Did you know that what you plant today has short-term and long-term benefits? It’s true. As water resources become even more precious, planting wisely is more important than ever. You will enjoy the immediate effects of lowering your outdoor water use while enjoying the knowledge that you are creating a sustainable outdoor space for the future.

Another benefit is that low-water plants are beautiful and increase your outdoor enjoyment.

So, let’s discuss four ways of “planting ahead” to ensure that your desert landscape is resilient for years to come.

Plant More Shade

The benefits of shade in the garden cannot be overstated; trees are a great way to achieve that. Trees offer a welcome respite from the hot desert sun while adding beauty to the landscape. Additionally, trees reduce outdoor temperatures underneath their branches, and when placed on the west, east, or south side of your home, will save money on energy bills.

Native and desert-adapted trees don’t use much water, and plants grown under the branches of trees use less water than those planted in full sun.

Look at the areas around your home and see if there are areas where shade be added. If you have a narrow space where trees won’t fit, consider using tall shrubs such as hop bush (Dodonaea viscosa) to provide shade.

Plant More Color

People are naturally drawn to color, and you can improve your home’s curb appeal by adding colorful plants. Desert dwellers have many flowering plants to choose from – from groundcovers, shrubs, and vines. Additionally, we have a year-round growing climate so you can always have something in bloom outdoors.

To maximize the color impact of plants, group the same plants together in threes or fives instead of just one. Place colorful plants in high-visibility areas such as against a wall, the corners of your property, and near the front entry where they are sure to be seen.

Avoid the biggest color mistake and stop excessively pruning flowering plants into unnatural shapes. Most flowering shrubs need pruning once a year or less.

Plant More Wildlife

Our gardens can help benefit wildlife by providing food and shelter. A bonus is that you get to view them up close! The easiest way to invite wildlife such as birds, bees, and butterflies is to incorporate plants they are attracted to.

Trees, shrubs, and even cacti can provide shelter, while the blooms from certain plants will provide nectar and seeds. One easy way to encourage pollinators to visit your garden is to replace thirsty flowering annuals in containers and plant flowering shrubs instead. The shrubs will use less water while still providing you with color. 

Baja fairy duster (Calliandra californica) is one of my favorite choices for attracting pollinators such as butterflies, hummingbirds, and larger bird species are attracted to the seeds.

Plant More Water Saving

Plants don’t use the same amount of water – some need more, while others do fine receiving less while still looking great. You don’t need a yard filled with thirsty plants because many beautiful plants use less water (and I’m not just speaking of cacti and succulents). 

Switch out high-water-use plants and replace them with those that need less water. Groundcovers are an excellent substitute for a lawn – particularly decorative ones. Many low-growing groundcovers have lush green foliage but require a fraction of the water that a lawn does. While they can’t be walked upon, they make a beautiful addition to the landscape, and many add a colorful element and provide a food source for pollinators. Even better, they require very little maintenance.

Planting ahead involves strategically selecting the plants we choose for our desert landscapes. These four ideas will help you create a beautiful yet sustainable outdoor space that will save water and provide a more sustainable future.

For quite some time, I’ve been considering writing this post. I’ve hesitated due to the overwhelming affection people have for ficus trees (Ficus nitida). While the benefits of planting ficus trees are apparent. They have lush beauty and dense shade that are particularly valuable in desert environments. There are a few considerations to bear in mind before incorporating them into your landscape.

At first, the benefits of planting a Ficus tree are obvious. They are lush, beautiful and provide dense shade, which is sometimes scarce in the desert.

The Pros and Cons of Ficus Nitida Trees: What You Need to Know

So what’s the problem with having a Ficus tree? Well, there are a couple of things that you should be aware of before you plant a Ficus tree.

One of the primary challenges with Ficus trees is their vulnerability to frost damage. This is especially concerning in low desert regions when temperatures drop below freezing. This concern becomes even more pronounced during stretches of consecutive freezing days.

This past winter, we experienced a three-day period of temperatures in the low 20s. The impact on local Ficus trees was unmistakable. A mere drive through any neighborhood allowed me to distinguish, even from a distance, who had Ficus trees and who did not. The extensive presence of ‘brown’ trees gave it away.

After the return of warmer weather, many Ficus trees sported trimmed branches. This results in a shorter appearance due to frost damage mitigation (see image below).

Growth Size and Control

The second challenge stems from insufficient research regarding the potential size of Ficus trees. Individuals often find themselves ill-prepared when the charming shade tree they planted rapidly becomes an overwhelming presence. Trees often seem to engulf their homes.

What to Consider When Planting Ficus Trees

If your heart is set on having a Ficus tree grace your garden, go ahead and acquire one. Just remember that some winters might result in frost damage, temporarily affecting the tree’s appearance until new branches emerge. To ensure a successful experience with Ficus trees, keep the following points in mind:

  1. Proper Placement: Exercise caution when choosing a planting spot. Allow ample space for the tree to reach its mature dimensions without infringing on your house. Additionally, avoid planting near patios and pools, as the tree’s shallow roots can pose problems with insufficient watering. Ficus trees can attain heights of 30 to 50 feet and widths of 40 feet.
  2. Alternatives to Consider: While sissoo trees (Dalbergia sissoo) might appear to be an attractive alternative to Ficus, they also come with their own set of considerations.

Sissoo Trees as an Alternative

Sissoo trees, resembling Ficus trees in appearance, exhibit greater frost tolerance. Despite their appealing features, it’s crucial to exercise caution when integrating sissoo trees into your landscape.

Some people look to sissoo trees as an alternative to ficus – BUT, this isn’t advisable either.

The sissoo tree (Dalbergia sissoo) is similar in appearance to the ficus tree. They do however have greater tolerance to frost.

Like ficus trees, sissoo trees do grow quite large but I no longer recommend them for average size residential landscapes. The photo of the tree above was taken four years after it was planted from a 15-gallon container. It rapidly grew even larger.  This tree made it’s debut in the Phoenix area about 15 years ago. It has become quite popular for its lush green beauty.

While sissoo trees flourish in larger outdoor areas such as parks due to their enhanced frost resilience, they present potential challenges for average-sized residential landscapes. Despite their initial popularity for their lush green beauty, their invasive root systems can wreak havoc on sidewalks, patios, pools, and block walls. Moreover, their eventual size can dwarf the landscapes they were intended to enhance.

Careful Planning is the Best Approach for Ficus or Sissoo Tree Placement

The allure of Ficus nitida trees is undeniable, but careful planning and consideration are necessary to ensure a harmonious coexistence between these magnificent trees and your landscape. Understanding their susceptibility to frost damage and their potential for significant growth is vital for making informed decisions.

While sissoo trees can be a reasonable alternative, they too come with their own set of challenges that need to be weighed carefully. Ultimately, choosing the right tree for your outdoor space involves a blend of appreciation for aesthetics and awareness of practicality.
