Tree Wrap Damage Prevention (5 Pro Tips for Healthy Bark Care)

1. Understanding the Importance of Bark and Common Threats

Before diving into prevention, it’s crucial to understand why bark is so vital and what threats it faces. Think of bark as the tree’s skin. It’s the protective outer layer that shields the inner tissues from the elements, pests, and diseases. The bark contains the phloem, which transports nutrients from the leaves to the rest of the tree. Damage to the bark can disrupt this flow, weakening the tree and making it susceptible to further problems.

Key Bark Functions:

• Protection: Shields against sunscald, frost cracks, insect infestations, and fungal diseases.
• Nutrient Transport: The phloem layer within the bark carries sugars produced during photosynthesis to the roots and other parts of the tree.
• Water Regulation: Helps prevent excessive water loss from the tree.
• Structural Support: Contributes to the overall strength and stability of the tree.

Common Threats to Bark:

• Sunscald: Occurs when rapid temperature fluctuations, especially in winter, cause the bark to crack, often on the south or southwest side of the tree.
• Frost Cracks: Similar to sunscald, but caused by freezing temperatures expanding water within the bark.
• Animal Damage: Deer, rabbits, voles, and other animals can gnaw on bark, especially during winter when other food sources are scarce.
• Insect Infestations: Certain insects, like bark beetles, bore into the bark and can kill trees.
• Fungal Diseases: Fungi can enter through wounds in the bark and cause decay.
• Mechanical Damage: Lawn mowers, weed whackers, and other equipment can accidentally injure the bark.
• Improper Pruning: Wounds from incorrect pruning techniques can create entry points for pests and diseases.
• Tree Wrap Issues: Improper application or maintenance of tree wraps can lead to issues like girdling or creating a habitat for pests.

I once had a client who lost several young apple trees due to vole damage. They had planted the trees without any protection, and the voles completely girdled the trunks during a harsh winter. The trees never recovered. This experience underscored the importance of proactive bark protection, especially for young trees.

2. Choosing the Right Tree Wrap: Materials and Considerations

The market offers a variety of tree wrap materials, each with its pros and cons. Selecting the right one depends on the type of tree, the climate, and the specific threats you’re trying to address.

Types of Tree Wrap Materials:

• Crepe Paper Wrap: Inexpensive and biodegradable, providing good protection against sunscald and frost cracks. However, it degrades quickly and needs to be replaced annually. I’ve found that crepe paper wrap works best for short-term protection in mild climates.
• Plastic Tree Guards: Durable and reusable, offering excellent protection against animal damage. They can also help prevent sunscald. However, they can trap moisture if not properly ventilated, potentially leading to fungal growth. I prefer using plastic tree guards for young trees in areas with high deer populations.
• Burlap Wrap: A natural, breathable material that provides good protection against sunscald and frost cracks. It’s also relatively inexpensive and biodegradable. However, it can be susceptible to rot if it stays wet for extended periods. Burlap is a good option for wrapping larger trees or shrubs.
• Hardware Cloth: A wire mesh that provides excellent protection against rodents. It’s durable and long-lasting, but can be more expensive than other options. I often use hardware cloth to protect the base of trees from voles and rabbits.
• Specialty Tree Wraps: Some wraps are designed for specific purposes, such as insect control or disease prevention. These wraps often contain insecticides or fungicides.

Factors to Consider When Choosing a Tree Wrap:

• Climate: In cold climates, choose a wrap that provides good insulation against frost and sunscald. In humid climates, select a breathable wrap to prevent moisture buildup.
• Pest Pressure: If you have a high population of deer, rabbits, or voles, choose a wrap that offers physical protection against these animals.
• Tree Age: Young trees are more vulnerable to damage than mature trees and may require more protection.
• Tree Species: Some tree species are more susceptible to certain types of damage than others. For example, thin-barked trees like fruit trees are more prone to sunscald.
• Budget: Tree wraps range in price from inexpensive crepe paper to more expensive plastic or metal guards. Choose a wrap that fits your budget.
• Ease of Installation: Some wraps are easier to install than others. Consider your own skill level and the amount of time you’re willing to spend on installation.
• Environmental Impact: Consider the environmental impact of the wrap material. Biodegradable options like crepe paper and burlap are more environmentally friendly than plastic.

