We rely on trees to give for shade and cooling, but are we doing enough to help our trees survive the low desert heat? Let’s take a look at some signs of heat stress and how to protect trees during peak summer heat. How Heat Affects Trees Trees move water through their roots, trunks, branches and leaves, then into the air through a process called transpiration; it’s similar to sweating in people. This is a natural process that keeps a tree healthy and growing. Heat increases how much water the tree loses during transpiration. When a tree suffers stress from heat and loss of water, it is more vulnerable to disease or pest damage. Wounds on a tree trunk or branch are less able to heal because the tree is using all its energy just to stay alive in hot, dry weather. Signs of Heat Stress It can be difficult...

We don’t have to tell you it’s hot in the summer around Phoenix. Plants often need more water during peak heat, and trees are no exception. But it’s not just about air temperature when it comes to tree health – our unique Valley climate affects when and how much water trees need. So here are a few summer watering tips for Phoenix-area homeowners. August is Hotter, but Trees Often Need More Water in June In Phoenix, summers heat up toward the middle of the summer season, but the air also is more humid in July and August (especially after a good monsoon rain). Humidity might make you feel hotter but it can also slow a tree’s evapotranspiration. That’s the name for the loss of water through evaporation (from the soil) and transpiration, the process that carries water from a tree’s roots to its branches, leaves, and finally into the air...

The annual Phoenix monsoons can be exciting – and dangerous. Extending from mid-June through the end of September, monsoon season brings with it torrential rain, dust storms, violent thunderstorms, and high winds that put trees and property at risk. Monsoon damage to trees is usually caused by strong winds, especially if there’s been recent heavy rain. When our clay soils get saturated with rainwater, tree roots are less able to hold a tree firmly in place. This is particularly true for recently-planted trees that haven’t yet developed a large root system. The end result is trees being toppled by monsoon winds as the roots are pulled out of the ground. Storms also cause broken branches and even snapped tree trunks. While you can’t completely eliminate the possibility of storm damage during monsoon season, there are things you can do to protect yourself and minimize the risk. Much of the damage...

Shade is a top benefit of trees, but trees also can block wind or noise, offer privacy for homeowners and provide shelter and food for birds and other wildlife. Evergreen trees give you those benefits year-round. We usually picture evergreen trees on ski slopes and other cool locations. But the five evergreens listed below can handle desert heat and use little water. Think about adding one of these evergreen trees to your Anthem area landscape. Acacia - Especially Mulga ( Acacia aneura ) The Mulga is a thornless tree native to Australia that can bloom with puffy yellow flowers several times a year, usually in spring and summer. Its thin leaves are silver gray. The tree grows slowly to a mature height of at least 20 feet. The Mulga needs full sun, loves the heat of zones 8 through 11, and is a great evergreen choice for Phoenix-area xeric gardens....

Growing trees in the low desert can offer many benefits to the homeowners who plant them, as well as to their neighborhoods. Consider these six reasons to plant trees in your Phoenix yard: #1 - Shade for Your Home (And Community) Placing trees in your yard and around your home can shade outdoor living areas and even help cool your home – and lower your energy bill as a result. Planting a tree on the west side of your Phoenix home, for example, can shade your patio or living areas and reduce air conditioning demand. If you plant a deciduous tree (one that loses leaves in winter), the sun can help warm your patio or living space in winter. Of course, the benefits of shade from trees is obvious to anyone who spends time outdoors. The shade is a great place for kids to play and adults to cool off...

Spring is a wonderful time to be outdoors in the Anthem area, especially if you love the sight and scent of early blooms on spring-flowering trees. Here are the best spring bloomers for our area: Desert Willow The Desert Willow ( Chilopsis linearis ) is a favorite of Phoenix-area homeowners because of its gorgeous spring blooms and tendency to grow fast. The flowers, in varying shades and depths of pink, are fragrant and their trumpet shape attracts hummingbirds. The Desert Willow has plenty of other good qualities. It thrives in sun, is native to the Southwest and needs little water. If you prefer a single trunk and tree-like canopy, Desert Willow can be pruned to that shape, or pruned to have multiple trunks and more of a large shrub appearance. This is an easy tree to care for, and one of the only concerns is to avoid giving the tree...

Agaves are striking accent plants in Phoenix-area gardens and a favorite in our hot, dry landscapes. A frequently-seen agave is the century plant ( Agave americana ). It's a large and gorgeous agave with sharp spines along its blue-green leaves and puts up a towering bloom stalk before the plant dies. Healthy agaves can grow for 25 years or more. When mature, agaves need to be planted in soil that drains well and gets plenty of sun; young plants need a little shade. Other than that, the plants need little care and have few pests or problems. However, there is one pest that can destroy agaves. The agave snout weevil is a large black beetle that can attack and kill agave plants, and it seems to favor the large century plant, especially as the plant prepares to bloom. Symptoms of Agave Snout Weevil Infestation The most common sign of agave...

Here in the low desert of the Phoenix metro area, we should see our final winter frost in mid-February. That means it's time to fertilize some of your trees just before or as the low desert spring emerges and trees begin to grow or form leaves and blossoms. Why Fertilize Trees Not every tree benefits from fertilizing, but it's essential to add nutrients to the soil for several types of trees you might have in your yard. The soil can only provide so much nutrition to tree roots, and Arizona soil typically lacks the important macronutrients nitrogen and phosphorous and the micronutrient iron, although specific soil makeup varies from one region of the Valley to another. Trees typically need nitrogen (N on your fertilizer ingredient list) for healthy, green leaves and trunk or branch growth. Phosphorus (P) helps stimulate root growth, which is especially helpful for young trees. Phosphorus also...

A new tree is an investment that needs proper care for it to thrive. And if you plant a tree for shade in the hot Arizona desert, you're probably anxious for it to reach mature size. So it’s not surprising that people will do everything they can to get their trees off to a good start. It's common to see people, including landscapers, staking young trees. However, trees seldom need that kind of help. In fact, staking a tree often does more harm than good. Drawbacks of Tree Staking Often, staking ends up damaging a tree, largely because the staking is done improperly or left too long. Staking trees improperly is one of the leading causes of tree death in urban yards. In many cases, the ties attaching a tree to a stake cause girdling, which is cutting through a ring of bark around the entire circumference of the trunk....

Typically, trees go into a period of hibernation during winter's cooler, shorter days, conserving energy by dropping leaves and slowing growth. Still, most trees in our North Phoenix yards need occasional watering during the winter. Reasons to Water Trees in Winter Trees less than one year old need more water than mature trees, regardless whether or not they’re xeric (or “water wise”) trees. An immature tree's root system is actively growing the first year and the roots and tree are more susceptible to injury from lack of water during the winter. Desert trees grow roots in winter in preparation for spring and summer growth. The roots need water to grow, especially during winter’s drier conditions. If you’re growing orange and other citrus trees they’ll need year-round watering to stay healthy, although the amount of water they require in winter is much lower than in other months. See this publication from...

Now that fall has arrived and nighttime temperatures are cooling, it's a great time to plant trees and shrubs in the Phoenix area The moderate fall weather gives tree roots an opportunity to grow and establish in the ground before any chance of winter frost, and without scalding daytime temperatures. Simply put, fall planting gives your trees a better shot at growth and good health. Here are some tips to remember when planting trees to make sure they thrive in the desert sun: Select the Best Tree For Your Area Who doesn’t want fall color in their landscape? But which trees can you plant to give you that color? The key is to choose the trees and shrubs that will thrive in our area while needing less maintenance. For example, you might love the gorgeous fall colors of a Bigtooth Maple ( Acer grandidentatum ) but, while it’s native the...
