Prune Bigleaf Hydrangea for Bigger and More Beautiful Blooms

To get bigger and more beautiful blooms from your bigleaf hydrangea, pruning is key. Prune your bigleaf hydrangea in late winter or early spring, before new growth begins.

Bigleaf hydrangeas can grow quite large, so pruning them regularly will help keep them in check and encourage more blooms. Prune them back to about one-third of their height to promote new growth.

Pruning also helps to control the size of your blooms. Bigleaf hydrangeas produce blue or pink flowers, depending on the soil pH, and pruning can affect the color of the blooms.

Pruning bigleaf hydrangeas is a delicate process, and timing is everything. Prune your bigleaf hydrangea when the flowers begin to fade.

The best time to prune is just after the flowers have bloomed, giving the shrub ample time to set new growth and harden off before winter. Avoid pruning after August 1, as this will prevent flower buds from forming for the following season.

Prune out flower heads and head back other shoots as necessary to encourage branching and fullness. Make your cut just above a set of large, healthy leaves. If a branch is broken or dead, remove it completely.

Here are some general guidelines for pruning:

Pruning too much can also remove too much foliage, leaving the plant without enough leaves to make food to support the root system.

Do You Prune at the Right Time?

You should prune bigleaf hydrangeas just after they're done blooming. This allows the shrub to set new growth and harden off before winter.

Pruning too early can be disastrous, especially if your hydrangea isn't blooming. This is often the culprit behind poor blooming.

Many newer varieties of hydrangeas produce buds on both old and new wood, so pruning too early won't completely stop the show, but it will reduce the number of blooms.

Pruning at the right time will help your bigleaf hydrangea thrive and produce beautiful blooms.

Pruning can seem intimidating, but having the right tools makes all the difference. You only need a few basic tools to get started.

For bigleaf hydrangeas, you'll need hand pruners and a pair of loppers. These will help you make precise cuts and reach deeper into the shrub.

It's also a good idea to wear some safety glasses, as it's easy to poke your eye on a stem when trying to see into the shrub.

Avoid pruning after August 1, as this will prevent flower buds from forming in late summer. Sometimes, it's necessary to prune after a harsh winter to remove damaged foliage, but be aware that this will encourage vegetative growth at the expense of flowers.

Don't prune more than one-third of your hydrangea, as this can remove too much of the sturdy framework that keeps the plant standing upright. If you need to prune, make your cut just above a set of large, healthy leaves.

Pruning too much can also remove too much foliage, leaving the plant without enough leaves to make food to support the root system. If in doubt, don't prune – no hydrangea requires pruning to grow and bloom well.

Here's a rough guide to pruning your hydrangea:

Remember, it's always better to err on the side of caution and prune less than you think you need to. If a branch is broken or dead, it can be removed completely.

Deciding when to prune your bigleaf hydrangea is crucial for its health and blooms. Prune your hydrangea immediately after it finishes flowering, but if it blooms on old wood, it's best to prune in the spring.

Bigleaf hydrangeas that bloom on old wood, such as those that are not rebloomers, should be pruned only to remove dead branches in the spring. Examples of these types of hydrangeas include oakleaf hydrangeas, bigleaf hydrangeas that are not rebloomers, and mountain hydrangeas that are not rebloomers.

Here are some types of bigleaf hydrangeas that bloom on old wood and should be pruned in the spring:

Hydrangeas can be pruned in the fall or early spring, depending on the type. If you have hydrangeas that bloom on new wood, such as smooth hydrangeas and panicle hydrangeas, you can safely prune them in late fall or early spring.

For hydrangeas that bloom on old wood, like bigleaf, oakleaf, and climbing hydrangeas, it's best to prune them soon after the flowers have faded in late summer. This allows the shrub to produce new growth where next year's flower buds will form.

To determine which type of hydrangea you have, check the examples of hydrangeas that bloom exclusively on old wood or new wood. Some examples include:

By knowing the type of hydrangea you have, you can prune it at the right time to ensure optimal blooms.

Climbing hydrangeas are a type of woody vine that can grow quite vigorously, making them a great choice for covering trees or other supports.

They bloom on old wood, which means they don't require a lot of pruning except to control their size.

To keep your climbing hydrangea in check, you may need to do some hard pruning to set boundaries for the coming season.

It's worth noting that climbing hydrangeas can grow quite large, so regular pruning is a good idea to keep them from getting too out of hand.

If you do need to prune your climbing hydrangea, it's best to do it in the dormant season, when the plant is less active.

Bigleaf hydrangeas bloom on old wood, which means they produce flower buds during the later part of the summer season.

To ensure optimal blooms, prune your bigleaf hydrangea soon after the flowers have faded in late summer.

This timing allows the shrub to produce new growth where next year's flower buds will form, giving you the best chance at beautiful blooms.

Bigleaf hydrangeas, including lacecap and mophead varieties, produce flowers in blue, pink, and purple shades, and have thick, shiny leaves.

Their bloom color can be influenced by factors such as soil pH, but that's a topic for another time.

The mophead variety produces large, ball-shaped flower clusters, while the lacecap variety produces flat and delicate flower clusters.

If you want to control the bloom of your bigleaf hydrangea, you need to prune it at the right time.

Bigleaf hydrangeas that bloom on old wood should be pruned soon after the flowers have faded in late summer. This allows the shrub to produce new growth where next year's flower buds will form.

To determine if a stem is dead or alive, gently scratch each stem. If the bark comes off to reveal green, you're holding a live, able-to-flower branch. If the stem is brown underneath the bark, you've found an old stem that can be removed.

If you prune your bigleaf hydrangea too early, you'll remove the buds before they get a chance to bloom. This is especially true for bigleaf hydrangeas, including the popular lacecap and mophead varieties.

Examples of bigleaf hydrangeas that bloom exclusively on old wood include:

These varieties come in blue, pink, and purple shades, with thick, shiny leaves.

Pruning your bigleaf hydrangea is a delicate process, and making a few common mistakes can have a big impact on your plant's health and appearance.

Pruning your hydrangeas throughout the season to keep them shorter is a big no-no, as it can cut off the flower buds and reduce blooming.

You might be tempted to prune your hydrangea to reduce its height, but the truth is, it will just grow right back to its original size, or even larger, because the act of pruning stimulates new growth.

Transplanting your too-large hydrangea to a new spot in early spring is a much better option, and you can replace it with a variety that naturally stays shorter.
