Mulberry trees can tower up to 80 feet in their natural habitat, though cultivated varieties often stay much shorter. If you’re wondering how tall do mulberry trees grow in your backyard, the answer depends on the species, pruning, and growing conditions. This guide breaks down everything you need to know about mulberry tree height, from wild giants to compact cultivars.
How Tall Do Mulberry Trees Grow
Mulberry trees come in three main species, each with a different height range. The red mulberry (Morus rubra) is the tallest, reaching 50 to 80 feet in the wild. White mulberry (Morus alba) grows 30 to 60 feet tall, while black mulberry (Morus nigra) stays smaller at 20 to 40 feet. Cultivated varieties, especially dwarf or weeping types, rarely exceed 15 to 20 feet.
Your tree’s final height also depends on climate, soil quality, and how you prune it. In rich, moist soil with full sun, mulberries grow faster and taller. Poor soil or heavy shade stunts their growth.
Red Mulberry Height Details
Red mulberry is native to eastern North America. It grows fast in its first 10 years, adding 2 to 3 feet per year. Mature trees often hit 60 feet, but some reach 80 feet in ideal conditions.
- Typical height: 50–70 feet
- Maximum recorded: 80 feet
- Growth rate: 2–3 feet per year
- Canopy spread: 40–50 feet
Red mulberrys have a broad, rounded crown. Their height makes them unsuitable for small yards unless you prune regularly.
White Mulberry Height Details
White mulberry, native to China, grows 30 to 60 feet tall. It adapts well to urban environments and poor soil. In cities, it often stays shorter due to space limits and pruning.
- Typical height: 30–50 feet
- Maximum recorded: 60 feet
- Growth rate: 1.5–2.5 feet per year
- Canopy spread: 30–40 feet
White mulberry has a more upright shape than red mulberry. It’s common in parks and along streets, but its aggressive roots can cause problems near sidewalks.
Black Mulberry Height Details
Black mulberry is the smallest of the three, topping out at 20 to 40 feet. It grows slowly and has a bushy, spreading habit. This species is popular in home gardens because it stays manageable.
- Typical height: 20–30 feet
- Maximum recorded: 40 feet
- Growth rate: 1–2 feet per year
- Canopy spread: 25–35 feet
Black mulberry produces the sweetest fruit, but it’s less cold-hardy than red or white varieties. It thrives in warm climates.
Dwarf And Weeping Mulberry Heights
If you have a small yard, dwarf mulberry trees are your best bet. These cultivars stay under 15 feet tall. Weeping mulberries, like ‘Pendula,’ grow only 6 to 10 feet tall with a cascading form.
Popular Dwarf Cultivars
- ‘Dwarf Everbearing’: 8–12 feet tall
- ‘Gerardi Dwarf’: 6–10 feet tall
- ‘Illinois Everbearing’: 10–15 feet tall
- ‘Pakistan Mulberry’: 15–20 feet tall (semi-dwarf)
These compact trees produce full-sized fruit. They’re ideal for containers, small gardens, or espalier training. You can keep them even shorter with annual pruning.
Weeping Mulberry Height
Weeping mulberry (Morus alba ‘Pendula’) grows 6 to 10 feet tall with a 10 to 15 foot spread. Its branches droop gracefully, creating a umbrella-like shape. This variety rarely needs pruning for height control.
Weeping mulberries are grafted onto standard rootstocks. The graft union affects final height—some reach 12 feet if the rootstock is vigorous.
Factors That Affect Mulberry Tree Height
Several factors determine how tall your mulberry tree will grow. Understanding these helps you predict and control its size.
Climate And Hardiness Zones
Mulberries grow best in USDA zones 4 through 9. In colder zones (4–5), trees stay shorter due to winter dieback. In warmer zones (7–9), they reach maximum height.
- Red mulberry: zones 4–8
- White mulberry: zones 3–9
- Black mulberry: zones 5–9
Frost damage in spring can stunt growth. If you live in a cold area, choose a hardy species like white mulberry.
Soil And Water
Mulberries prefer well-drained loamy soil with a pH of 5.5 to 7.0. Rich soil with organic matter promotes faster growth. Sandy or clay soil slows height gain.
Consistent watering during the first 3 years helps roots establish. Once mature, mulberries are drought-tolerant but grow taller with regular moisture.
Sunlight
Full sun (6–8 hours daily) is essential for maximum height. Trees in partial shade grow slower and stay 10 to 20 feet shorter. They also produce less fruit.
Pruning Practices
Pruning is the most effective way to control height. You can keep a 50-foot species at 20 feet with annual pruning. Here’s how:
- Prune in late winter while the tree is dormant.
