Acer palmatum. Also called Palmate maple, Laceleaf maple (dissectum types).
Plain-English notes for homeowners, plus field notes for tree crews. General guidance only: for one specific tree, have a local insured pro look at it.

|---|---|
| Spread | 15-25 ft |
| Growth rate | Slow |
| USDA zones | 5-8 |
| Lifespan | Typically 50-100 years, some live much longer |
| Type | Deciduous |
| Native range | Japan, Korea and parts of China. It is a popular landscape tree across the United States. |
| Roots | Shallow and fibrous, with a gentle spread. It rarely harms buildings, but roots are easy to injure by digging or compacting soil. |
| Wood | Fine-grained, fairly hard, but the branches are thin. It is not commonly used as firewood because the tree is small. |
| Storm risk | lowIt is a small tree, so failures cause little damage. Branches can still break in heavy ice or snow, and thin bark is easy to wound. |
Typical ranges, not guarantees. Soil, water, space and care change how a tree grows. Storm risk is our general rating for the species, not an inspection.

Caring for a japanese maple
Best time to prune
Late fall or winter while dormant, so the branch structure is easy to see, or in summer for light shaping. Thin selectively to show the shape. Remove dead, crossing and rubbing twigs.
Avoid pruning
Avoid heavy cuts and shearing. Japanese maples are valued for their natural form, and large cuts spoil the shape. Avoid pruning in early spring when sap is rising.
More on timing: when to prune trees.
- Give it morning sun and afternoon shade, especially in hot areas. Leaves can scorch in hot, dry wind.
- Plant in well-drained soil. Soggy ground often leads to root rot.
- Water regularly in the first few years and during dry spells, and mulch a few inches away from the trunk.
- Choose a type that fits your zone. Some are less hardy and need shelter in cold areas.
Safety first
Do not climb a tree or use a chainsaw on storm-loaded or broken wood. If a tree or limb is touching power lines, stay away and call the utility. If someone is in danger, call 911. For anything big, hire a local insured pro: read how to hire a tree service and is my tree dangerous?

For tree crews
Field notes: working on japanese maple
- 1Work gently. Thin bark and delicate branches scar easily.
- 2Make small, clean cuts to keep the natural shape. Ask the customer what look they want.
- 3Watch for dieback in one section, which can point to verticillium wilt.
- 4Protect nearby beds and stonework before starting.
Removal notes
These are small trees, so removal is usually quick, but they are often tucked into tight beds near patios and houses. Plan to protect plants, stone and hardscape. Many owners prefer to have a nursery or landscaper transplant a healthy tree instead of removing it.
Wood
Fine-grained, fairly hard, but the branches are thin. It is not commonly used as firewood because the tree is small.

Japanese Maple: common questions
How big does a Japanese maple get?
Many grow 15 to 25 feet tall and wide. Dwarf and weeping types often stay smaller, while some upright types can get taller over time.
Why are the edges of my Japanese maple leaves brown?
Leaf scorch is common. It is usually caused by hot sun, dry wind or too little water. Move or shade the tree and water deeply during dry weather.
When should I prune a Japanese maple?
Late fall to winter is best for shaping, since the branches are bare. Light summer pruning is also fine. Avoid heavy cuts.
Can a Japanese maple grow in full sun?
It can in cooler areas, but in hot places it usually does better with some afternoon shade. Red-leaf types may fade to green in deep shade.
Why did one branch of my Japanese maple die?
Possible causes include root problems, winter injury, canker or verticillium wilt. If more than one branch dies, ask an arborist to check.
Can a Japanese maple be moved?
Small trees often can be moved in the dormant season with a good root ball. Larger trees are harder, so a nursery or arborist can advise.
