My perennial garden has grown out of control and is hiding some plants. I have never split perennials before and need some step by step directions. I am an amateur and nervous about plants dying. My email is. kmarthy50@gmail.com Thanks!
Generally perennials should be divided in the fall or early spring. Dividing now in summer when they are in the middle of their growing season isn’t ideal since the shock is much greater. Here’s a link to a blog post about the project although it is an older post and I would now use Bio-tone starter food rather than the Bone Meal. https://blog.timesunion.com/gardening/dig-in-and-divide/6447/ You could google “dividing irises” for instance to get more specific suggestions for each plant. It isn’t difficult and is a great fall project. Best of all you’ll have extra plants to use in other places or share with friends
