How do you prune hydrangeas in Northern California?
When should I prune my hydrangea in Northern California?

How do you prune a hydrangea bush?
To get bigger flowers, cut them all the way back
In late winter or early spring, these shrubs can be cut all the way back to the ground. Smooth hydrangeas will produce much larger blooms if pruned hard like this each year, but many gardeners opt for smaller blooms on sturdier stems.

If it’s blue, or blooms in summer
Most of the other hydrangeas should be pruned in summer, once they have finished blooming. Most of these bloom on what’s called “old wood” — growth from the year before. If you prune them in early spring, you risk cuting off the dormant flower buds.
How can I tell if my hydrangea blooms on old or new wood?
Old wood is quite simply, last year’s wood. Hydrangeas that bloom on old wood set their flower buds in late summer on stalks that have been on the plant since the previous year. Hydrangeas that bloom on old wood include the mophead, bigleaf (macrophylla), lacecap and oakleaf varieties.
What month do hydrangeas flower?
The most popular types are mophead and lacecap. Hydrangea flower colours range from blue, white, red through to pink. If you plant more than one type in the garden you can plan for flowers from April to October. The foliage on some can be dramatic in autumn, most notable is Hydrangea quercifolia.
What side of the house do you plant hydrangeas?
It’s recommended to plant Hydrangeas on the side of the house that receives adequate light and coolness. Prepare the soil at the left side if much sunlight comes through that side of the house for Hydrangeas. And it’s not only hydrangeas that can live beside the house, other plants can as well.
Will hydrangeas grow back if cut down?
You can take a more relaxed attitude about pruning if you have hydrangeas that set flower buds on current season wood, like panicle and smooth hydrangeas. Even if you cut canes back to ground level during dormancy, the shrubs will grow back and produce blooms in spring.

Can hydrangeas survive a freeze?
Some hydrangeas can die because of freezing temperatures and cold winter winds that cause the plant to dry out. Cold weather can pull moisture from stems and leaves, causing dehydration. A late frost in early spring can damage new growth on hydrangeas that bloom on new wood.
Should I cut off deceased hydrangea blooms?
No need to worry – this is simply a sign that it’s time to remove the flowers, a process called deadheading. When you deadhead hydrangeas, you aren’t harming the plants at all. Removing the spent blooms triggers flowering shrubs to stop producing seeds and instead put their energy toward root and foliage development.
