Trimming Redbud Tree: How To Prune Redbuds For Healthy Foliage (4 Steps)

Have you ever wondered, is trimming Redbud tree varieties necessary?

Well, Redbud trees are a delightful addition to any landscape, providing your garden with beautiful lavender or pink flowers in early spring before the leaves emerge.¹

Their gracefully arching branches and heart-shaped leaves, particularly in Eastern Redbud trees, also add greenery and ornamental value throughout summer.²

However, without trimming Redbud tree properly and occasionally,³ redbuds can become susceptible to disease and structural problems thereby losing the beauty that you love them for.

In this comprehensive guide on trimming Redbud tree, you will learn the key reasons for pruning redbuds, when and how to trim Redbud trees, the redbud trimming process based on tree size and age, tips on hiring an arborist or tree trimming service, and understand the desired results of trimming.

Trimming Redbud Tree: Signs Your Redbud Needs Pruning

Learning the right way to trim a Redbud tree can help you encourage lush foliage growth, remove diseased limbs, and sculpt an attractive form.

Monitor your redbuds for these signals that it might be time to start thinking about pruning them:³

• Excessive crossing/rubbing branches: Branches that rub together can damage bark and impair growth.
• Extended branches: Prune back overly long branches exceeding the natural shape and for clearance beneath the canopy.
• Dead limbs: Prune out dead and dying branches promptly.
• Damaged branches: Storm damage or other injury requires corrective pruning immediately.
• Congested interior: Dense inward-growing branches need thinning so as to improve airflow and light penetration.
• Diseased limbs: Prune cankers, verticillium wilt infections, and other diseases back to healthy wood.
• Weak branch unions: Narrow V-shaped branch forks are prone to breaking and need removal.

Trimming Redbud Trees Based on Size: The Process of Pruning Redbud Trees

Trimming Redbud tree is fairly straightforward. However, the trimming process differs slightly depending on the tree’s size and maturity.⁴

Here is how to trim your Redbud trees depending on size and maturity.

1. Gather Your Pruning Tools

Having sharp, clean gardening tools is critical to proper pruning. Here are the tools you will need for the pruning process.⁴

• Bypass pruners: Sharp bypass hand pruners make clean cuts on stems up to 1⁄2-inch in diameter.
• Loppers: Long-reach loppers can tackle branches up to 11⁄2 inches thick.
• Hand saw: A curved hand saw cuts through thicker branches that pruners can’t handle.
• Pole saw/pruner: Essential for pruning high branches that are out of reach. Choose one that is extendable up to 12 feet.
• Sterilizing spray: For sanitizing tools to prevent disease spread when cutting different trees and branches
• Protective gear: Gloves, eyewear, long sleeves, and hard hat for safety
• Tarps/trash bags: For collecting and disposing of debris cleanly and safely after pruning

2. Trim Young/Small Redbud Trees

For redbuds under 10 feet tall, hand pruning is often adequate for structural corrections and maintaining form but you can still use tools as needed.

Here are the steps to follow.

1. Sterilize your pruning tools with a disinfectant spray before making cuts to prevent transmitting diseases between branches and trees.
2. Eliminate all dead, dying, broken, and diseased branches first. Make clean collar cuts just outside the swollen branch bark ridge.
3. Identify branches that rub together, grow downward, or appear imbalanced. Remove them back to a lateral shoot or bud facing the outside of the tree.
4. Maintain ideal pyramidal shape by cutting back upper branches and leader stems. Select outward-facing buds as cutting points.
5. Remove vigorous vertical water sprouts emerging from the trunk that can compete with the main leaders.
6. Eliminate inward-growing competing branches and retain one dominant central leader for a strong structure.
7. Monitor for regrowth and make additional corrective cuts as needed into early summer before new growth fully hardens off.
8. Dispose of all pruned branches promptly and avoid pileups of brush which can harbor pests and disease.

3. Trim Large Mature Redbud Trees

Although pruning large mature trees requires more skill and expertise, it is still possible to prune them by yourself.

Follow these steps:

1. Sterilize your pruning tools with a disinfectant spray before making cuts to prevent transmitting diseases between branches and trees.
2. Clean out deadwood by first removing all diseased, dead and dying branches. Cut back split, cracked, or broken branches damaged by weather.
3. Reduce overextended branches by heading back upper branches and waterspouts that are too long for the canopy. Choose the outward-facing buds as cut points.
   Prune back branches overhanging structures, impeding lines of sight, or interfering with pedestrian/vehicle access beneath the canopy.
4. Eliminate lower branches for clearance beneath the canopy. Remove a few largest branches every couple of years.
5. Thin congested areas by selectively removing inward-growing branches and dense foliage to improve light and air penetration
6. Restore structure by removing broken lead branches then train new leaders with ties and splints. Prune competing leaders to retain ideal form.
7. Eliminate weak, narrow-angled V-shaped branch forks that can easily break under pressure but retain branches with wide U-shaped angles.
8. Use moderate crown reduction pruning to stimulate fresh growth on aging, overgrown trees so as to restore a more youthful structure.
9. Dispose of all pruned branches promptly and avoid pileups of brush which can harbor pests and disease

