Oakleaf Hydrangeas

Hydrangeas are the most popular flowering shrubs, and oakleaf Hydrangeas are a stunning variety. Oakleaf Hydrangeas get their name from their large, deeply lobed leaves, resembling an oak tree. The leaves are a beautiful deep green in the summer before turning a rich burgundy-red in the fall. And, of course, the show’s star is the clusters of white or pink flowers that appear in late spring or early summer. If you’re looking for a Hydrangea that will make a statement in your garden, an oakleaf variety is worth considering.

Climbing Hydrangeas

Climbing Hydrangeas are a type of Hydrangea plant specifically grown to climb up walls, trellises, and other structures. While they can technically be left to grow independently, pruning and training climbing Hydrangeas will result in a more aesthetically pleasing plant. Climbing Hydrangeas are relatively easy to care for. They prefer partial sun to full shade and moist, well-drained soil. Once established, they are drought tolerant. It is important to water regularly during the first growing season to encourage root development. Fertilize in early spring with a balanced fertilizer.

Why and When to Prune Your Hydrangeas?

Pruning Hydrangeas is important to keep these beautiful plants healthy and vigorous. There are a few different reasons why you would want to prune your Hydrangeas, and the best time to do so depends on the type of plant. Hydrangeas bloom on new wood (such as panicle and smooth Hydrangeas) and should be pruned in late winter or early spring before new growth begins. This will ensure the plant has plenty of time to produce new flowers for the season. Pruning too late in the season can also reduce the number of blooms for next year.

On the other hand, Hydrangeas that bloom on old wood (like bigleaf and oakleaf Hydrangeas) should only be pruned after they have flowered. Pruning before they flower can result in fewer or no blooms. If you wait until after they flower, you can remove dead or damaged branches and branches crossing or rubbing against each other. Pruning Hydrangeas is important to maintaining healthy plants and keeping them looking their best.

By carefully considering which variety you have, when to prune it, and how to do it properly, you can ensure that your Hydrangea will remain in good condition for years. With a little knowledge and care, you can enjoy the beauty of these spectacular plants without any headaches. These plants are relatively low-maintenance, so you don’t need to be overly aggressive with your pruning.

Tips to Prune Bigleaf Hydrangea

Deadhead Spent Flowers

Regularly removing spent flowers is important to keep your bigleaf Hydrangea blooming at its best. This process, called deadheading, not only encourages new growth and more flowers but also helps to keep the plant tidy and looking its best. Cut off the stem below the flower head with pruning shears to deadhead spent flowers.

You can either dispose of the stem or leave it on the ground near the base of the plant, where it will eventually decompose and provide nutrients for the roots. After deadheading, look at your plant’s overall shape and prune any stray or leggy stems to promote fullness and encourage new growth.

Prune Away Dead and Weak Stems

If your bigleaf Hydrangea looks a little worse for wear, it may be time to give it a good pruning. Pruning helps to encourage new growth and can also help to shape the plant. When pruning, be sure to remove any dead or weak stems. These stems will not produce new growth and can harm the plant if left in place.

Prune for Size

Pruning bigleaf Hydrangea is best done in late winter or early spring before new growth begins. You can prune to reduce the plant’s size, remove damaged or diseased stems, or shape the plant. When pruning to reduce the size, cut back all stems by one-third to one-half their length.

Tips to Prune Smooth Hydrangea

Remove Dead or Injured Branches

If you notice any dead or injured branches on your smooth Hydrangea, removing them as soon as possible is important. Dead branches can harbor pests and diseases that can spread to other parts of the plant, and injured branches are more likely to break off and fall, which could damage the rest of the plant. To remove a dead or injured branch, use sharp pruning shears to make a clean cut above a healthy bud or branch. Cut the branch back to the main stem if no healthy buds or branches are nearby.

Trim for Shape

If you want to achieve a certain shape with your smooth Hydrangea, then you must trim it. The best time to do this is in late summer or early fall. Start by pruning away any dead or diseased wood. This will help improve air circulation and prevent the spread of disease. Next, cut back any shoots that are growing out of bounds. Up to two-thirds of their length can trim back. Finally, prune away any straggly or leggy growth. This will help improve the overall shape and appearance of your plant.

Prune Hard for Large Flowers

You should prune your smooth Hydrangea several times yearly to keep it looking its best. First, remove any dead or diseased stems. Next, cut back the remaining stems by one-third to one-half their length. Be sure to make your cuts at an angle so that water can drain off easily. Finally, thin out the center of the plant to promote air circulation and prevent disease.

Tips to Prune Panicle (Peegee) Hydrangea

Deadhead Spent Flowers

First, to deadhead spent flowers on a panicle Hydrangea, identify the stems that have finished blooming. These will be the stems that are brown and woody in appearance. Using pruning shears, cut the stem to a point just above where new growth emerges. Repeat this process throughout the season as needed to keep your plant looking its best.

Prune Lightly to Maintain the Shape

When pruning panicle Hydrangeas, it’s best to err on the side of caution. These shrubs are vigorous growers and can quickly become overgrown if improperly maintained. Prune lightly after each bloom cycle to keep your panicle Hydrangea in shape. This will encourage new growth and help to keep the shrub from becoming too leggy.

Do Hard Pruning in Late Winter

When pruning panicle Hydrangeas, the best time is late winter or early spring. This will give the plant ample time to recover from damage during pruning and encourage new growth. When pruning, be sure to remove any dead or dying branches first. Then, cut back any remaining branches by about one-third of their total length. This will help promote fresh growth and prevent the plant from becoming too leggy.

Remove Dead Stems in Early Spring

Removing dead or dying stems in early spring is essential to keeping your panicle Hydrangea healthy and looking its best. Doing this will also help encourage new growth. To remove dead or dying stems, use sharp pruning shears to cut them back to the point where they branch off from a live stem. Make your cuts at a 45-degree angle so that water can drain away from the cuts.

Prune for Shape

To prune for shape, first identify the main stems of the plant. These are the thickest, longest branches that extend upwards from the base of the plant. Cut away any smaller branches that grow from the main stems. Next, identify any crossed or rubbing branches and prune these away as well. Finally, cut away any branches growing towards the center of the plant.

Tips to Prune Climbing Hydrangeas

Prune to Control Size

To control the size of climbing Hydrangeas, prune them annually in late winter or early spring. Cut back the previous year’s growth by one-third to one-half, removing any weak or spindly stems.

Special Pruning to Rejuvenate a Neglected Plant

If your climbing Hydrangea looks neglected, you can rejuvenate it with special pruning. First, remove any dead or diseased wood. Then, cut back all the stems to about 6-12 inches from the ground. This may seem drastic, but the plant will quickly return with new growth. Finally, thin out any crowded or crossing stems to allow light and air to reach the center of the plant.

Tips to Prune Oakleaf Hydrangeas

Prune Out Winter Dieback

As soon as the blooms fade on your oakleaf Hydrangea, it’s time to do some pruning. First, remove any stems that are dead, dying, or diseased. Cut these stems back to healthy wood. Next, thin out the plant by removing some of the older stems down to the ground. This will boost new growth and prevent the plant from becoming too dense and top-heavy. Finally, cut back any long or wayward stems to tidy up the plant and promote air circulation.

Prune for Shape

Remove any dead, damaged, or diseased wood to prune for shape. Next, remove any crossing or rubbing branches. Finally, cut back the remaining branches to the desired length and shape.
