|Can knock out roses be cut way back to keep them from getting too big? If they can when should it be done and are they as picky as regular roses as far as how to cut them?

|Knock Out roses can take just about any amount of pruning. I usually cut mine back by about one half in the winter/early spring and then prune back any extra long stems and branches throughout the growing season. While pruning can help keep the plants smaller, you won't be able to keep them too low or they won't flower. Plan on pruning them back by one half or one third twice a year (late winter/early spring and again in mid-summer) and you should be able to keep them neat and tidy and still full of flowers.
