I always have good intentions of getting on a regular feeding schedule for my plants during the summer growing season but my attention span is not so great.

On the rare occasions that I do remember to feed my Hoyas, I use Better-Gro (11-35-15) orchid bloom booster fertilizer. I fill a 5 gallon bucket with water and dump in a couple of spoonfuls of the fertilizer (I always use less than the recommended amount listed on the package). Sometimes I will add a cap full of fish fertlizer to the bucket as well as a cap full of super thrive.
I think I'll go outside right now and feed my plants!
