When and how often should I feed my perennials?

By Keith Funk


A:  My first application of plant food on my perennials is in early April.  I prefer a granular fertilizer with an analysis of 10-5-5 or something in that ballpark. that I can apply with a spreader and then water in thoroughly.  Any reputable brand of organic flower garden fertilizer will do.  Just follow label directions and repeat as often as recommended.  I feed monthly from April through September.  I’ve even used organic lawn food on my perennials in a pinch because I know organics are slow-release and won’t burn the foliage.
