If you’ve been shopping nurseries in late winter and noticed fruit trees with their roots exposed and wrapped in damp packing material, you’ve probably seen bare root trees.
They can look intimidating (and dead) at first—but when planted correctly, bare root trees are one of the best ways to establish healthy, long-lived fruit trees in the Phoenix area.
In this guide, we’ll cover what bare root trees are, why they work so well in our desert climate, and exactly how to plant them correctly in Zone 9b.
What Is a Bare Root Tree?
A bare root tree is sold without soil around the roots. Instead of being grown in a container, the tree is lifted from the field while dormant and stored with its roots kept moist.
Bare root trees:
- Are dormant (not actively growing)
- Are typically available late winter through early spring
- Are most common for fruit trees like apples, peaches, plums, pluots, pears, apricots, and figs
In Phoenix, this timing lines up perfectly with our mild winters and early spring warm-up.
Why Bare Root Trees Are a Great Choice in Phoenix
Bare root trees offer several advantages that are especially valuable in desert soils and high-heat environments:
Less Transplant Shock
Because the tree is dormant, it isn’t struggling to support leaves or fruit while adjusting to new soil.
Faster Root Establishment
Roots grow directly into native desert soil, rather than circling inside a container first.
Easier to Inspect Roots
You can clearly see damaged, girdling, or poorly structured roots before planting—something you can’t do with container trees.
Usually More Affordable
Bare root trees are often less expensive than container trees, making it easier to plant multiple varieties.
Timing Matters (Especially in Zone 9b)
For Phoenix and surrounding areas, timing is critical.
Plant bare root trees only while they are dormant.
- Ideal window: late January through February
- If buds are swelling slightly, you’re still okay
- If leaves have broken out hard, it’s too late
Once daytime temperatures climb quickly (which they do here), dormant planting is no longer safe.
Before You Plant: Prep the Tree
Soak the Roots
Before planting:
- Soak roots in clean water for 1–4 hours
- Never allow roots to dry out
- Do not soak overnight
This rehydrates the tree after storage and transport.
Inspect the Roots
- Trim broken, damaged, or clearly dead roots
- Do not heavily prune healthy roots
- The goal is cleanup, not reduction
How to Plant a Bare Root Tree (The Most Important Part)
Dig a Wide, Shallow Hole
- Hole should be wider than it is deep
- Roots should spread naturally without bending or circling
- Avoid digging a deep “bucket” hole
Find the Root Flare
The root flare is where the trunk widens and transitions into roots.
- The root flare must sit at or slightly above finished soil level
- Never bury the trunk
- In Phoenix, planting too deep is one of the most common causes of long-term tree failure
Backfill with Mostly Native Soil
- Use mostly native soil
- You may add up to 10% compost or amendment, but no more
- Avoid creating a “soil island” that traps roots
Roots need to learn the soil they’ll live in long-term—especially in alkaline desert soils.
Gently Settle the Soil
- Lightly tamp to remove air pockets
- Do not compact aggressively
- Let water do most of the settling
Watering After Planting in Phoenix
Immediately after planting:
- Water deeply to settle soil
- Ensure moisture reaches the full root zone
Ongoing:
- Keep soil consistently moist, not soggy
- Avoid daily watering unless weather conditions truly demand it
- Encourage roots to grow outward and downward, not stay shallow
Deep, infrequent watering is especially important as temperatures rise.
Mulch (But Do It Right)
Mulch is critical in our climate—but it must be done correctly.
- Apply 2–4 inches of mulch
- Keep mulch several inches away from the trunk
- Mulch should resemble a donut, not a volcano
Mulch helps:
- Reduce soil temperature swings
- Retain moisture
- Protect surface roots from extreme heat
What NOT to Do With Bare Root Trees
❌ Don’t plant too deep
❌ Don’t add fertilizer at planting
❌ Don’t stake unless absolutely necessary
Fertilizing at planting can burn roots and delay establishment—especially in Phoenix soils.
What to Expect the First Year
This is where many people get nervous—but it’s normal.
- Minimal top growth is expected
- The tree is investing energy into root development
- Strong roots now mean better fruiting, structure, and heat tolerance later
Patience in year one pays off for decades—and is especially important in our desert climate.
Phoenix Gardeners
Bare root trees are one of the best ways to establish fruit trees in Zone 9b, when planted correctly. The key is respecting dormancy, planting at the correct depth, and working with our native soils instead of against them.
If you get those fundamentals right, bare root trees often outperform container trees long-term in the Phoenix area.
