Mosses, like most lawn weeds, primarily take advantage of bare areas but do not kill out existing grass as some people believe.  Bare areas in lawn can be a result from several causes.  Unsuitable grass varieties, poor drainage, drought, soil compaction, excessive shade, thatch accumulation, poor fertility, diseases, improper mowing and other cultural practices are common reasons for turf failure leading to moss or other weed problems.  Improving these factors to encourage thick, healthy grass is the key to long-term prevention.

Moss can be killed with products containing ferrous sulfate, ferrous ammonium sulfate, including Moss-Out, Moss-Kill, Rid-Moss, and a variety of Lawn Fertilizers with Moss Control; or moss & algae killing soaps such as Safer’s.  None of these materials pose serious threats to the environment; in fact iron and sulfur are essential nutrients for grasses and tend to improve their color.  Although these products will kill existing moss, unless the underlying conditions are changed, moss or other weeds are likely to reappear.

Poorly adapted varieties of grass may fail due to cool temperatures, inadequate drainage, or prevalent diseases.  Poor drainage and soil compaction can cause roots to suffocate or be subject to disease.  Thatch and soil compaction can impede water movement to grass roots, leading to drought stress.

Raising the soil PH (or sweetening) with agricultural or dolomite lime can improve availability of nutrients and supply calcium and thus helping the turf grow better, but will not kill moss directly.  The following steps will generally control existing moss and discourage it in the future:

  1. Use a moss control product to kill existing moss in late winter or early spring.
  2. De-thatch or rake out dead moss, or skip step (1) and de-thatch or rake with more vigor.
  3. Fertilize and lime your lawn.  Fertilize with a 3-1-2 ratio mix.  (We recommend using  21-7-14 to fertilize and Calpril lime to sweeten your soil.)
  4. Over-seed bare areas with a good lawn seed mix.
  5. Top-dress seeds with about 1/4 inch of loose weed-free soil, potting mix, or sand. (Or rake seed into the soil.)
  6. Keep moist until seedlings are established.
  7. Lime your lawn in the spring and fall to avoid future moss problems.

The following practices may help specific situations:

Did you Know . . . ? ? ?     BEE Fun Facts

* A honeybee has to travel over 55,000 miles and visits approximately 2 million flowers to

make 1  pound of honey.

*  A honeybee can fly approximately 15 miles per hour.

*  A honeybee will flap its wings about 11,400 times per minute creating the “buzz” you hear.

*  A typical beehive makes more than 400 pounds of honey per year.

*  Honey is the ONLY food that includes all the substances necessary to sustain life, including                 water.

*  Honeybees are responsible for approx.  80% of all fruit, vegetable and seed crops in the U.S.
