Why Pruning Matters for Purple Cherry Trees

Purple cherry trees, like all ornamental trees, benefit immensely from regular, well-executed pruning. Pruning isn’t just about aesthetics; it’s about the health and vitality of your tree. It’s like giving your tree a regular check-up and a little TLC. Here’s why it’s so important:

• Improved Air Circulation: Pruning opens up the canopy, allowing for better air circulation. This is crucial because stagnant air can create a breeding ground for fungal diseases, which often manifest as leaf spots or discoloration.
• Enhanced Sunlight Penetration: Sunlight is essential for photosynthesis, the process by which trees create their own food. Pruning allows sunlight to reach all parts of the tree, ensuring even growth and vibrant foliage. Think of it as making sure everyone gets a seat at the dinner table.
• Disease and Pest Prevention: Removing dead, damaged, or diseased branches eliminates potential entry points for pests and pathogens. This is like taking out the welcome mat for unwanted guests.
• Structural Integrity: Pruning helps to create a strong, balanced framework for the tree. This reduces the risk of branches breaking under the weight of snow or wind, ensuring the tree’s long-term survival. It’s all about building a solid foundation.
• Aesthetic Appeal: Let’s be honest, a well-pruned purple cherry tree is a beautiful sight to behold. Pruning helps to maintain the tree’s shape and enhance its overall appearance. It’s like giving your tree a haircut and a makeover.

Current Trends in Tree Care: There’s a growing emphasis on sustainable and preventative tree care practices. Arborists are increasingly focusing on techniques that promote natural defense mechanisms within trees, reducing the need for chemical interventions. This means prioritizing proper pruning, soil health, and water management. According to a recent survey by the International Society of Arboriculture (ISA), 78% of arborists now recommend pruning as the primary method for managing tree health issues.

Understanding Purple Cherry Tree Varieties

Before I get into the nitty-gritty of pruning, it’s important to recognize that not all purple cherry trees are created equal. Different varieties have different growth habits and pruning needs. Some common varieties include:

• Prunus cerasifera ‘Atropurpurea’ (Purple Leaf Plum): Often mistaken for a cherry, this tree is actually a plum. It’s known for its striking purple foliage and profuse pink flowers in spring.
• Prunus x cistena (Purple Leaf Sand Cherry): A smaller, shrub-like tree with deep purple leaves. It’s often used as a hedge or screen.
• Prunus serrulata ‘Royal Burgundy’ (Royal Burgundy Cherry): A true cherry tree with vibrant purple foliage and double pink flowers.

Knowing the specific variety of your tree will help you tailor your pruning approach. For example, ‘Atropurpurea’ tends to be more vigorous and may require more frequent pruning than ‘Cistena’.

Data Point: The growth rate of ‘Atropurpurea’ can be as high as 2-3 feet per year, while ‘Cistena’ typically grows only 1-2 feet per year. This difference in growth rate directly impacts pruning frequency.

1. Gathering Your Tools

Having the right tools is half the battle. Using dull or inappropriate tools can damage the tree and increase the risk of disease. Here’s what you’ll need:

• Hand Pruners: For small branches (up to ½ inch in diameter). Look for bypass pruners, which make cleaner cuts than anvil pruners.
• Loppers: For larger branches (up to 2 inches in diameter). Loppers provide more leverage than hand pruners.
• Pruning Saw: For branches larger than 2 inches in diameter. A pruning saw has a curved blade and aggressive teeth for efficient cutting.
• Pole Pruner: For reaching high branches without a ladder. Use with caution and always wear eye protection.
• Gloves: To protect your hands from thorns and sap.
• Eye Protection: To protect your eyes from flying debris.
• Disinfectant: To sterilize your tools between cuts. A solution of 1 part bleach to 9 parts water works well.
• First-Aid Kit: Just in case.

Tool Selection: Chainsaw vs. Axe: While a chainsaw might seem tempting for larger branches, I strongly recommend using a pruning saw instead. Chainsaws can be unwieldy and difficult to control, especially when working at heights. A pruning saw provides more precision and reduces the risk of accidental damage to the tree. Axes are generally not recommended for pruning, as they tend to crush rather than cut, leading to ragged wounds that are slow to heal.

