I water once a week, fertilize once a month with 10-10-10. Speaking of fertilizing hoya, all mine got a dose of Epsom salts [1 teaspoon/gallon]. This particular plant is always indoors, and about 9 foot, hit the ceiling and wound its way back down again. Question - how often do I fertilize with ES? I just did this once.
Hoya not blooming like it usually does.
