Comments about Howard/Carroll Co. test scores:

Asian tiger mosquitoes DO NOTrespond well to traditional control methods.
Physostegia virginiana, obedient plant, is a native plant.
As far as I can tell, heavenly bamboo, Nandina domestica, although exotic, is not invasive in MD. It is in Florida, though. Many species of bamboo are invasive here in MD.
Silver maple is native to MD; Amur maple is native to China.
Crepemyrtle is also native to China & Korea.
Boxwood is native to Japan, southern Europe, Northern Africa, depending on species.
According to Dr. Felton, 50% of homeowners do not fertilize their lawns.
The type of fertilizer most potentially harmful to the bay is a water soluble type because it has a great potential to move off target and pollute ground or surface water.
Underground storage tanks CAN be tested for leaks.
The U of MD recommended rate of nitrogen fertilizer is 1 pound of nitrogen per 1,000 square feet of turf per application
Because of their higher phosphorous rates, 10-6-4 and 5-10-5 are not the better fertilizer for an established lawn. A better one would be a low to no phosphate formulation.
Some of us still need to review the WIN calculation on our cherry-pink half sheet.
Remember the calculation to determine WIN:
20 - 10 - 10
Guaranteed Analysis
Total Nitrogen                20% (by weight)
8% Water Insoluble Nitrogen (by weight)
Available Phosphate        10% (by weight)
Water soluble Potash      10% (by weight)
To determine what % of the total N is WIN, divide the percent of water insoluble nitrogen (WIN) by the percent of total nitrogen and multiply by 100.
8 ÷ 20 X 100 = 40%
