conditions for hydrangea
Explain something to me - what pH or conditions do hydrangeas like? I have a large H by my driveway in a dry , alkaline location with a lot of underlying limestone from the driveway bed. For several yrs it's look weak, then this yr, when we had at least a month long drought, it has looked great throwing out a ton of leaves. The deer browse it every winter and I was going to dig it out this summer but left it alone because it looked just fine - even putting enormous flowers out from twigs the deer missed.
I'm transplanting another huge hydrangea into an area with more sun but the soil is very heavy clay and even with amendment it will be heavy. Is it going to like that?
Since azaleas, pulmonaria, ferns and hosta are so happy there, I'm pretty sure the soil leans to the acid altho I haven't tested it.
