Kousa dogwood tree

Asked March 11, 2015, 11:49 AM EDT

We are planting a tree. Hopefully, we will plant a Kousa dogwood. In the paper they mentioned that dogwoods are struggling against powdery mildew and anthracnose. Does this affect the Kousa dogwood? If, so, any recommendation for something similar?

Kousa dogwood, or Cornus kousa, is much more resistant to both dogwood anthracnose and powdery mildew. However, not all cultivars show good resistance. Some kousa dogwood cultivars with intermediate disease resistance include ‘Milky Way Select,’ ‘Gay Head,’ ‘Julian,’ ‘Temple Jewel,’ and ‘Elizabeth Lustgarten.’

Several kousa dogwood cultivars are also resistant to powdery mildew. In recent field trials, the kousa dogwood cultivars ‘Milky Way,’ ‘Milky Way Select,’ and ‘National’ have remained nearly free of disease symptoms.

In addition, the cultivars ’Gay Head,’ ‘Julian,’ ‘Temple Jewel,’ ‘Big Apple,’ ‘Greensleeves,’ and ‘China Girl’ along with the recently released hybrid dogwoods ‘Stellar Pink,’ ‘Star Dust,’ ‘Galaxy,’ ‘Aurora,’ and ‘Constellation’ have also been shown to have good disease resistance.

Good site choice and soil preparation are key to the establishment of a dogwood tree as well.
