Tree Pruning vs. Trimming: Which Is Right For Your Trees and Shrubs?

The rose bush in your garden has drooping flower buds, while the beloved maple tree in the backyard is starting to scrape against the house after a couple of years of rapid growth. If you want to remedy these issues, how do you know whether to choose between pruning versus trimming your trees and shrubs? 

While these terms are sometimes used interchangeably and are similar, there’s a right time to prune and a right time to trim your plants. Here’s how to know which method will work best for your blooms.

Tree Pruning vs. Tree Trimming: Key Differences

So, is pruning the same as trimming? There is a difference between pruning and trimming. Pruning involves cutting diseased and dead branches and even unnecessary branches that need to be removed to help promote growth. 

Trimming trees involves cutting the branches all over to manage unwanted growth and make them look crisp and well-maintained. However, properly trimming trees can help stimulate growth as well. Whether you are pruning or trimming, it’s essential to do it correctly to avoid killing the tree. 

What Is Tree Pruning?

While you may have heard some pro-planters at the gardening store discuss their pruning methods, you may not know what pruning is exactly. Again, pruning refers to cutting off unnecessary or unhealthy branches from a tree or shrub. 

Tree branches that are broken, loose, riddled with pests or disease, or otherwise unhealthy will need to be removed. But you may also want to prune some plants, like boxwoods, junipers, or birch trees, to thin out their branches and promote growth.

Pruning is often necessary when plants have unhealthy branches that can spread disease or pests to other parts of the plant. You have to make time as soon as possible to handle pruning in these cases or risk plant die-off.

Pros of Tree Pruning

Pruning is an essential task for trees and shrubs. While you can use it cosmetically to thin out a plant or boost growth overall, it is also crucial for keeping your trees or shrubs healthy if they catch a disease or become a host for pesky pests.

• Woundwood: Pruning unhealthy branches encourages the area to grow woundwood, or new wood growth over wounds, to prevent pests or diseases from spreading throughout the plant.

• Growth: Pruning can help stimulate growth throughout the plant by redirecting plant hormones from growing longer branches to growing new ones for a fuller, bushier look.

• Small area to prune: With pruning, you are likely only working in a small area rather than trimming all over the plant. This can make the job easier and faster to complete than trimming.

Cons of Tree Pruning

Pruning isn’t always a good thing, though. Over-pruning can leave plants looking bare or promote growth in unwanted areas of the plant. Knowing when to prune is also essential since pruning in extreme weather can stress out a tree or plant.

• Undesired growth: While stimulating growth can be good, it can also encourage a tree or brush to sprout many more branches that change the look of the plant or require more upkeep.

• Tree injury potential: If you prune in colder weather or during extreme temperature changes, this task can stress the tree and cause it to crack.

• Timing is important: Although pruning is urgent to minimize pest or disease spread, pruning outside of the plant’s growing season can make it harder to recover.

What Is Tree Trimming?

What is tree trimming, anyway? Just like you trim your hair to maintain its shape and luster, trimming a tree can keep it looking its best. Trimming trees involves cutting the branches shorter all over. 

This task may be for aesthetic reasons for trees and other plants as well. For instance, keeping a shrub or bush looking neat and tidy or keeping a plant’s branches from rubbing against the side of the house or shed. 

Pros of Tree Trimming

Trimming offers many benefits to your trees and plants, mainly to keep them looking prim and proper rather than wild and unruly. Trimming branches can also help keep the plant healthy with better nutrient allocation throughout the tree or shrub.

• Curb appeal: Messy trees and shrubs may look natural and rustic in some landscapes, but many homeowners prefer the tidy look of trimmed plants.

• Natural light: By trimming back trees and shrubs, more natural light from the sun can reach other parts of the plants and ground below.

• Improves growth: Trimming young plants regularly can help boost their growth as they mature by making it easier for all plant parts to access nutrients.

Cons of Tree Trimming

Trimming usually becomes problematic when you trim too often or trim away too much of the plant in one session. Excess trimming can stunt growth or cause injury to the plant, so make sure not to go overboard when you break out the trimmers or saw.

• Plant damage: Trimming more than 20% of the foliage in a session and trimming too often can damage the plant.

• Larger area to trim: It’s not likely you’ll just trim down a branch or two. Trimming involves cutting down branches around the plant until you reach the look you want.

• Dangerous: Pruning and trimming are both dangerous because incorrect pruning or trimming can damage the plant stem or bark, but it can be hazardous to trim the lengthy branches of a tall tree on your own because you could fall.

Pruning vs. Cutting

Now that you know what tree pruning is and what tree trimming is, plus how these methods work for other plants in your yard, you can compare them directly to find which option will work best for your yard and garden.

Pruning is mainly used for plant health and safety while trimming usually focuses on the plant’s appearance. Use this trim vs. prune comparison breakdown to help you choose the proper method:

Appearance: Trimming

Trimming is the top choice if you want your shrubs to be perfect squares or circles or your tree branches all to reach the same length. 

Pruning can offer some aesthetic benefits as you thin out a plant, but trimming is the standard method for shaping a plant or changing or maintaining its appearance.

Best for appearance: trimming

Price: Depends on Circumstance

Pruning trees and shrubs costs about $200 to $800, while trimming trees costs about $200 to $760 per session. The rates are similar but can vary based on many factors. Trimming tall trees may cost more than pruning small trees or shrubs, while pruning can cost more if it is an emergency to eliminate pests or diseases. 

You may also need to schedule trimming services more often, about twice per year, compared to pruning, which happens once per growing season or as needed for plant health reasons.

Best for price: Both, depending on the plant and circumstances

DIY-ability: Pruning

In most cases, consider hiring a tree service near you to prune and trim your plants. Pruning requires a skilled hand to prevent damaging the plant or causing pests and diseases to spread further. Plus a pro can identify how much the pest or disease has impacted the rest of the plant. 

Trimming can be especially dangerous for taller, larger trees. Pruning usually requires just a set of shears, though, and involves working on smaller sections of the plant, so it can be easier for DIYers.

Best for ease of DIYing: Pruning

Maintenance: Pruning

Plants that overgrow and require regular pruning usually only need tending once per growing season. Otherwise, you may only need to prune when you notice signs of disease or pests. Many plants benefit from trimming about twice yearly or more if the branches and foliage grow rapidly.

Best for maintaining: pruning

Sustainability: Both

Keeping trees, shrubs, bushes, and other plants healthy involves TLC throughout the year. Pruning away unhealthy or loose branches and trimming branches can promote plant health. Healthy trees and shrubs provide safe, reliable habitats for local bugs, birds, and other critters to call home.

Best for sustainability: Both
