Cedar rust infection spot Warm weather in early spring means scab, cedar apple rust and powdery mildew diseases are upon the new leaves as they start to emerge.

Some grafted and budded shrubs and trees develop a bad habit to sending up shoots (suckering) from its rootsystem. This creates an untidy appearance around the base of shrubs and trees. Far worse, the root suckers may compete for domination over the cultivar graft. They may rob photosynthate, water and nutrients from the grafted plant. Eventually, the grafted portion may die. Gardeners select grafted plants for a number […]
