Atlantic White Cedar at a glance
| Height | 40-80 ft |
|---|---|
| Spread | 10-25 ft |
| Growth rate | Medium |
| USDA zones | 4-8 |
| Lifespan | Typically 100-200 years, some swamp trees live much longer |
| Type | Evergreen |
| Native range | Coastal swamps and wet sandy soils of the Atlantic and Gulf coasts, from Maine down to northern Florida and west to Mississippi |
| Roots | Shallow and fibrous. The tree grows in wet, acidic, peaty soils, so it tolerates wet feet but does poorly in dry, hot, alkaline soil. |
| Wood | Light, soft, aromatic and very rot-resistant. It has long been used for fence posts, shingles, boat planking and decks. It is not a favorite firewood. |
| Storm risk | mediumThe wood is light and the roots are shallow. Tall trees in wet, soft ground can lean or blow over in strong wind, and old trees can have internal decay. |

Caring for a atlantic white cedar
Best time to prune
Late winter to early spring before new growth, or in summer. Remove dead and damaged branches. Light shaping is fine, and the tree takes a narrow, tidy form on its own.
Avoid pruning
Avoid cutting into bare, leafless wood, since the tree does not regrow from it. Do not shear heavily, and do not top the tree.
More on timing: when to prune trees.
- Plant in moist, acidic soil. It will not do well in dry, alkaline or compacted ground.
- Water deeply and often in the first few years, since the roots are shallow.
- Mulch a few inches away from the trunk, and keep it over the root zone to hold moisture.
- If you live where it is native, check local and state rules before cutting trees in wet areas, since wetland rules may apply. Short explanation, not legal advice.
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 atlantic white cedar
- 1Check wet ground for soft spots before moving equipment in.
- 2Look for brown, dying tops, which can point to root rot or spider mites.
- 3Foliage is flat and scale-like. Plan for fine debris and a lot of chip volume.
- 4Ask about wetland rules when working near swamps or streams.
Removal notes
Trees often grow in wet, soft ground, so truck, crane and stump grinder access can be hard and ruts are common. Plan for mats or an alternate route. Branches are fine and feathery, so expect a lot of chip volume. The wood is light, but a tall tree still needs a controlled drop.
Wood
Light, soft, aromatic and very rot-resistant. It has long been used for fence posts, shingles, boat planking and decks. It is not a favorite firewood.

Atlantic White Cedar: common questions
Is Atlantic white cedar a true cedar?
No. It is in the cypress family, not the true cedar group. It is called a cedar because its aromatic wood is similar to the wood of true cedars.
Where does Atlantic white cedar grow?
It grows naturally in coastal swamps and wet sandy soils along the Atlantic and Gulf coasts. It likes acidic, wet or peaty ground.
Can I plant it in a regular yard?
It can grow in a yard if you keep the soil moist and acidic and give it good drainage and mulch. It is more demanding than common landscape conifers.
Why is my white cedar turning brown?
Common causes are drought, root rot, wet-then-dry swings, and spider mites. Check soil moisture first, then ask an arborist to look at the roots and foliage.
Is the wood really rot-resistant?
Yes. It is known for lasting a long time in contact with weather and water, which is why it was used for shingles, fence posts and boats.
When should an Atlantic white cedar be removed?
Removal is usually a good idea when the tree is dead, leaning with soil lifting, or has a decayed trunk. A certified arborist can inspect it and give written advice. Get two or three written quotes.
