How To
Curious how tall can a mulberry tree grow before it towers over your backyard? These fast-growing 🌳 giants can stretch up to 60 feet if left unchecked—but don’t worry, there are ways to keep them in check while still enjoying their sweet fruit.
Whether you're dreaming of a towering shade provider or a compact backyard tree, choosing the right variety makes all the difference. Some mulberries stay under 25 feet, while others shoot up like skyscrapers. The key? Pruning and spacing from day one.
I’ll show you the fastest-growing varieties and space-saving tricks to keep your mulberry tree at your ideal height—whether that’s a 15-foot dwarf or a 30-foot standard. Plus, I’ll share how to plan for overhead clearance so your tree doesn’t become a backyard nuisance.
Ready to grow a mulberry tree that fits your space? Let’s dive into the varieties, pruning tips, and practical advice you need to keep it under control—without sacrificing those juicy berries.
Mulberry tree height by variety: fastest-growing types and their maximum heights
Mulberry trees are fast growers that can reach 60 feet if unchecked, but their height varies dramatically by variety. The Illinois Everbearing mulberry, for example, is one of the fastest-growing types, shooting up 10 feet per year in ideal conditions. Meanwhile, dwarf varieties like Texas Mulberry stay under 15 feet, making them perfect for small yards.
If you're planting near power lines or tight spaces, pruning early is key. Even standard varieties can be trained to stay 20-30 feet tall with consistent maintenance. Below, I’ve compared the most popular mulberry types—from towering giants to compact backyard options—so you can pick the perfect fit for your space.
🌱
| Variety | Mature Height | Growth Rate | Best For |
|---|---|---|---|
| Illinois Everbearing | 30-60 ft | 10+ ft/year | Large yards, shade |
| Texas Mulberry | 15-25 ft | 5-8 ft/year | Small yards, containers |
| Black Mulberry | 40-60 ft | 8-12 ft/year | Large properties, fruit production |
| Red Mulberry | 25-40 ft | 6-10 ft/year | Medium yards, wildlife |
| Dwarf Mulberry | 10-15 ft | 3-5 ft/year | Urban gardens, patios |
For fastest growth, the Illinois Everbearing mulberry is unbeatable, but its 60-foot potential means it’s best for rural settings. If you’re in a suburban neighborhood, the Texas Mulberry or dwarf varieties are far more manageable while still delivering sweet fruit. Always check local overhead clearance laws—some areas require permits for trees over 30 feet.
Climate also plays a role: mulberries thrive in USDA Zones 5-9, but their growth rate slows in colder regions. In warmer zones like Zone 9, expect 10+ feet of growth per year if conditions are ideal. If you’re in a cooler zone, growth may be slower, but pruning can still keep the tree at a desired height.
Pro tip: Plant your mulberry tree at least 20 feet from structures, fences, or power lines. Even dwarf varieties can spread 15-20 feet wide with their roots and branches. If space is tight, consider espalier training—this method turns a tree into a wall-mounted fruit producer while keeping its height in check.

When selecting a mulberry, think about your long-term goals. Do you want a shade tree, a fruit producer, or both? The Black Mulberry is a top pick for fruit, while the Texas Mulberry is more drought-tolerant. For urban gardeners, the dwarf variety is a game-changer—it fits in small spaces without sacrificing flavor.
One mistake I see often is underestimating a mulberry’s root spread. These trees develop extensive root systems that can damage sidewalks or foundations if planted too close. Always dig a wide planting hole (3x wider than the root ball) and amend the soil with compost to encourage healthy root growth outward instead of downward.

Pruning techniques to control mulberry tree height and shape
Pruning is the secret weapon for keeping your mulberry tree at a manageable height while boosting fruit production. Unlike many trees, mulberries respond well to heavy pruning—you can safely remove up to 30% of its canopy annually without harm. The key is timing: prune during late winter or early spring, just before new growth begins. This ensures your cuts encourage vigorous, bushier growth rather than weak, late-season shoots.
For height control, focus on crown thinning—this means selectively removing branches from the top third of the tree to reduce its overall height while improving airflow. I recommend starting this process when your tree reaches 10-12 feet tall. Even the fastest-growing varieties like the Illinois Everbearing can be kept under 25 feet with consistent thinning. Use sharp, clean pruners to make cuts just above outward-facing buds to encourage new growth in the right direction.
🌱
- 1 Identify the Target Height: Measure your desired height (e.g., 15 feet for a small yard) and mark it with a flag or string for reference.
- 2 Remove Vertical Branches: Cut out straight-up branches (called "water sprouts") that contribute to height but not width. These grow from the trunk or main limbs.
- 3 Thin the Canopy: Selectively remove 1-2 older branches from the tree’s center to improve light penetration. Aim for branches that are thicker than a pencil to avoid over-thinning.
- 4 Head Back Overgrown Branches: Cut the top 1/3 off of overly long branches to encourage bushier growth. Make cuts just above a side bud or branch junction.
- 5 Shape the Tree: Use pruning to create a natural, balanced shape. Avoid cutting too much from one side, which can cause uneven growth. Step back frequently to visualize the tree’s form.
- 6 Clean Up Debris: Remove all pruned branches and sterilize tools with rubbing alcohol to prevent disease. Rake up fallen leaves and twigs to keep the base of the tree clean.
If your mulberry tree is already too tall, don’t panic—gradual pruning over 2-3 years can bring it down safely. For example, if your tree is 25 feet tall but you want it at 15 feet, reduce its height by 3-5 feet per year. This prevents shock and allows the tree to recover. Always prune on a dry, calm day to avoid spreading disease through fresh cuts.
For extra-compact growth, try espalier training, a method where you train the tree to grow flat against a wall or fence. This isn’t just for aesthetics—it’s a space-saving hack! By pruning and tying branches horizontally, you can keep a mulberry tree under 10 feet tall while still producing fruit. Just be patient: espalier takes 2-3 years to establish, but the results are worth it for urban gardeners.
One common mistake is pruning too late in the season. Avoid cutting back mulberry trees after mid-summer, as new growth won’t harden off before winter. Late pruning can leave your tree vulnerable to cold damage or pest infestations. Stick to late winter or early spring for best results, and you’ll see healthier, more controlled growth every year.
