Our native dogwoods are beautiful trees, but since late in the 1970's they have been under attack from the fungal disease anthracnose. The trees leaf out and bloom in April, and then the fungus attacks and the trees begin to defoliate. There is no real cure or treatment.
We had a number of young native dogwoods on the property when we had our house built here, but slowly they have been killed off and have had to be taken down. We appreciate native species, and especially the lovely dogwoods, so we do not remove them until they actually die. We just rake up the mess and dispose of the leaves.
Where we have lost some trees important to the landscape, we have replaced them with Korean dogwoods (Cornus kousa), which are resistant to the disease. Below you see a native Pacific and a Korean dogwood side by side.
The Korean dogwoods bloom in May/June and are in full bloom now.
We got a heavy set of blooms this year on our two kousas.