4. Avoid Making Mistakes When Trimming Redbud Tree

The last step in trimming Redbud tree for healthy foliage is to make sure you avoid making common pruning mistakes.⁷ These include;

• Topping: Avoid removing the central leader except on severely damaged or diseased trees as this will destroy your tree’s natural form.
• Over-thinning: Excessive inner branch removal starves the tree of energy production capacity.
• Excessive heading cuts: Repeated heading triggers congestion over time. As such, make thinning cuts instead to open up the interior.
• Cutting into old wood: Don’t cut back mature branches beyond where foliage emerges since older wood won’t generate new growth.
• Flush cuts: Pruning too close parallel to the trunk will leave branch collars vulnerable to decay organisms.
• Over-pruning: Removing too much foliage stresses trees and can invite diseases. Stick to removing no more than 25% of the live branches per season.
• Failing to properly disinfect tools: Thoroughly clean your tools between making cuts on different trees and branches to avoid transmitting diseases through open wounds.

By avoiding these common pruning mistakes, you can have the assurance that pruning your Redbud trees will result in healthier and more vibrant foliage.

Proper Pruning Cuts To Use When Trimming Redbud Trees

Where and how you prune your Redbud trees is critical.⁸ For proper trimming you can make the following cuts on redbuds:

• Collar cuts: When removing entire branches, angle your cuts just outside the swollen branch collar without leaving a stub. Also, make sure to angle your cuts away from the remaining stem tissue.
• Heading cuts: Shorten over-extended branches back to a side bud or lateral shoot by cutting at a 45-degree angle just above an outward-facing bud so as to direct new growth.
• Thinning cuts: You can also remove entire branches back to their point of origin or attachment, such as a larger branch or trunk.
• For large branches, use the three-cut pruning method to prevent tearing of the bark and cambium.⁹

1. Make an undercut several inches from the trunk to prevent tearing when the branch falls.
2. Next, make a top cut above the undercut to remove most of the weight.
3. Finally, cut outside the branch collar to remove the stub.

As mentioned before, never make flush cuts that remove the branch collar. Instead, leave branch collars intact for proper healing.

How Do I Prune an Overgrown Eastern Redbud?

For overgrown Eastern Redbuds,² first remove all dead wood and branches crossing or growing toward the center. Then, make heading cuts on overly long branches and thin congested areas but limit pruning to 25% of foliage.

It may take several seasons to properly restore the shape of your tree.

Why Should You Trim Your Redbud Trees: Benefits of Pruning Eastern Redbud Trees

There are several beneficial reasons why you should prune your Redbud trees:⁴

• Promote healthy foliage growth: Removing crowded, crossing branches opens up the canopy to allow better air circulation and sunlight penetration. This reduces moisture and disease while stimulating vibrant leaf growth while you grow a tree.
• Promote flowering: Pruning stimulates bud growth which leads to prolific flowering. Removing old flower stems after blooming also directs energy into new growth.
• Eliminate diseased limbs: Pruning out dead or infected branches prevents further spread of fungal diseases like Verticillium wilt and Cytospora canker.^5,6 Sanitation cuts into healthy wood also stop diseases in their tracks.
• Enhance natural form: Selective trimming maintains the elegant vase shape and tiered branching structure inherent to redbuds. You can achieve this by heading back wayward branches and opening up the interior.
• Prevent branch breakage: Pruning removes weak, V-shaped branch forks unable to bear the weight of leaves, flowers, snow or ice. This prevents hazardous broken limbs that could damage property or injure people.
• Rejuvenate old trees: Moderate thinning cuts invigorate aged trees by stimulating fresh growth. Renewal pruning restores vigor and shape.

When To Trim Redbud Trees

Timing is key when pruning redbuds.⁴ You want to avoid interfering with flowering, leafing out, or winter dormancy.

Here are some things to remember when trimming Redbud tree.

• Early spring before bud break: Prune your Redbud trees as the buds begin to swell just before new growth emerges. During this time, cuts heal quickly as trees direct energy into shoot development.
  Remove dead wood, reshape wayward branches, and preventively thin congested areas.
• Mid to late spring after flowering: Once flowers fade, finish reshaping and structural corrective pruning before new growth fully expands. However, avoid pruning once new shoots elongate and leaflets unfurl.
• Early summer: Head back shoots and prune to shape once new growth has hardened off in early summer. However, you can remove water sprouts anytime they appear.
• Winter: Minor maintenance pruning is possible when trees are dormant.
  You can selectively prune out dead wood and tree stem as needed. However, avoid major reshaping that could stimulate growth susceptible to winter damage.

Avoid pruning redbuds mid to late summer when cuts could initiate new growth before properly hardening off.

When To Call in Tree Trimming Experts: Contracting an Arborist or Tree Trimming Service

Although you can feasibly prune your Redbud trees by yourself, it is important to know when to recruit the help of tree trimming professionals.¹⁰
