Our Top Picks: The Best Fast Growing Trees in AZ

Alright, this is the fun part! I’ve worked with countless trees over the years here in the desert, and I’ve learned which ones are the true champions of rapid growth and which ones can’t handle the heat. This isn’t just a list; it’s a curated selection of proven winners for Arizona yards.

1. Desert Museum Palo Verde (Parkinsonia ‘Desert Museum’)

If there’s a superstar of the desert, this is it. The Desert Museum is a hybrid that takes the best qualities of its parents—it’s fast-growing, thornless, and produces a spectacular display of brilliant yellow flowers in the spring. Its light, filtered shade is perfect for underplanting with other desert-friendly species.

  • Growth Rate: 3-4 feet per year.
  • Mature Size: 25-30 feet tall and wide.
  • Water Needs: Very low once established. Deep watering every few weeks in summer is plenty.
  • Pro Tip: Avoid the temptation to overwater! This tree thrives on a bit of neglect.

2. Tipu Tree (Tipuana tipu)

For those seeking a more traditional, lush, umbrella-shaped canopy, the Tipu tree is a fantastic choice. It provides dense shade and puts on a beautiful show of apricot-yellow flowers in late spring. It’s a thirsty tree compared to a Palo Verde, but its growth rate is truly impressive.

  • Growth Rate: 3-5 feet per year.
  • Mature Size: 25-40 feet tall, with a wider spread.
  • Water Needs: Moderate. Requires regular, deep watering, especially during the first few years.
  • Heads Up: It can have a somewhat aggressive root system, so plant it at least 15-20 feet away from foundations, pools, and sidewalks.

3. Willow Acacia (Acacia salicina)

I adore the graceful, weeping form of the Willow Acacia. It provides a soft, elegant look that’s different from many other desert trees. It’s incredibly tough, handling both intense sun and chilly winter nights with ease. It’s a great choice for a fast-growing, low-maintenance screen.

  • Growth Rate: 2-4 feet per year.
  • Mature Size: 20-40 feet tall.
  • Water Needs: Low. It’s very drought-tolerant once it gets its roots down.
  • Garden Friend: Its non-invasive roots make it a safer choice for planting closer to patios or walkways than other fast-growers.

4. Chinese Elm (Ulmus parvifolia)

Often called the “Lacebark Elm,” this is a tough, adaptable, and beautiful shade tree. Its attractive, mottled bark provides year-round interest. It can handle our alkaline soil and scorching sun like a champ, providing wonderful, dense shade faster than almost any other non-native tree.

  • Growth Rate: 3-5 feet per year.
  • Mature Size: 40-50 feet tall.
  • Water Needs: Low to moderate. Benefits from consistent watering for faster growth but is quite drought-tolerant.
  • Best Practice: Ensure you get the true Ulmus parvifolia, not the inferior and problematic Siberian Elm which is often mistakenly sold.

5. Arizona Ash (Fraxinus velutina)

A classic native shade tree, the Arizona Ash is a deciduous tree that provides dense summer shade and then lets the warm winter sun through after dropping its leaves. It’s a reliable and popular choice, especially in established neighborhoods throughout Phoenix and Tucson.

  • Growth Rate: 2-3 feet per year.
  • Mature Size: 30-40 feet tall and wide.
  • Water Needs: Moderate. It does best with consistent moisture and isn’t as drought-tolerant as desert natives.
  • A Note: It can be prone to certain pests, so keeping it healthy with proper watering is key to its defense.

How to Plant Fast Growing Trees in AZ: A Step-by-Step Guide

Knowing how to fast growing trees in az starts with a successful planting day. Don’t worry—this is easier than you think! Giving your new tree the right start is the most important thing you can do to ensure a long, healthy life. Follow these steps, and you’ll be a pro.

Step 1: Choose the Perfect Location

Before you dig, look up and look around. Consider the tree’s mature size. Will it interfere with power lines? Is it too close to your house foundation or your pool? Give it room to grow into its glorious final form.

Step 2: Dig the Right Hole

This is a classic rookie mistake, but you’re going to get it right! The rule is simple: dig the hole two to three times as wide as the root ball, but only just as deep. Planting a tree too deep is one of the quickest ways to doom it. The spot where the trunk flares out to meet the roots should be slightly above ground level.

Step 3: Planting and Backfilling

Gently remove the tree from its container and inspect the roots. If they are tightly circled, gently tease them apart with your fingers. Place the tree in the center of the hole. Use the native soil you dug out to backfill around the root ball. There’s no need to add a lot of amendments directly into the hole; it’s better to amend the soil on top later.

Step 4: Water Deeply and Mulch

Create a small basin or berm of soil around the edge of the planting hole. This will hold water and direct it straight to the roots. Now, water it slowly and deeply, letting the water soak in completely. Finish by applying a 2-3 inch layer of organic mulch (like wood chips) over the entire area, but be sure to keep it a few inches away from the trunk itself.

Your Fast Growing Trees in AZ Care Guide

You’ve planted your tree—congratulations! Now comes the easy part: a little bit of consistent care. This simple fast growing trees in az care guide will keep your tree happy and growing strong.

Watering Wisely: The Secret to Strong Roots

In the desert, we water deeply and infrequently. This encourages the tree’s roots to grow deep into the soil in search of moisture, making it much more stable and drought-tolerant. For a new tree, water every few days for the first couple of weeks, then transition to once a week, and eventually to every 2-4 weeks in the summer once it’s established (usually after 1-2 years).

Fertilizing Your Tree

Most desert-adapted trees don’t need much fertilizer. Our native soils are often sufficient. If you notice yellowing leaves or slow growth after the first year, a balanced, slow-release fertilizer applied in the spring can give it a boost. But don’t overdo it!

Pruning for a Strong Structure

Fast-growing trees can sometimes develop weak branches. The goal of pruning is to create a strong central leader (the main trunk) and well-spaced branches. In the first few years, remove any crossing, broken, or weak V-shaped branches. It’s one of the most important fast growing trees in az best practices to prevent storm damage later on.

Common Problems with Fast Growing Trees in AZ (and Pro Solutions)

Being an expert means knowing the potential pitfalls, too. While fast-growers are amazing, they come with a few things to watch out for. Here are the most common problems with fast growing trees in az and how to handle them.

  • Problem: Weak Wood. Because they grow so quickly, the wood of some species can be more brittle and susceptible to breaking in our monsoon storms.
    • Solution: Proper structural pruning when the tree is young is your best defense. Don’t wait until it’s a huge problem.
  • Problem: Invasive Roots. Some fast-growing trees, like the Sissoo tree, have incredibly aggressive root systems that can destroy pavement, pools, and foundations.
    • Solution: Do your research! Choose trees with less aggressive roots (like Willow Acacia or Palo Verde) or plant known offenders far, far away from any structures.
  • Problem: Sun Scald. Young trees with thin bark can get sunburned on their trunks, especially on the south and west sides.
    • Solution: You can protect the trunk for the first couple of years by painting it with a 50/50 mix of white latex paint and water or by using a commercial tree wrap.
