5 Tree Care Mistakes to Avoid in Phoenix

Trees provide so many benefits to our environment. They purify the air we breathe by absorbing harmful pollutants, shade our homes and streets from the sun, and provide habitats for countless species of birds, insects, and other wildlife, just to name a few.

But here in the Sonoran Desert, our trees are different, and they have a unique set of challenges in order to survive. The relentless sun beats down mercilessly, sapping moisture from the air and soil. Rain, when it does come, is often scarce and unpredictable, leaving trees to fight for every drop.

To help our trees thrive, despite these challenges, we must avoid the following desert tree care mistakes:

Mistake #1: Planting the Wrong Tree in the Wrong Place

One of the most common mistakes people make is selecting a tree that simply isn’t suited for the harsh realities of the desert environment. Water needs and sun tolerance vary greatly between different tree species. A thirsty maple, that’s accustomed to ample rainfall, will be miserable (and doomed) in our arid climate.

Another factor to consider is where you plant your tree. When it comes to planting the right tree in the right place, consider the following:

  • Matching Water Needs and Availability: Select trees with water requirements that align with your watering capabilities or access to water sources (like greywater systems). Remember, drought-tolerant trees are ideal for our arid climate.
  • Sun Exposure: Think about how much sun the planting location receives throughout the day. Some trees thrive in full sun, while others prefer dappled shade or afternoon relief from the intense sun. If your tree prefers partial shade, consider planting it on the north side of your home.

Mistake #2: Overwatering or Underwatering

With rain being a rare visitor in and around Phoenix, thirsty trees become stressed and struggle to survive. Most homeowners think that throwing a garden hose at the base of the tree for a few minutes will help keep the tree alive. But it actually does just the opposite.

Roots naturally grow towards water sources, and if the only readily available water source is near the soil surface due to frequent shallow watering, the roots will concentrate there. This shallow root system leaves the tree vulnerable to drying out during our hot spells.

Desert soil also contains salt. Frequent shallow watering doesn’t allow these salts to leach down through the soil, past the root zone. So, as your trees’ roots are desperately reaching for the shallow moisture, the buildup of salts hinders their ability to absorb water and nutrients, leaving them even more stressed and vulnerable in the harsh desert environment.

However, overwatering can be just as detrimental. Frequent oversaturation of the soil restricts oxygen to the roots. The best way to provide supplemental water to your trees is through deep watering, which involves less frequent but longer watering sessions that target the drip line—the outer edge of the tree’s canopy where most roots are located.

Mistake #3: Failing to Mulch or Using Insufficient Mulch

Many residents underestimate the power of mulch for their desert trees. Did you know applying mulch around the base of your trees can help significantly reduce the rate at which moisture escapes from the soil, keep the soil cooler to promote root growth, and even suppress weeds?

While xeriscape or hardscape materials might seem like a convenient alternative to help limit the need for frequent watering, they can actually harm your trees by absorbing heat and adding unnecessary weight to the root system.

To maximize the benefits of mulch, spread a 2–3-inch layer around the base of your tree, creating a donut shape that reaches the drip line. Avoid piling mulch directly against the trunk, as this can lead to moisture issues and rot. By using organic mulch strategically, you can give your desert trees a significant advantage in the harsh Phoenix climate.

Mistake #4: Neglecting Pruning or Improper Pruning

Neglecting or improperly pruning your trees can have serious consequences. Weak, overgrown branches are more likely to break in strong desert winds, leaving your trees vulnerable and potentially causing damage to your property. Overcrowded canopies can also hinder air circulation, creating a breeding ground for disease.

But it’s not just about preventing problems – proper pruning also enhances the beauty of your trees. Imagine unsightly, jagged cuts left behind by improper techniques. These not only detract from your landscaping but can also leave your tree open to infection. A Certified Arborist has the knowledge and experience to make the right cuts, striking a balance between removing problem branches and preserving your tree’s overall health and aesthetics.

However, avoid pruning during the hottest parts of the year, as fresh cuts and exposed interior leaves are susceptible to sunburn, adding stress to already heat-stressed trees. Instead, schedule pruning during the milder temperatures of late fall or winter.

Mistake #5: Ignoring Signs of Distress

Desert tree stress is a silent struggle. Unlike us, trees can’t verbally express their discomfort. So, you must observe your trees frequently and get really good at detecting subtle clues that might indicate trouble is brewing. The most common signs of tree stress in the desert are:

  • Wilting or drooping leaves
  • Leaf discoloration
  • Premature leaf drop
  • Stunted growth
  • Cracked or missing bark
  • Oozing sap

If you suspect your tree is experiencing any of these signs, don’t wait! Early intervention can help prevent further damage from occurring.
