|Knockout roses can be pruned throughout the growing season to keep them neat and compact. You can wait until they go dormant (after your first frost) and prune them back by about one third. Then, after their first flush of flowers you can prune them back by one third again. Pruning in this manner will encourage a thick and bushy shrub without retarding the natural blooming cycle. Enjoy!
