Common Pests
-
Minimize pest populations on fruit by removing infected berries; prune lower branches to improve air circulation; rarely requires treatment on ornamental trees
-
Prune heavily infested branches; spray horticultural oil in dormant season; monitor in summer and treat with insecticidal soap if populations increase
-
Remove affected leaves and small branches; apply neem oil or spinosad if infestation is severe; usually self-limiting
-
Increase humidity and water spray on foliage; apply horticultural oil or neem oil; avoid over-fertilizing which promotes tender growth

Fun Facts
- 🌱 Kousa dogwood is more resistant to dogwood anthracnose (a serious fungal disease affecting native flowering dogwoods) than American dogwood species, making it an excellent disease-resistant alternative for gardens.
- 🌱 The tree's name 'kousa' comes from its Japanese common name; it is also known as Japanese dogwood, Chinese dogwood, or Korean dogwood depending on the specific origin of cultivars.
- 🌱 Unlike the spring-flowering American dogwood (Cornus florida), kousa dogwood flowers slightly later in the season (late May to June), allowing gardeners to extend their dogwood blooming period by planting both species.
