BLIGHT--CREEPING MYRTLE, PERIWINKLE, VINCA
Sudden death or thinning of vinca groundcovers usually
is caused by a canker disease that infects the stems, girdling the plants.
Vinca blight can be minimized by regular yearly mowings
in the spring, with the mower set on it's highest settings. Rake and compost
all clippings/cuttings. Fertilize and water to stimulate new growth.
