Summer in Utah brings beautiful long days, but it also brings intense heat and a blazing sun that can take a heavy toll on your yard. If you have recently added new trees to your property, you might notice they are struggling to stay green and healthy.
Young trees have thin, sensitive bark that easily gets damaged by our desert climate. When the sun beats down on these fragile trunks, it can cause a serious condition known as sunscald, which can permanently weaken or even kill a young tree. Taking a few simple steps right now can keep your investment safe and ensure your landscape thrives for years to come.

What Is Sunscald and Why Does It Happen
Sunscald is essentially a severe sunburn on a tree trunk. In Utah, the summer sun gets incredibly hot, and the light reflects off dry soil, rocks, and nearby sidewalks. This extra heat cooks the live tissues just beneath the bark, causing the cells to die.
When a tree is young, its bark is thin and smooth, offering very little natural protection against intense ultraviolet rays. Older trees have thick, corky bark that acts like a shield, but young trees are left entirely vulnerable to the elements.
As summer progresses, the damaged bark will begin to dry, crack, and eventually peel away from the trunk. This open wound exposes the inner wood to insects and diseases that can cause deeper structural harm.
Understanding the signs of sunscald can help you catch the problem before it causes long-term damage to your yard. Look out for these common warning signs on the south or southwest side of your tree trunks:
- Discolored patches of bark that look unusually dark, red, or unnaturally pale
- Sunken areas along the trunk that feel soft or brittle to the touch
- Long vertical cracks opening up in the bark during the hottest weeks of July and August
- Large pieces of bark peeling completely away from the wood underneath
Shielding Young Bark with Protective Wraps
One of the most effective ways to protect a fragile trunk from the blazing desert sun is to use a physical barrier. Tree wraps act like a long-sleeved shirt, reflecting intense sunlight and keeping the bark much cooler.
You can find inexpensive, breathable paper tree wraps at almost any local garden center. These wraps are easy to apply and provide immediate relief to your trees during the hottest months of the year.
When applying a wrap, always start at the very base of the tree near the soil line and work your way upward. Overlap each turn by about an inch to ensure there are no gaps where the sun can peek through. Stop wrapping just below the first main set of branches so the tree can still move naturally in the wind.
Keep these vital wrapping tips in mind to ensure your tree stays healthy underneath the protective layer:
- Wrap the trunk snugly but not too tightly, as a tight wrap can strangle the tree and restrict nutrient flow.
- Use flexible paper wrap or white plastic guards rather than dark materials, which actually absorb heat and make the problem worse.
- Check underneath the wrap once a month to make sure no pests have hidden inside, and that moisture is not trapped against the bark.
- Remove the wrap in late autumn or early spring so the trunk can get fresh air and harden off naturally.
Using Deep Mulch to Cool the Soil
While protecting the trunk is critical, you also need to care for the root system hiding just beneath the surface. High soil temperatures can scorch tender young roots, making it impossible for the tree to drink enough water to stay cool.
Applying a thick layer of organic mulch around the base of your tree acts like an insulating blanket for the soil. Mulch keeps the root zone significantly cooler and prevents moisture from evaporating into the dry Utah air.
For the best results, use shredded bark or wood chips and spread them in a wide circle around the tree. This circle should ideally extend out as far as the lowest branches reach, which is known as the drip line.
To give your new additions the best head start, professional tree planting techniques always emphasize proper mulching. Avoid piling the mulch directly against the bark in a cone shape, as this traps moisture and creates a perfect home for rot and harmful insects. Instead, leave a space of three to four inches completely clear of mulch around the base of the trunk.
Smart Watering Habits for Hot Weather
Watering a young tree in the desert requires a completely different approach than watering a standard lawn. Grass roots sit in the top few inches of soil, but tree roots need to grow deep into the earth to find stability and lasting moisture.
Sprinklers that run for a few minutes every day only wet the surface, leaving the deep roots completely dry and stressed. This constant stress makes the tree much more susceptible to sunscald and heat exhaustion.
The secret to summer survival is deep, infrequent watering that encourages roots to grow downward. Run a slow-trickle hose or a drip irrigation system at the base of the tree for an hour or two at a time. This slow delivery allows the water to soak deep into the dirt, where the roots can slowly drink it in over several days.
Establishing a consistent summer watering routine will keep your landscape vibrant even during a heatwave:
- Water young trees thoroughly 2 to 3 times a week during the hottest parts of summer.
- Check soil moisture by pushing a long screwdriver or your finger 6 inches into the ground near the tree.
- Apply water early in the morning or late in the evening to minimize evaporation from the sun and wind.
Long Term Care and When to Call an Expert
Caring for young trees is rewarding, but it requires patience and consistent effort throughout the changing seasons. As your trees grow and adapt to the Utah climate, their care needs will change.
Consistently monitoring your landscape helps you catch minor issues before they become costly problems. Investing time in routine tree maintenance now will pay off with beautiful, mature shade trees in the future.
Sometimes, despite your best efforts, a tree might show signs of severe distress, such as dropping all its leaves or developing deep trunk wounds. In these moments, having an experienced eye look over your yard can provide peace of mind.
A professional team can accurately assess structural damage, identify hidden pests, and recommend specialized treatments to help a struggling tree recover. Seeking assistance early can save you the heartache and expense of replacing a beloved landscape feature.
