70-Year-Old Hydrangea Tree
My grandmother used to live next to us and I always remember her hydrangea tree. It's still alive today and has to be at least 70 or more by now. Parts have died out, but it continues to bloom. Does anyone know how long they live? Also, should I fertilize it? If so, when and with what?
PS~I have taken some slips. I hope to winter them over on our enclosed porch. The heat does come on at times when our furnace runs and it's quite warm, but for only a brief amount of time. The rest of the time (90%) it's quite cold out there. Does this sound like a good place for them or not? I'm new to this but quite interested!
