The sissoo tree is originally from the subtropical areas of India, Nepal, and Pakistan. But due to Arizona having a similar climate, this invasive specie thrives in the Copper State. Some Arizonans love sissoo trees, while others detest them. We’ll discuss whether you should grow a Sissoo Tree in Arizona and show you both sides of the argument.
Reasons to Plant a Sissoo Tree in Arizona
Below are some of the most common reasons people plant sissoo trees in their yard.
1. Provides Shade
Unlike many trees in Arizona, the sissoo offers an immense amount of shade, thanks to its dense leaves. Its oval, leathery leaves tolerate Arizona’s intense sun well, giving you a cool place to have a family picnic.
Although sissoo trees don’t have large leaves, their dense nature makes this tree an excellent fit for Arizonans seeking respite from the summer heat.
2. Ideal for Arizona’s Climate
Sissoo trees have an excellent drought tolerance. As a result, you won’t need to spend money keeping these trees watered, and they can thrive in even the most nutrient-deficient soil.
Although sissoo trees prefer hot weather, they can withstand cold temperatures up to a light frost. So, they’re an ideal tree for Arizona winters in areas that don’t drop below zero.
3. Attractive Appearance
Many trees and shrubs native to Arizona have low-lying canopies and wispy leaves. But sissoo trees have a unique appearance, boasting light brown bark with a shaggy appearance and solid leaves with a leathery texture.
Sissoo trees also have a notably dark green color compared to the lighter green-ish brown leaves on many native plants.
4. Fast Grower
Sissoo trees grow over two feet per year, making them exceptionally fast growers. Therefore, they’re an excellent fit for people wanting a natural tree hedgerow in Arizona.
You can expect your sissoo trees to grow as high as 50 to 60 feet with a 30 to 40-foot spread. It usually isn’t necessary to prune sissoo trees. However, some pruning can be beneficial to keep low-lying branches from hanging on the ground as the tree grows.
Reasons To Reconsider Planting a Sissoo Tree in Arizona
Before planting a sissoo tree, it’s essential to understand its downsides.
1. Consumes Lots of Water
Sissoo trees require excessive amounts of water compared to many native Arizona plants. It’s no secret that Arizona is struggling with its water supply; six cities in Arizona have already announced water shortages due to dry conditions in the Colorado River.
Thanks to their deep and sprawling root system, sissoo trees are independent water seekers. Adult trees have 40-foot roots for finding water.
2. Uplifts Foundation
The fact that a sissoo tree’s roots can travel so far makes it challenging for homeowners. If a sissoo tree is too close to homes, sidewalks, roads, and other structures, its roots can crack foundation, concrete, and pavement.
For this reason, should you choose to plant a sissoo tree, it’s vital to do so far away from artificial structures.
3. Seeds Create a Mess
Sissoo trees are bountiful reproducers, growing three-inch pods that hold their seeds. Unfortunately, these seeds can create a mess in your yard when they fall from the tree, so you’ll need to rake frequently.
Furthermore, the seeds can quickly take root. Many people need to use an herbicide to prevent already rooted seeds from continuing to grow back—a common situation even if you cut a Sissoo tree down to its stump.
The Bottom Line
Arizonans have a love-hate relationship with sissoo trees. While sissoo trees have advantages, if you plant them, be sure to rake up their seedpods and remove unwanted new sissoo growth to prevent this invasive species from spreading to your neighbors’ lawns.
