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
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.
