Question From: West Bloomfield Township, Michigan, United States
Q: Hi Nancy, How do you transplant Knockout roses? When? Do I prune beforehand? Etc. Thanks, Kerry
A: Wait until the plant is dormant and dropped it's leaves. Dig the new hole first and amend the dug soil with compost and composted pine bark. I prefer Organimax compost and Fafard soil conditioner. Dig the rose and and replant it. The rose should be a little deeper than it was originally planted. Mulch it with 3 to 4 inches of organic mulch and water it well. If it doesn't rain water it once a week until the soil freezes. Prune it back to a size you can handle just before you plant it. Fertilize it after its first round of blooms in June. Best And Happy Yardening, Nancy. ps. English Gardens carries Organimax.
