In other climates, the term “winter interest” often applies to trees with peeling bark, red berries that pop against white snow, or flowers that dry out and create compelling shapes in the landscape. In the Phoenix and Anthem areas, however, it can refer to almost any tree, plant, shrub, cactus, or palm. To narrow it down, we will focus on some trees, shrubs, plants, and wildflowers that provide color or distinction, or may otherwise catch your eye during the winter months. Trees for Winter Interest Changing Leaves We’ve already talked about how “fall” color usually reaches Phoenix during the winter months. (You can read more about that in this article ).

If there has been an active monsoon season (like there has been at the time of this article being written), you might have noticed that your tecoma plants may not look as healthy as they normally do.

We’ve recently had quite a bit of rain in the Phoenix and Anthem areas. Many drought-deciduous trees and plants are thriving after surviving the ongoing drought conditions.

Mesquite trees are just as much a part of our desert environment as the iconic saguaro cactus, quail, coyotes, or any other symbol of life in the southwest. However, they certainly don’t get as much attention.

Lately, we’ve been getting a lot of questions about ironwood trees, and specifically about their spring flowers. Many residents of Anthem and surrounding areas don’t recall ever seeing ironwood trees in bloom. That’s not unusual, but that’s also not the only unique thing about our native ironwood trees.

Some tree issues have unusual names that don’t seem to have anything to do with their name.

Every autumn, leaves throughout much of the country change from green into brilliant hues of red, orange, yellow or burgundy. In the Phoenix area, our low desert climate means that the vibrant fall colors found in cooler climates aren’t as common. But that doesn’t mean we don’t have any bright autumn leaves to admire! When do leaves change color in the Phoenix area? While Northern Arizona, with its higher elevation, sees leaves change during the actual fall season, here in Phoenix the colors change a bit later in the year. It’s not uncommon to see falling leaves next to outdoor Christmas decorations or to see dots of colorful foliage after the new year arrives. While not all trees in our area have leaves that change color, the bright pop of yellow or orange next to our native plants is usually a noticeable change. Look for leaves to change color in...

If you’ve ever noticed a cluster of what appear to be twigs or small branches concentrated together in your mesquite or palo verde tree, it may in fact be desert mistletoe. Mistletoe is often confused for a nest or hive, but it is a living, growing organism. What is desert mistletoe? Desert or mesquite mistletoe ( Phoradendron californicum ) is a hemiparasite that affects many of our local trees. It doesn't look quite like the traditional mistletoe hung in doorways during the holidays, but that's because it's a different variety. There are over 1,000 distinct species of mistletoe worldwide. The scientific classification of mistletoe, Phoradendron , translates to “thief of a tree,” which is a good way to think about mistletoe. It’s not “death of a tree,” per se, but it does rob your tree of certain things. As a hemiparasite, desert mistletoe attaches itself to a tree and steals...

If you’re constantly weeding your Phoenix or Anthem area yard, you may want to consider using a pre-emergent treatment to control the problem. These types of herbicides are applied to stop weed seeds from growing and act very differently from the weed killer sprays used after weeds have emerged.

The answer is in the name – pre-emergent is applied BEFORE weeds appear. This type of liquid herbicide works to prevent weed seeds from growing .

As the long summer months in the Phoenix area drag on, you may notice some of your tree or plant leaves turning brown or dying. Property owners often assume that these brown leaves signal a pest or disease issue. In fact, the most common culprits are much more simple: lack of water, too much salt, or incorrect fertilizer use. Dried or brown leaves may appear to be just a cosmetic issue, but they often signal a bigger problem that should be resolved as quickly as possible. Doing nothing will make your tree more susceptible to opportunistic pests or diseases such as palo verde borers . In this article, we go over each cause and what you can to do prevent or solve them, making your leaves green and vibrant and your tree or plant healthy once more!

When you think of the sounds of summer, one of the most common sounds in the Phoenix and Anthem areas is noise from cicadas. In this article, we go over some common questions about these noisy neighbors, including how they are able to be so loud, if they can damage your trees, and why you generally hear them during the hottest parts of the day.   Are my trees making noise? Summertime in southern Arizona comes with many unique phenomena – monsoons, dust storms, microbursts, flash flooding – and trees that appear to be buzzing or singing. The noisy trees are actually insects called cicadas, cleverly hidden amongst the tree’s branches. Between the projection of their sound, their clever hiding techniques, and their stealthy moves to avoid detection, cicadas are not easily spotted on trees, but they are widely heard. I’ve read about 17-year cicadas, is that what these are?...

Also known as the palo verde beetle, palo verde root borer, or palo verde borer beetle, Derobrachus hovorei is a longhorn beetle that can sometimes be confused as a cockroach. But, unlike cockroaches, this insect attacks and kills palo verde trees (among others). This pest exists as both a grub (or borer) during its immature phase, and a large beetle during it’s adult stage. What does the adult beetle look like?

The adult beetles are brown or black and have wings, but are rarely seen flying other than during the summer mating season. Adult borers have a tough outer shell, which makes them difficult to kill. You’ll notice these large beetles most often during monsoon...

The Texas mountain laurel is a beautiful, evergreen shrub or small tree, with fragrant purple flowers and one noticeable problem – each summer, the plant may suddenly start losing its new leaves and buds.

In this article, we explain what’s happening, what it does to your Texas Mountain Laurel, whether you should be worried about it, and more. Something seems to be eating my Texas mountain laurel.
