When do you trim hydrangeas?
i am having trouble pruning my hydrangeas so they bloom a lot the following year. When is the best time to prune?

It depends on what species of Hydrangea you are growing. The most common mop-head Hydrangeas need to be pruned in summer but before August 1st as they are setting flower buds for next year already.
Here is a list of the species and when to prune
I hope this helps.
