I am new to this forum. I bought a Quick Fire Hydrangea from UBC garden centre last weekend. It is 2005 new type of hydrangea introduced to Canada. I am very excited about it. I have two questions. (1) It supposed to bloom earlier than other types, but it didn't show any sign of blooming. Why? (2) It has a single strong stem at 3' tall and others are 2' and lower. It's not very bushy. I can see a sign of pruning before but I don't know why this tall branch remained. Should I prune this tall branch? How and when. Please give your advice. Is there anyone have any exprience about this plant?
