Double Knockout Roses, What to Do Now
My double knockouts roses were not pruned last year. Now have branches that are full bloom laying over on ground. What do I need to do?
Wait for them to be done blooming, then go ahead and prune things back. The new growth that comes forth from the pruned back areas will bring with it new blooms. Give them some good rose food and water it in well, rinse down the foliage too, after pruning them back. Don't do the rinseing down during the heat of the day. Best to do all of the above either early in the morning or in the early evening when the temps start to cool down.