My Preferred Choices:

For young fruit trees, I typically use a combination of plastic tree guards and hardware cloth. The plastic guards protect against deer and sunscald, while the hardware cloth protects the base of the trunk from rodents. For larger trees, I often use burlap wrap during the winter months to prevent sunscald and frost cracks.

3. Step-by-Step Guide to Proper Tree Wrapping Techniques

Proper installation is just as important as choosing the right tree wrap. A poorly installed wrap can do more harm than good, creating a breeding ground for pests or constricting the tree’s growth.

General Steps for Tree Wrapping:

1. Timing: The best time to wrap trees is in the late fall, before the first hard frost. This gives the wrap time to provide protection throughout the winter months.
2. Preparation: Before wrapping, remove any loose or damaged bark from the trunk. This will help prevent pests and diseases from getting trapped under the wrap.
3. Material Preparation: Cut the wrap material to the appropriate length. You’ll need enough material to cover the trunk from the ground up to the first major branches.
4. Wrapping: Start at the base of the tree and wrap the material upwards, overlapping each layer by about 50%. This will ensure that the trunk is fully protected.
5. Securing: Secure the wrap with twine, tape, or staples. Be careful not to wrap too tightly, as this can constrict the tree’s growth.
6. Inspection: Regularly inspect the wrap throughout the winter months to make sure it’s still in good condition. Replace any damaged or missing sections.

Specific Techniques for Different Materials:

• Crepe Paper Wrap: Wrap tightly and securely, overlapping each layer by at least 50%. Secure with twine or tape. Replace annually.
• Plastic Tree Guards: Install according to the manufacturer’s instructions. Make sure the guard is properly ventilated to prevent moisture buildup. Check regularly for pests and remove any debris that accumulates inside the guard.
• Burlap Wrap: Wrap loosely and secure with twine. Avoid wrapping too tightly, as this can restrict air circulation.
• Hardware Cloth: Form a cylinder around the base of the tree and bury the bottom edge a few inches into the ground to prevent rodents from burrowing underneath. Secure the top edge with wire or zip ties.

A Case Study in Wrapping Fruit Trees:

I recently helped a local orchard owner wrap their young apple trees for the winter. We used a combination of plastic tree guards and hardware cloth. We started by clearing any weeds or debris from around the base of each tree. Then, we installed the hardware cloth cylinders, making sure to bury the bottom edge securely. Next, we placed the plastic tree guards over the hardware cloth, ensuring they were properly ventilated. Finally, we secured the guards with zip ties. This combination of protection effectively shielded the young trees from both animal damage and sunscald.

My Personal Tip:

When wrapping trees, I always try to leave a small gap between the wrap and the trunk. This allows for air circulation and prevents moisture buildup, reducing the risk of fungal diseases.

4. Beyond Wrapping: Additional Bark Care Practices

While tree wrapping is an effective way to protect bark, it’s just one piece of the puzzle. Other bark care practices can further enhance the health and resilience of your trees.

Essential Bark Care Practices:

• Proper Watering: Adequate watering is crucial for tree health. During dry periods, water trees deeply and regularly.
• Fertilization: Fertilize trees in the spring with a balanced fertilizer. This will provide them with the nutrients they need to grow and thrive.
• Mulching: Apply a layer of mulch around the base of trees. Mulch helps retain moisture, suppress weeds, and regulate soil temperature. I recommend using organic mulch, such as wood chips or shredded bark. Avoid piling mulch directly against the trunk, as this can create a moist environment that promotes fungal growth.
• Pruning: Prune trees regularly to remove dead, damaged, or diseased branches. Proper pruning techniques can improve air circulation and reduce the risk of disease. When pruning, make clean cuts and avoid tearing the bark.
• Wound Treatment: If a tree sustains a wound, clean the wound with a sharp knife and apply a wound dressing. This will help prevent infection and promote healing. However, research on wound dressings is mixed, and some arborists recommend leaving wounds open to the air.
• Pest and Disease Control: Monitor trees regularly for signs of pests and diseases. Take prompt action to control any infestations or infections.
• Sun Protection for Exposed Trunks: For newly planted trees or trees with thin bark that are exposed to intense sunlight, consider using tree paint or whitewash to reflect sunlight and prevent sunscald.
• Avoid Mechanical Damage: Be careful when mowing or using other equipment around trees to avoid damaging the bark.
• Soil Health: Ensure the soil around your trees is healthy and well-drained. Conduct a soil test to determine if any amendments are needed.

