When Is The Best Time To Cut Back Knockout Roses


I am at this stage, growing 6 of the knockout roses – 2 are in 6ft pots on my patio. The other 4 are in 8ft pots on their own plot. They have been here for over 3 years now and I don’t think it is time to cut them back just yet!

I do go out there occasionally to see how they are doing, but mostly I leave them be 🙂
