Other dogwood tree diseases and pests include: Basal trunk canker Mistletoe Root rot Powdery mildew Sooty mold Many of these insect and disease conditions can weaken the tree and lead to tree death if not treated. If you suspect a problem with your trees, call a SavATreecertified arboristright ...
Mulch around the tree, about 3-4 inches thick. Spread the mulch evenly in a circle extending 2-3 feet from the trunk. Don’t let the mulch touch the trunk–keep a finger width or two separation. The final mulch job should look like a flattened donut, not a volcano. Growing How to ...
(a) A tree of the genus Amyris (A. balsamifera) found in the West Indies, from the trunk of which a black liquor distills, supposed to have poisonous qualities. (b) The poison sumac (Rhus venenata). [U. S.] Poison dogwood (Bot.), poison sumac. Poison fang (Zo["o]l.), one ...
Pests and Diseases The Dogwood is currently at risk for both fungus and pest infestations, which is why it is important to buy the sapling from an arborist instead of transplanting the tree from the wild. Dogwood anthracnose is a disease caused by the fungus Discula destructiva. For this reas...
The most common insect pest is the dogwood borer, whose larvae burrow under the bark of the trunk and limbs. Because newly hatched larvae enter the tree through wounds or broken bark, avoid damage to the bark when doing lawn maintenance and don't prune from April to June when borers are ...
These trees grow best in a partial shade environment, growing up to 30 feet in height with a 20-foot spread at maturity. Flowering dogwood prefers growing on rich, well-draining soils that are moist, so regular watering benefits the tree's growth and flowering. ...
Add a 3-inch layer of mulch to the soil around the dogwood tree. Prune any suckers (small shoots) that sprout from the trunk below the graft union (swollen area on the lower portion of the tree where it was grafted onto stock). These can generally be snapped off by hand. Larger sucke...
Watch for the shallow roots to encircle, or girdle, the trunk of the tree. If this happens, they can cut off the flow of nutrients to the trunk, causing the tree to die. Remove any such roots. When a dogwood tree is planted can be just as important as how it is fertilized, watered...

Control of these diseases with the synthetic or biorational fungicides did not result in an increase in tree height or trunk diameter. While the biorational fungicides demonstrated sufficient efficacy for controlling powdery mildew on flowering dogwood in the landscape, they often failed...
