Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

Our trained applicator will notify you if your lawn shows signs of disease. He'll also advise you on the best treatment. Because lawn diseases are unpredictable and treatments are so variable, there is no guarantee of results. Application of lawn See similar questions...

Regular fertilization helps to maintain good lawns. In western Washington, apply N-P-K fertilizers in a 3-1-2 ratio (3 Nitrogen - 1 phosphorous - 2 potassium.) Examples of fertilizers in this ratio would be 21-7-14 or 15-5-10. Sulfur enhances color and helps control some lawn disease problems. See similar questions...

Limestone should be free of dust and dry prior to sealing. A low-pressure garden spray or similar device is ideal. Apply from the top of the stone and work down the wall. For areas close to windows and doors the sealant can be applied using a paint brush. Whilst reconstituted limestone, being a manufactured product, is denser it can still discolour and therefore it is advisable to seal the stone if the original colour is to be retained.

Horsetail control is difficult. The best management for it in lawn is constant mowing that keeps the plants down. This does leave the problem of the altered texture in the lawn where the horsetails come up, but short mowing will reduce that. In theory, if the plants are constantly mowed, they weaken. They are, however, long-lived and persistent no matter what measures are taken. There are no chemicals registered to control these weeds in a lawn. See similar questions...

For existing lawns, add a 1/2" thick topdressing of Spring Earth Soil Enhancer on the lawn. Each bag will cover a 30 square-foot area (6ft X 5ft). If you prefer a lighter topdressing of 1/4" thick, then each bag will cover approximately 60 square feet (6ft X 10ft). Apply Spring Earth in small piles and rake into lawn with a stiff lawn rake. Try both sides of the rake to see which side works best on your lawn. For lawn renovations and trouble spots, work in a 1" topdressing of Spring Earth. See similar questions...

Gophers are a very common rodent found in most areas of North America. They live exclusively underground where they can destroy plants by consuming the roots or pulling the whole plant down into their burrows. The most effective method of removing gophers is through trapping. Specialized traps are available at most hardware stores. Also available are poisoned baits, which are placed within the gopher burrow, though it is often difficult to find a bait attractive to your particular gopher. See similar questions...

First we must realize that a dry, dingy colored lawn as a result of drought conditions does not mean that the lawn is dying. Cool season lawn grasses simply go dormant during very stressful hot conditions. If a soil test has not been done in several years, this is a good place to start. By following the soil lab's recommendations in the spring you will know how much lime to add for optimal growing conditions. See similar questions...
