Hello, I'm new to this forum, but not to DG. I've been having a Hydrangea plant for > 6 years and it remains in a pot. I've changed the top soil 2-3 times and entirely, once I think. Since this needs some shade, I've not put it in the ground in a permanent place because it needed to be moved into a shady area in summer. Mysore is in the plains and these hydrangeas are found in the cooler hills some 100 miles away from Mysore. Those spent blooms... are they to be removed off?
