Pests and diseases are widely known to affect the health of trees, but they’re not the only threat. Abiotic tree disorders are on the rise—especially in urban areas like Denver. Caused by non-living factors like drought, temperature, wind, and nutrient deficiencies, abiotic disorders can quickly injure otherwise healthy plants. Understanding and preventing these issues before they become a problem can keep your trees in good condition year-round.
Common Abiotic Tree Disorders in Denver
There are many abiotic tree disorders that can affect trees, but the most common types can vary based on your region and climate. Denver trees are susceptible to drought stress, soil issues, planting mistakes, and salt damage.
Drought Stress
Denver’s dry, arid climate lends itself to drought-like conditions, and improper watering practices just make the symptoms worse. Look for the following signs that your trees are suffering from drought stress:
- • Wilting leaves
- • Leaf scorch
- • Stunted growth
Soil Issues
Compacted soil in urban areas makes it difficult for roots to growl and restricts areas for water to penetrate the soil. Poor drainage also contributes to the problem, leading to root rot and weakened trees. Because the soil conditions are not optimal for plants to grow, trees can suffer from nutrient deficiencies. When they aren’t getting the nutrients they need to grow and produce leaves, their growth can be severely stunted.
Compacted soil – restricts root growth and water infiltration.
Planting Mistakes
Young trees are vulnerable to a whole host of problems that can begin with improper planting. Often, homeowners plant trees too deep, which smothers the roots and hinders growth. The root flare, located at the base of the tree, is also incredibly delicate and essential to your tree’s overall health. When these roots are damaged, the tree is weakened and becomes susceptible to a whole host of diseases.
Many homeowners also set themselves up to battle abiotic tree disorders by purchasing the wrong trees. It’s incredibly important to pick native trees that can grow and thrive in your climate and conditions.
Salt Damage
Winter runoff from snow and de-icing techniques can let salt and other debris leech into your soil. Symptoms of salt damage look like:
- • Leaf scorch
- • Stunted growth
- • Overall declining tree health
Preventing Abiotic Tree Disorders
Luckily, there are several ways you can prevent abiotic tree disorders from affecting the trees in your yard.
Proper Planting Techniques
Do your research about proper planting techniques and select trees that will thrive on your property. Consider the mature size of your tree, its sunlight needs, and the soil conditions that are required for healthy growth. Then, research the correct planting depth so that the root ball is planted properly. Make sure you know how to handle the root ball so the root flare isn’t damaged throughout the planting process.
Watering Practices
Denver’s arid climate means you’ll probably have to water your plants regularly. Use the deep watering method to encourage deep root growth and drought tolerance. Water your plants as needed to avoid overwatering them, which can be just as problematic as underwatering them.
Experts also recommend mulching around the base of each tree. This allows moisture to permeate the roots underneath, and it keeps the soil at a safe temperature for growth.
Soil Management
It’s hard to tell whether your soil needs to be amended for proper tree growth. Test the pH and nutrient levels so you can determine what needs to be added for optimal growing conditions. If your soil is compacted, aerate the area to improve drainage and allow oxygen to get to your tree’s roots.
Winter Protection
Although it isn’t always necessary, many young and sensitive trees can benefit from winter protection. Consider wrapping the trunks of these trees and take additional measures to protect the roots from salt exposure.
Control of Existing Abiotic Disorders
If your trees are already suffering from abiotic disorders, it’s best to act quickly. Observe the tree’s symptoms and determine which disorder it’s suffering from (and to what severity). Your solutions may include:
- • Adjusting your watering practices
- • Amending your soil conditions by adding nutrients
- • Pruning dead or damaged branches
Severe cases should be checked out by a professional arborist. They have the skillset to quickly diagnose the problem so you can act quickly to save your tree.
