Should I cut down my hydrangea for winter?

Answered by Ricardo McCardle

As an expert, I’m happy to provide you with some guidance on whether or not you should cut down your hydrangea for winter. The answer to this question depends on the specific type of hydrangea you have and the region in which you live.

1. Determine the type of hydrangea: Hydrangeas can be categorized into two main types – those that bloom on old wood and those that bloom on new wood. This distinction is important when deciding whether or not to prune your hydrangea for winter.

– Hydrangeas that bloom on old wood: These hydrangeas, such as the mophead (Hydrangea macrophylla) or lacecap (Hydrangea serrata) varieties, produce flower buds on the previous year’s growth. Pruning these hydrangeas in late winter or early spring would remove the flower buds and result in little to no blooming in the upcoming season. It’s best to avoid pruning these hydrangeas in winter.

– Hydrangeas that bloom on new wood: These hydrangeas, like the smooth hydrangea (Hydrangea arborescens) or panicle hydrangea (Hydrangea paniculata) varieties, develop flower buds on the current season’s growth. Pruning these hydrangeas in late winter or early spring would not affect the blooming potential for the upcoming season. It’s generally safe to prune these hydrangeas in winter if desired.

2. Consider your climate and region: Another important factor to consider is the climate in which you live. Hydrangeas in colder regions may benefit from some winter protection, while those in milder climates may not require as much attention.

– Cold regions: If you live in an area with harsh winters, it’s a good idea to provide some winter protection for your hydrangea. This can include mulching around the base of the plant with a layer of organic material, such as straw or leaves, to insulate the roots. Additionally, you can consider building a simple burlap windbreak around the plant to protect it from strong winds and cold temperatures.

– Mild regions: In milder climates, where temperatures rarely dip below freezing, winter protection may not be as crucial. However, if you experience occasional frost or freeze events, it’s still a good idea to monitor the weather and cover your hydrangea temporarily during these periods.

3. Assess the overall health and size of the hydrangea: Pruning can also be done for maintenance purposes, even if it’s not necessary for winter survival. If your hydrangea has become overgrown or unruly, late winter or early spring is a suitable time to prune it back. However, be cautious not to remove too much of the plant, as this can reduce blooming potential for the upcoming season.

Whether or not you should cut down your hydrangea for winter depends on the type of hydrangea, your climate, and your specific goals for the plant. If you have a hydrangea that blooms on old wood, it’s generally best to avoid pruning it in winter to preserve the flower buds. However, if you have a hydrangea that blooms on new wood or if you want to perform maintenance pruning, late winter or early spring is a suitable time. Additionally, consider providing winter protection if you live in a region with harsh winters.
