The 2007 season saw many weather related disease problems. The warm wet spring brought on many cases of Tar Spot, which affected primarily Norway Maples. It causes the leaves to have black "Tar" like spots on the surface. Severe cases can cause premature leaf drop. Wet conditions also favored the development of other diseases such as Rust and Scab, affecting ornamentals such as Hawthorns and Crabapples. Anthracnose on Maples and Ash, Needlecast or Spruce and Powdery Mildew on Lilacs were also prominent diseases last year. Cleanup of fallen leaves, fertilization, proper pruning and protective fungicide applications will help to combat these problems.
The amount of rainfall also has an affect on the mosquito population. Local out-breaks of Eastern Equine Encephalitis (EEE) in NH has raised concern and turned attention back to mosquito control. Natural areas such as tree holes, ditches, and swamps, as well as artificial areas like old tires and wading pools, allow water to pool and are perfect areas for mosquito development. Being aware of the potential problem areas in your landscape and eliminating standing water is the first step in managing these annoying pests.
