Bigleaf hydrangeas are one of the most common types of hydrangeas found in North America. They can grow quite large, so it's essential to prune them regularly to maintain their shape and promote healthy growth.

Bigleaf hydrangeas form their flower buds on old wood, which means that next summer's buds are already present on the branches in fall and winter. This is crucial to keep in mind when pruning, as cutting off these buds can remove all the blooms for the season.

Pruning bigleaf hydrangeas in the wrong way can be disappointing, as it can remove all the flowers for the season. However, pruning them correctly can ensure a beautiful display of blooms come spring.

You can safely prune bigleaf hydrangeas after mid-February, when freezing temperatures are often behind us. However, check the forecast and watch for cold warnings.

To prune your bigleaf hydrangea, choose a dry, mild day and begin by thinning to reduce congestion in the shrubs. Remove the most weak and spindly stems, and any that are awkwardly placed. You can take out up to a third of the stems.

Watch for remaining stems bearing pairs of fat, green buds below the old, faded flowers from last year. Those buds will develop into flowering growth. Make cuts immediately above the uppermost pair of substantial buds on a stem.

If you live in an area with a heavy snow load or prefer a tidier look in winter, prune your hydrangea in late fall to early winter. This will allow you to enjoy the look of dried flower heads in your garden in the wintertime.

Bigleaf hydrangeas typically bloom on old wood, meaning the flower buds are on the growth produced the previous season. If you prune them before they flower, you will be removing the flower buds.

Pruning bigleaf hydrangea for winter requires a thoughtful approach to promote healthy growth and prevent damage from cold temperatures. Prune the plant in late winter or early spring, around late February to early March, when it's still dormant.

Remove any dead, diseased, or damaged branches, cutting them off at the base to prevent the spread of disease. This will also help maintain the plant's overall shape and encourage new growth.

By pruning your bigleaf hydrangea in the right season, you'll be rewarded with a beautiful, thriving plant come springtime.

Pruning hydrangeas requires some finesse, especially if you're not sure which type you have.

Hydrangeas that bloom on old wood, like bigleaf, oakleaf, and mountain hydrangeas, should only be pruned to remove dead branches in the spring.

For new wood bloomers, like smooth and panicle hydrangeas, you can prune in late fall or early spring, but be careful not to remove too much of the plant.

Pruning too much of a new wood bloomer can remove the sturdy framework that keeps the plant standing upright, so it's best to prune no more than one-third of the plant.

To determine how much to prune, consider the plant's size: if your hydrangea is six feet tall, you can safely prune up to two feet off the top and sides.

When pruning, make your cut just above a set of large, healthy leaves, and only remove dead or broken branches.
