Can You Trim Rhododendrons With a Hedge Trimmer

It is not a good idea to trim rhododendrons with a hedge trimmer. Instead, you may use a chainsaw, hand saw, or a pruning shear to trim those heavy branches off of your overgrown rhododendron.

Rhododendrons have thick branches, so using a hedge trimmer on them would not be a wise decision considering that it is not designed for use on thick branches.

You can easily trim your rhododendrons with the proper tools, and the good part is that they don’t need pruning on a regular basis. They require very little maintenance and adapt well to light trimming.

However, if your rhododendrons have outgrown their space and you haven’t trimmed them in a long time, you need to go with hard pruning rhododendrons.

Along with trimming, rhododendrons also need shaping and rejuvenation, which you should take care of as you do so.

Why Is It Important to Trim Rhododendrons

It is important to trim rhododendrons for their better quality. Rhododendrons must have a few of their flower branches removed from the shrub once the blooming has stopped. If you don’t do so, the dead flowers will stay there, diminishing blooming the following year.

Rhododendrons have a tendency to grow gangly branches that are out of place and may simply look neglected; thus, you may trim them to give them a nice semi-round shape.

Rhododendrons frequently grow too big and might appear dull. A rhododendron can regain its youthful appearance by being cut back when it becomes overgrown.

They benefit from pruning because it keeps them in a more natural shape and promotes a healthy recovery.

Additionally, pruning enhances the placement and quality of the remaining flowers on the shrub.

Which Season Is Ideal for Rhododendron Pruning

Can I prune rhododendrons in summer? you may wonder. Well, don’t do that! Late winter is the best time to prune rhododendrons.

Rhododendrons should be pruned anytime between the first snow in the fall and the last snow in the spring. It will enable them to recuperate fast and generate new growth.

Rhododendrons must be pruned as soon as they stop blooming and begin to fade away in order to produce healthy blooms the next season.

Late winter is the ideal time because if you wait too long, new flower buds will start to grow, and you don’t want to remove the potential bloom for the next season while pruning.

Is trimming azaleas in late summer okay? That is also a definite no. Azalea pruning should be done by mid-summer.

Make sure to avoid pruning rhododendrons after their spring growth because this is the time when the new leaves are still hardening off, and doing so will probably limit blooming.

How to Prune Overgrown Azaleas

Now that we’re talking about pruning azaleas, which are flowering shrubs in the genus of rhododendrons, let me first clarify that it is not at all a difficult task or anything that demands extra effort.

When pruning rhododendrons, you have three methods to choose from. Let’s go over each of them.
Maintenance pruning is the easiest type of pruning and only involves trimming off any dead or dying parts of your rhododendrons.

If you have dead leaves that look yellow or brown and dead branches that are crispy, then it’s a sign that you must remove them from your rhododendron. They not only look bad but also take off all the energy.

Removing them will help the other thriving plants grow better, and let me tell you how that happens.

Maintenance Pruning 

Maintenance pruning is the easiest type of pruning and only entails clipping off any dead parts of your rhododendron.

If you notice dead leaves that are yellow or brown, as well as crispy dead branches, it is time to remove them from your rhododendron. They not only have a poor appearance but also drain all the energy.

Removing them will help the other growing flowers grow faster, and let me explain how.

The dead flower clusters produce seeds, which consume vital energy and leave little for the living and blooming flowers. Therefore, it’s important to cut them off.

Use pruning shears to remove the dead flower clusters from your rhododendron about half an inch above the new growth.

When you see that your rhododendron needs maintenance pruning, only do it once a year and you’ll be set for the rest of the year!

Shaping

You may be thinking, ‘my rhododendron is too big and blocks the entire view.’ I do, however, have a solution for you. Shape it!

When your rhododendron is completely overgrown and you want to regulate its size, whether it be all spread out and you want it to be uniform in a spot or you want it to grow in a specific direction, shaping will go in your favor.

All you have to do is remove the parts of your rhododendron that need to be small and leave the parts, which are all healthy and have a great, big appearance.

You must make your cut directly above the leaf whorl. Make a ¼ inch cut above the topmost leaf in the cluster and repeat until the desired length is reached.

However, you must keep in mind that you should not cut more than one-third of the plant.

Additionally, shaping also only needs to be done once a year. It will make your rhododendron seem better and promote more branches at its growth points.

Rejuvenation

Can you keep rhododendrons small? Of course, you can, and this rejuvenation method is just what you need to do so.

If your rhododendron has become overgrown and unattractive and you no longer want it that way, rejuvenation pruning entails cutting back the main branches of the plant’s framework.

You’ll need to cut the main branches that grow from the rhododendron’s crown. By removing them, old stems that were previously leafless will begin to grow again. Over time, this new growth will develop into a new framework that you can obviously shape however you choose.

Another way of rejuvenation entails cutting the entire rhododendron to a height of no more than six inches from the ground.

However, you should be aware that not all rhododendrons will survive this treatment, so you should first determine if yours will or won’t.

To make sure, you should only remove one of the main branches and lightly prune the remaining branches. If it responds well, you cut all of the other branches as well.

Knowing how thick the main branches are, a chainsaw will be required, which is certainly the best tool for the job.

Pruning

Now that you’ve decided which method to use, it’s time to select the right tool for the job.

A chainsaw will come in handy if you need to cut through large, woody branches when working on an overgrown rhododendron.

Otherwise, a hand saw or pruning shears would work perfectly for smaller branches.

You must cut the branches uniformly and evenly with the tool that you are using. Do not cause the branches to bend or break.

Once you’ve finished trimming, sweep away any fallen leaves or branches on the ground to keep your rhododendron and yard looking pleasant.
