Hi everyone,
I have looked up my zipcode in Highland, Mi (48356) and see that May 16 is recommended as a planting time. But I don't see a recommendation for when to prune my Karl Foerster grasses, hybrid tea roses, Sally Holmes rose, and other perennials. If anyone could please offer advice on this, I'd greatly appreciate your help.
Mahalo
and aloha,
