The Q&A Archives: Pruning Grandiflora Roses

Question: When is the best time to prune grandiflora roses? How? Why don't I ever see much about grandiflora? Is it a wise selection? Valerie Dillon Pataskala, OH

Answer: Prune grandiflora roses in much the same way as you would a hybrid tea rose. First of all, in early spring, look for any winter injury and prune back the branch to healthy wood. Head back small branches so that all remaining branches are approximately the diameter of a pencil. Remove any branches that cross or rub. Make pruning cuts just above a bud, being careful not to damage the bud. Perhaps the reason you don't see much about grandifloras is because they are closely related to hybrid teas and thus intermixed with them in catalogs and articles. The main difference between the two is that hybrid teas bear large flowers individually on long stems, while grandiflora blooms are borne in clusters.
