Dogwood Anthracnose

Anthracnose is hitting landscape and forest trees hard in eastern TN.  There are ways to protect trees at the early stage of infection; first visible as dry-dead spots on leaves or petals which later moves into the woody tissues.  Better Nature can help save and protect these iconic beauties through a comprehensive approach involving treating the disease in the plant and improving the soils the trees live in.  Wood weakened by the anthracnose is more accessible to the dogwood borer.  That's why a comprehensive treatment is required and why this is more than an unsightly disease.

Emerald Ash Borer and Woolly Adelgid

EAB - Using a preventative, broad spectrum, systemic insecticide, trees can be protected however, treatment should start as soon as you have confirmed infestation within 15 miles of your trees.  Treatments need to be repeated every 2 to 3 years.

The Woolly Adelgid - treatments are pro-active and after infection can save your hemlocks; only one treatment is needed.

Please, see the blog page for more details about this disease hitting us hard.  It cannot be cured but the plants can be cared for (sterile pruning, soil cultivation, and biofertilization) to increase their immunity and slow the spread of the disease.  The best solution, in my opinion is to remove them and replace with resistant plants e.g. Eastern Red Cedar.

Soils are Fundamental

Soils in eastern TN can be diverse.  Most soils in new developments and elsewhere, are heavy clays.  If the pH of those soils is too high (basic/alkaline) then addition of nutrients doesn't work.  Changing the pH of the soil is critical to making nutrients available to the plant and also critical to a plant's immune system.  A soil analysis is inexpensive but can help reduce the long-term costs of living with bad soil - the costs to your bank account and to plant and tree vigor!
