| Spread | 40-50 ft |
| Growth rate | Slow to medium |
| USDA zones | 3-8 |
| Lifespan | Typically 100-150 years, some live longer |

For homeowners
Caring for a kentucky coffeetree
Best time to prune
Late fall through winter while dormant, or in summer. Train young trees to one strong central leader. The tree needs little pruning once it has a good shape.
Avoid pruning
Avoid heavy pruning in spring when sap flow and new growth are active. Do not top the tree. Avoid big wounds on young trees, because the coarse branches close wounds slowly.
More on timing: when to prune trees.
- Seed pods are large, hard and messy. Choose a male tree, which makes no pods, if you can find one.
- The pods, seeds and leaves contain harmful compounds. Keep children and pets from eating them.
- Expect late leaf-out in spring and early leaf drop in fall. Bare branches in winter are normal and give the tree a bold shape.
- It tolerates hard sites well, so it is a good tough tree for streets and parks.
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 kentucky coffeetree
- 1Expect heavy pieces and plan rigging with good friction and strong anchors.
- 2Large leaves, twigs and pods drop in different seasons. Plan cleanup scope for each job.
- 3Watch for old pruning wounds and cracks at forks, since coarse branches close wounds slowly.
- 4Flag pods and seeds as hazardous to eat when you talk to the homeowner.
Removal notes
Wood is heavy and dense, so sections are heavy to lower and haul. The coarse branches have few twigs, so branch weight is concentrated in the big limbs. Seed pods can litter the ground and should be raked up. Pods and seeds are harmful to eat, so tell the customer to keep children and pets away.
Wood
Hard, strong and heavy, with a reddish-brown heartwood. It makes good firewood once dried and has been used for furniture and fence posts.

Kentucky Coffeetree: common questions
Can you really make coffee from a Kentucky coffeetree?
People have roasted the seeds as a coffee substitute in the past, but raw seeds, pods and leaves contain harmful compounds. Do not eat them. Keep children and pets away.
Why does my coffeetree have no leaves in spring?
This tree is one of the last to leaf out in spring and one of the first to drop leaves in fall. Bare branches into late spring are normal.
Are the seed pods a problem?
Female trees drop large, hard pods that can be messy and may be harmful if eaten. Male trees do not make pods, so many growers prefer them.
Is it a tough street tree?
Yes. It tolerates drought, heat, cold, compacted soil and some road salt, and it has few serious pest problems.
How fast does it grow?
It grows slowly to moderately, typically about 1 to 2 feet a year when young. It lives a long time and develops strong wood.
When does a coffeetree need to be removed?
Removal is usually a good idea when the tree is dead, badly decayed, cracked or a hazard to a building. A certified arborist can inspect it and give written advice. Get two or three written quotes.
