There seems to be this general rule that you can’t trim roses during the year. This is supposedly saved only for “pruning time”. Not true, really.
Roses, like all plants, can be trimmed all season long to keep them from getting overgrown and messy. In fact, doing so keeps new growth coming and will help the re-bloom
I find the best time to do this is right after a bloom flush. What’s a bloom flush? This is any point during the season when your roses are covered in blooms all at once. If you live in an area with a true winter there is the spring bloom flush, usually another one shortly after and then a nice fall bloom flush.
I don’t advise trimming after the fall bloom flush because we want to get the roses ready for winter. For more on that check out our section on Winter Care under the care menu.
I did a little video with some tips on how to groom roses during the growing season. Enjoy!
