This Florikan 17-5-11 (N-P-K) 180 day time-release fertilizer is a good round number for growing orchids and is best applied in spring. The more heat, the more the fertilizer releases. It's convenient for those who don't always have the time to prepare fertilizer, and it also is a good extra boost to your regular fertilizer program for orchids that like heavier feeding during the grow season like Vadas, Denrobiums and Stanhopea etc.
