I was just wondering the same thing.

I am going to cut back to once every couple weeks unless the plant tells me otherwise

example is multiflora who is putting out alot of new growth to replace what she lost, so as long as that keeps up i will keep feeding regularly

I fertilize year-round. Remember, most species being epiphytes, Hoyas receive nutrition on a pretty constant basis in the wild. The terrestrial species also receive constant nutrition year-round via rainforest floor detrius.

Conventional wisdom is "cut back" but I'm not cutting back on Foliage Pro or Root Pro. Bloom Pro, yes. But many of mine are young, so roots and foliage are what I care about over winter. That, and humidity and warmth will get me through winter, I hope.
