs of overfeeding. When orchids are emerging from dormancy, new growth is especially susceptible to fertilizer burns.

Be sure to flush all orchids with clean water occasionally, at least once a month. This removes fertilizer residues which can build up and cause damage.

    Following my own investigation, I have found that weekly weakly works best. My orchids have lots of blooms and I stopped having fertilizer burn. I use the method for all my plants, not just my orchids. Its on my calendar every week and I don’t have to think about it after that.

    Question: the Weekly weakly method

    The directions for my fertilizer says 1 tsp per gallon of water. Do I feed my orchid weekly until I run out of the fertilized water?

  7. Marc Says:

    To eve: Most fertilizer instructions tell you how to mix a gallon, but that’s too much if you don’t have a big orchid collection. Some fertilizers may lose potency over time, especially if the bottle is stored in the heat or sun. You may want to do the math and mix smaller batches so you don’t have to store it.

    […] Fertilizing weakly, weekly is best. Compost can also be a great growth booster. […]
