My own orchid collection has species and hybrids from all over the world, but only one that’s native to San Francisco.

Many orchid experts subscribe to the maxim “weakly, weekly,” meaning that a weak mixture of fertilizer given on a regular basis can go a long way to improving orchid growth and blooms.