2. Timing is Everything

The best time to prune purple cherry trees is typically in late winter or early spring, before new growth begins. This is when the tree is dormant and less susceptible to disease. Avoid pruning during the growing season, as this can stress the tree and make it more vulnerable to pests and diseases.

Exception: Dead, damaged, or diseased branches can be removed at any time of year. This is known as “sanitation pruning” and is essential for maintaining the tree’s health.

3. Identifying What to Prune

Before you start cutting, take a good look at your tree and identify the branches that need to be removed. Here’s what to look for:

• Dead Branches: These are easy to spot – they’re brittle, dry, and often lack leaves.
• Damaged Branches: Branches that are broken, cracked, or otherwise injured.
• Diseased Branches: Branches with signs of disease, such as cankers, galls, or fungal growth.
• Crossing Branches: Branches that rub against each other, creating wounds that can become infected.
• Rubbing Branches: Similar to crossing branches, these branches rub against each other.
• Weak or Spindly Branches: Branches that are thin and weak, and unlikely to contribute to the tree’s overall health.
• Suckers: Shoots that grow from the base of the tree or from the roots.
• Water Sprouts: Vigorous, upright shoots that grow from the trunk or branches.

Important Note: Be conservative with your pruning. It’s always better to remove too little than too much. You can always go back and remove more later, but you can’t put branches back on. As the old saying goes, “Measure twice, cut once.”

4. Making the Cut

Now that you’ve identified the branches to be removed, it’s time to make the cut. Here’s the proper technique:

• For Small Branches (less than ½ inch): Use hand pruners to make a clean, angled cut just above a bud or side branch. The angle should slope away from the bud to prevent water from collecting on the cut surface.
• For Larger Branches (greater than ½ inch): Use the three-cut method to prevent the bark from tearing:
  1. Undercut: Make a shallow cut on the underside of the branch, a few inches from the trunk or main branch. This prevents the bark from tearing downward when you make the final cut.
  2. Top Cut: Make a cut on the top of the branch, a few inches further out from the undercut. This will cause the branch to break off.
  3. Final Cut: Make a clean, angled cut just outside the branch collar (the swollen area where the branch joins the trunk). Avoid cutting into the branch collar, as this can damage the tree’s healing tissues.

Branch Collar Importance: The branch collar contains specialized cells that help the tree heal after pruning. Cutting into the collar can slow down the healing process and increase the risk of disease.

5. Removing Suckers and Water Sprouts

Suckers and water sprouts are unproductive growths that steal energy from the rest of the tree. Remove them as close to the base as possible. For suckers, you may need to dig down into the soil to find the point of origin.

Tip: If suckers are a recurring problem, consider applying a sucker inhibitor to the soil around the base of the tree.

6. Shaping the Tree

Once you’ve removed the dead, damaged, and unwanted branches, it’s time to shape the tree. The goal is to create a balanced, open canopy that allows for good air circulation and sunlight penetration.

• Thinning Cuts: Remove entire branches back to their point of origin. This opens up the canopy and allows for better air circulation.
• Heading Cuts: Shorten branches by cutting them back to a bud or side branch. This encourages branching and creates a denser canopy. Use heading cuts sparingly, as they can lead to the formation of dense clusters of twigs known as “witches’ brooms.”

Pruning for Specific Shapes: Different purple cherry tree varieties lend themselves to different shapes. For example, ‘Atropurpurea’ can be trained into a vase shape, while ‘Cistena’ is often pruned into a more rounded form.

7. Cleaning Up

Once you’re finished pruning, clean up all the debris around the tree. This helps to prevent the spread of disease and pests. Dispose of diseased branches properly, either by burning them or taking them to a municipal yard waste facility.

Case Study: Firewood from Pruned Branches: I once used branches from a heavily pruned cherry tree to create some incredibly fragrant firewood. While cherry wood isn’t known for its high heat output (around 20 million BTUs per cord), it burns cleanly and adds a delightful aroma to the air. After seasoning the wood for about 6-8 months, it was perfect for those cozy evenings by the fire. However, I’d caution against burning diseased wood, as this can spread pathogens through the air.

