• Mophead hydrangeas: These are the classic big, round blooms that come in shades of pink, blue, or white. Mopheads bloom on old wood, which means they set their buds for next year's flowers in the fall. You should prune mophead hydrangeas immediately after they finish blooming, usually in late summer or early fall.

• Lacecap hydrangeas: These look similar to mophead hydrangeas, but they have a flatter, more open bloom. Like mopheads, lacecaps also bloom on old wood, so you should prune them after they finish blooming.

• Panicle hydrangeas: These have elongated, cone-shaped blooms that come in white or pink. Unlike mopheads and lacecaps, panicle hydrangeas bloom on new wood, which means they set their buds in the spring. You can prune panicle hydrangeas in late winter or early spring before they to grow.

• Gloves: Wear gloves to protect your hands from thorns, scratches, and blisters.

How to Prune Leggy Hydrangeas

1. by removing any dead or damaged branches. Use your pruning shears or loppers to cut them back to healthy wood.

2. Next, remove any branches that are crossing or rubbing against each other. This will help improve air circulation and prevent disease.

3. If your hydrangea is getting too tall and spindly, you can cut it back by up to one-third of its height. Make the cut just above a node, where a leaf attaches to the stem.

4. If your hydrangea is spreading too wide and taking over your garden, you can also cut it back by up to one-third of its width. Cut back each branch to a bud facing outward, which will encourage new growth in that direction.

5. If you want to encourage more flowers, you can selectively prune back some of the older branches to encourage new growth. Cut back the oldest branches to the ground, leaving younger branches to take their place.

6. Finally, give your hydrangea a good overall shaping by removing any stray or unattractive branches. Step back and take a look at your plant from all angles to ensure it looks balanced and attractive.

Common Mistakes to Avoid When Pruning Leggy Hydrangeas

While pruning hydrangeas isn't rocket science, there are a few common mistakes that can lead to a less-than-ideal outcome. Here's what to avoid:

• Don't prune too late in the season: If you prune too late, you risk cutting off next year's flower buds. Stick to the timing guidelines we outlined earlier.

• Don't be too aggressive: While it's tempting to cut back as much as possible, remember that hydrangeas need some foliage to produce energy for next year's blooms. Don't remove more than one-third of the plant at once.

• Don't overlook the details: Make sure your tools are sharp and clean, and disinfect them between each cut if you're pruning diseased plants. Also, pay attention to the angle and location of each cut to ensure a clean, healthy wound.
