Young fruit trees are especially vulnerable to environmental stressors, with sun scald and wind damage being two of the most common threats. These challenges can stunt the growth of young trees, damage their bark, and even threaten their survival. Fortunately, with some proactive measures, you can protect your young fruit trees and help them establish strong, healthy growth. In this blog post, we’ll explore what sun scald and wind damage are, how they affect young trees, and the best ways to safeguard them.

What Is Sun Scald?

Sun scald is a damage to a tree’s bark caused by excessive exposure to the sun, often in the winter months or early spring. It typically occurs when there is a sharp contrast between daytime warmth and nighttime freezing temperatures. The sun heats up the tree’s trunk during the day, causing it to lose moisture. When the temperature drops suddenly at night, the bark can crack, and the tissues beneath the bark may be damaged.

Sun scald is particularly damaging to young trees because their bark is thinner and less resilient than that of mature trees. If left unprotected, it can expose the tree to further damage, such as infection or pest infestation, and slow down the tree’s growth.

What Is Wind Damage?

Wind damage occurs when young fruit trees are exposed to high winds, which can cause their branches and trunks to bend or break. It can also damage the tree’s root system if the soil is too loose. For young trees, wind damage is particularly dangerous because they have not yet developed the strong root systems or rigid structure to withstand strong gusts.

Wind stress can lead to:

  • Broken branches or bent trunks.

  • Root damage due to soil erosion or instability.

  • Loss of moisture from desiccation (drying out) if wind is constant and drying.

How to Protect Your Young Fruit Trees from Sun Scald

1. Wrap the Trunk

Wrapping the trunk with materials like tree wrap, burlap, or specialized tree guards is one of the most effective ways to protect against sun scald. The wrap helps to shield the bark from intense sun exposure and helps regulate temperature fluctuations.

How to wrap your tree:

  • Start the wrap at the base of the trunk, covering the entire exposed section.

  • Avoid wrapping too tightly—ensure the material allows air circulation.

  • For trees with thin bark, it’s especially important to begin wrapping in late fall and remove it in early spring to prevent the tree from overheating.

2. Paint the Trunk

Another effective method is to paint the trunk with diluted white latex paint. This reflects sunlight and helps prevent the bark from heating up during the day, reducing the risk of sun scald. The paint acts like sunscreen, offering a protective layer that blocks UV rays.

How to apply paint:

  • Mix one part white latex paint with two parts water.

  • Apply the mixture directly to the trunk, making sure to cover the exposed areas.

  • Reapply as necessary, especially after rain.

3. Provide Shade

If your young fruit trees are located in an area with intense midday sun, providing shade can help. Use shade cloth, burlap screens, or even temporary structures like trellises or garden fencing to shield the tree from harsh sunlight, especially during the hottest part of the day.

How to Protect Your Young Fruit Trees from Wind Damage

1. Staking the Tree

Staking is one of the most effective ways to protect young fruit trees from being blown over or damaged by wind. When staking, ensure that the tree is secure but able to sway gently. Too rigid a stake can prevent the tree from developing strong trunk tissue, which is essential for long-term stability.

How to stake your tree:

  • Use soft ties (such as rubber tree ties or cloth strips) to attach the tree to a stake.

  • The stake should be positioned in the ground next to the tree, about 6-12 inches away.

  • Ensure the tree can still sway slightly, as this movement encourages strength and trunk development.

2. Windbreaks and Barriers

Creating a windbreak or installing wind barriers around your young trees helps reduce the force of wind. You can use materials like fence panels, bamboo screens, or natural windbreaks such as hedges or shrubs.

How to set up a windbreak:

  • Place the windbreak upwind of your trees, ensuring it’s high enough to block the majority of the wind.

  • If using shrubs or trees as natural windbreaks, make sure they are planted far enough away so they don't compete with your fruit trees for nutrients and water.

3. Proper Planting

Planting your young fruit tree in a location that naturally shields it from strong winds can help reduce damage. Avoid planting young trees in exposed, open fields or in low-lying areas that may be prone to wind gusts. Consider areas with natural topography, like hillsides or areas near buildings that offer some protection.

Additional Tips for Protecting Young Fruit Trees

1. Mulching Around the Base

Mulch not only helps retain moisture and regulate soil temperature, but it can also provide some wind protection. A thick mulch layer (about 3-4 inches) helps protect young trees by reducing soil erosion caused by wind and keeping the root zone stable. Just make sure not to pile mulch against the trunk.

2. Regular Inspection and Maintenance

Frequent inspection of your young trees ensures that early signs of damage are noticed and addressed promptly. Keep an eye out for signs of bark cracking, branch bending, or broken trunks, and take action right away.

Final Thoughts

Young fruit trees are incredibly vulnerable to environmental stressors like sun scald and wind damage, but with proper care, they can grow strong and resilient. By wrapping trunks, staking trees, installing windbreaks, and providing proper shade, you can help protect your trees and give them the best chance for long-term success.
