I just moved into my first home 3 weeks ago and have turned my attention to the gardens. I was fortunate enough to inherit a very well established garden, but it really needs some editing and reorganization. My favourite flowering plants in the front are 2 hydrangeas and 2 small rose bushes. I have read that it's best to move these plants in the fall, but what would happen if I tried to carefully move them now? They are quite small (approximately 2.5 feet tall) and would certainly get more light and room if moved out of the overgrown part of my yard. I don't mind losing a few flowers in the short term, but I certainly don't want to kill anything permanently.
Also, is there a rule of thumb for how small a shrub should be for transplanting? I plan on moving some this fall, but I'm not sure how big is too big.
Any advice out there for a novice gardener?
Thanks so much for your help and wisdom!
