Delphinium & Lupin
My delphiniums have been battered by the recent bad weather and I want to cut down the flower spikes on the worst affected. Do I cut them right to the ground or just below where the flower starts?
I also want to do the same with the lupins (I'm not that bothered about letting them produce seed) Is it the same process?
I pressume I leave the foiliage to die down naturally on both plants????
Many thanks Anna