- Cut the central leader back to a lateral branch.
- Remove vertical shoots (water sprouts) in summer.
- Thin the canopy to reduce overall height.
Without pruning, mulberries grow to their natural size. Regular pruning keeps them compact and easy to harvest.
Mulberry Tree Growth Rate
Mulberries are fast-growing trees. They add 2 to 3 feet per year in ideal conditions. Some reach 30 feet in 10 years. Here’s a timeline:
- Year 1: 2–4 feet tall (from sapling)
- Year 3: 8–12 feet tall
- Year 5: 15–20 feet tall
- Year 10: 25–35 feet tall
- Year 20: 40–60 feet tall (species dependent)
Growth slows after 20 years. Most trees reach 90% of their final height by age 25.
How To Measure Mulberry Tree Height
You can estimate your tree’s height without climbing. Use these methods:
Shadow Method
- Measure the tree’s shadow length on flat ground.
- Measure your own shadow length.
- Divide tree shadow by your shadow.
- Multiply by your height.
Example: Tree shadow is 30 feet, your shadow is 5 feet, you’re 6 feet tall. 30 ÷ 5 = 6. 6 × 6 = 36 feet tree height.
Stick Method
- Hold a stick vertically at arm’s length.
- Walk backward until the stick appears as tall as the tree.
- Measure the distance from you to the tree base.
- That distance equals the tree height.
These methods give rough estimates. For precise measurement, use a clinometer or hire an arborist.
Mulberry Tree Height Vs. Spread
Height isn’t the only dimension to consider. Mulberry trees have wide canopies that match or exceed their height. A 50-foot tree often spreads 40 to 50 feet.
- Red mulberry: height 50–70 ft, spread 40–50 ft
- White mulberry: height 30–50 ft, spread 30–40 ft
- Black mulberry: height 20–30 ft, spread 25–35 ft
- Dwarf cultivars: height 8–15 ft, spread 10–15 ft
Plan for both height and spread when planting. Give your tree enough space to avoid crowding buildings or power lines.
Mulberry Tree Height In Containers
Growing mulberries in pots limits their height. Container trees stay 30 to 50 percent smaller than ground-planted ones. Dwarf varieties in large pots reach 6 to 10 feet.
Use a 15- to 20-gallon pot for best results. Prune roots every 2 to 3 years to prevent them from circling. Container trees need more frequent watering and fertilizing.
Common Height-Related Problems
Tall mulberry trees can cause issues. Here are the most common ones:
Root Damage
Large mulberries have aggressive roots that spread wide. They can crack sidewalks, foundations, and driveways. Keep trees at least 20 feet from structures.
Fruit Drop
Tall trees drop fruit from high branches, creating mess and attracting pests. Prune to keep fruit within reach. Dwarf varieties reduce this problem.
Wind Damage
Mulberries have brittle wood. Tall trees in exposed areas may lose branches in storms. Regular pruning reduces wind resistance.
Frequently Asked Questions
How Tall Do Mulberry Trees Grow In 5 Years?
In 5 years, most mulberry trees reach 15 to 20 feet tall. Dwarf varieties stay under 10 feet. Growth depends on species, soil, and care.
Can You Keep A Mulberry Tree Small?
Yes, regular pruning keeps mulberries small. Cut back the leader and thin branches annually. Dwarf cultivars need less pruning to stay compact.
How Tall Do Weeping Mulberry Trees Grow?
Weeping mulberries grow 6 to 10 feet tall. Their cascading branches spread 10 to 15 feet wide. They’re grafted onto standard rootstocks.
Do Mulberry Trees Stop Growing?
Mulberries slow down after 20 years but don’t stop completely. They add 6 to 12 inches per year in maturity. Most reach final height by age 25.
How Tall Do Mulberry Trees Grow In Pots?
Container mulberries stay 30 to 50 percent shorter than ground trees. Dwarf varieties in pots reach 6 to 10 feet. Use a large pot for best results.
Final Tips For Managing Mulberry Height
Choose the right species for your space. Dwarf or weeping varieties work best for small yards. Plant red or white mulberries only if you have room for a large tree.
Prune annually to control height. Start pruning when the tree is young to shape its growth. Remove dead or crossing branches to maintain health.
Monitor growth in the first 10 years. Mulberries grow fast, so check height each spring. Adjust pruning as needed to keep the tree manageable.
With proper planning, you can enjoy a mulberry tree at any height. Whether you want a 80-foot shade tree or a 8-foot fruit producer, there’s a variety for you.
