I planted beautiful Becky Shasta Daisies last year in front of my Dahlias. I've decided after this season, no more Dahlias, but due to the height of my daisies I will need to move them to a different location. When is the best time to do so? Also, what is the safest way to move them so I don't kill them and they suffer the least amount of transplant shock? I don't know a thing about transplanting flowers and I can't seem to find anything specific about Shasta Daisies but I love them and want to keep them, can anyone please help?