A Story of Recovery:

I once worked with a client whose mature oak tree had suffered significant bark damage from a lawn mower. The wound was large and exposed, and the tree was showing signs of stress. We carefully cleaned the wound, removed any loose bark, and applied a wound dressing. We also improved the soil around the tree and provided regular watering. Over the next few years, the tree gradually healed, and the wound eventually closed over. This experience demonstrated the importance of prompt and proper wound care.

My Favorite Mulch:

I’m a big fan of using wood chips as mulch around trees. Wood chips are a natural, sustainable material that provides excellent benefits for tree health. They help retain moisture, suppress weeds, and slowly release nutrients into the soil. I typically use wood chips from locally sourced trees, such as oak or maple.

5. Troubleshooting Common Tree Wrap Problems and Long-Term Management

Even with the best preparation and care, problems can sometimes arise with tree wraps. It’s essential to be vigilant and address any issues promptly to prevent further damage.

Common Tree Wrap Problems:

• Girdling: If a tree wrap is too tight, it can constrict the trunk and restrict growth, eventually girdling the tree. This is a serious problem that can kill the tree. To prevent girdling, make sure the wrap is not too tight and that it allows for some expansion of the trunk. Regularly check the wrap to ensure it’s not becoming too tight as the tree grows.
• Moisture Buildup: If a tree wrap is not properly ventilated, moisture can build up underneath, creating a favorable environment for fungal growth. To prevent moisture buildup, choose a breathable wrap material and ensure that the wrap is properly ventilated.
• Pest Infestations: Tree wraps can sometimes provide a hiding place for pests, such as insects and rodents. Regularly inspect the wrap for signs of pests and take action to control any infestations.
• Wrap Degradation: Tree wraps can degrade over time due to exposure to the elements. Regularly inspect the wrap and replace it as needed.
• Incorrect Application: Improper wrapping techniques can also lead to problems. Make sure to follow the instructions carefully when installing the wrap.

Troubleshooting Tips:

• Girdling: If you notice that a tree wrap is too tight, carefully loosen or remove it. If the tree has already been girdled, you may need to consult with an arborist to determine the best course of action.
• Moisture Buildup: If you notice moisture buildup under the wrap, remove the wrap and allow the trunk to dry out. Then, re-wrap the tree with a more breathable material or adjust the wrapping technique to improve ventilation.
• Pest Infestations: If you find pests under the wrap, remove the wrap and treat the tree with an appropriate insecticide or rodenticide. Then, re-wrap the tree with a new wrap.
• Wrap Degradation: If the wrap is damaged or degraded, replace it with a new wrap.
• Incorrect Application: If you realize that you’ve installed the wrap incorrectly, remove it and re-install it using the correct technique.

Long-Term Management:

• Regular Inspections: Regularly inspect your trees and their wraps for any signs of problems. This will allow you to catch issues early and take prompt action.
• Wrap Removal: Remove tree wraps in the spring, after the risk of frost and sunscald has passed. This will allow the tree to breathe and grow freely.
• Ongoing Care: Continue to provide your trees with proper watering, fertilization, mulching, and pruning. This will help them stay healthy and resilient.
• Professional Consultation: If you’re unsure about any aspect of tree care, consult with a certified arborist. An arborist can provide expert advice and assistance.
