A lot of gardeners grow hydrangeas and this time of year they begin to ask questions about how and when to prune these plants.
First, we need to consider the different species of hydrangea that are available in this area. If you have a Hydrangea mycrophylla, Big Leaf or French Hydrangea as they are commonly called, these plants flower largely on old wood or stems that were produced last season. Consequently, when we have a spring freeze in April like in 2007, these plants won’t flower.
