Cutting back hardy geraniums: Best time to do so?
When is the best/right time to cut back hardy geraniums so that they're ready for the new season?
I trimmed them of their dead flowers and brown messy foliage after flowering late last summer, and was planning on chopping them back hard once the rest of the foliage browned and started dying off, but the remaining foliage stayed looking healthy and green all winter!
It's still in good shape now and is kind of helping the border look a bit more pleasant and green rather than there just being bare brown soil, but should I cut it back hard to the ground before spring anyway? (I.e. will it not grow/flower as well if I leave it as it is? Will it block/stunt the growth of other nearby hardy new spring shoots if I leave it as it is?)
If you do recommend chopping back hard, when is the optimum time to do so (now? early spring? ideally before now?)
