Summer Blooming Perennials – When Best To Fertilize

Q: When it best to fertilize my summer blooming perennials?

A: If you use a liquid fertilizer, fertilize one time at planting, once six weeks later, and another time six weeks after that. Of course a timed-release granular fertilizer, like Osmocote, can last up to six months before it stops supplying nutrients to your plants.