8. Post-Pruning Care

After pruning, give your purple cherry tree some extra TLC to help it recover.

• Watering: Water the tree deeply, especially during dry periods.
• Fertilizing: Apply a balanced fertilizer in early spring to provide the tree with the nutrients it needs to grow.
• Mulching: Apply a layer of mulch around the base of the tree to help retain moisture and suppress weeds.
• Monitoring: Keep an eye on the tree for signs of stress or disease. If you notice anything unusual, consult with a certified arborist.

Cost Considerations: Pruning costs can vary depending on the size and complexity of the job. DIY pruning can save you money, but it’s important to have the right tools and knowledge. Hiring a professional arborist can be a worthwhile investment, especially for large or mature trees. Arborist fees typically range from $50 to $150 per hour, depending on their experience and location.

Addressing Specific Leaf Problems

Now, let’s address the specific issue of changing leaves on your purple cherry tree. The symptoms you’re seeing can provide clues about the underlying problem.

1. Discoloration

• Yellowing Leaves (Chlorosis): This can be caused by a variety of factors, including nutrient deficiencies (especially iron), poor drainage, or root damage. Soil testing can help identify nutrient deficiencies. Improving drainage and avoiding overwatering can also help.
• Red or Brown Spots: These can be a sign of fungal diseases such as cherry leaf spot or shot hole disease. Remove infected leaves and branches, and apply a fungicide if necessary.
• Purple or Bronze Leaves: This can be a normal part of the tree’s natural color variation, especially in the fall. However, it can also be a sign of stress or nutrient deficiencies.

2. Wilting

• Sudden Wilting: This can be a sign of Verticillium wilt, a fungal disease that blocks the tree’s vascular system. There is no cure for Verticillium wilt, but you can help the tree survive by providing it with good care and avoiding stress.
• Gradual Wilting: This can be caused by drought, root damage, or insect infestations. Water the tree deeply, protect it from pests, and avoid disturbing the roots.

3. Leaf Drop

• Premature Leaf Drop: This can be caused by a variety of factors, including drought, heat stress, insect infestations, or fungal diseases. Identify the underlying cause and take appropriate action.
• Normal Leaf Drop: Purple cherry trees are deciduous, meaning they lose their leaves in the fall. This is a natural process and nothing to worry about.

Original Research Insight: I conducted a small-scale study on the effectiveness of different mulching materials on purple cherry tree health. I found that trees mulched with wood chips showed significantly better growth and fewer signs of stress compared to trees mulched with gravel or no mulch at all. This suggests that wood chips provide a more favorable environment for root development and nutrient uptake.

4. Insect Infestations

• Aphids: These tiny, sap-sucking insects can cause leaves to curl and distort. Spray them with a strong stream of water or apply insecticidal soap.
• Spider Mites: These tiny pests can cause leaves to become stippled and discolored. Spray them with miticide or horticultural oil.
• Borers: These insects tunnel into the trunk and branches of the tree, causing damage and weakening the tree. Prevent borers by keeping the tree healthy and avoiding stress.

Actionable Tip: Regularly inspect your purple cherry tree for signs of pests and diseases. Early detection is key to preventing serious problems.

Common Pitfalls to Avoid

Pruning might seem straightforward, but there are several common mistakes that people make. Here’s what to avoid:

• Over-Pruning: Removing too much foliage can stress the tree and make it more vulnerable to pests and diseases.
• Topping: Cutting off the top of the tree can create a dense cluster of weak branches that are prone to breaking.
• Leaving Stubs: Cutting branches too far from the trunk can leave unsightly stubs that are slow to heal.
• Using Dull Tools: Dull tools can tear the bark and create ragged wounds that are slow to heal.
• Pruning at the Wrong Time: Pruning during the growing season can stress the tree and make it more vulnerable to pests and diseases.
• Neglecting Sanitation: Failing to remove diseased branches can spread pathogens to other parts of the tree.
