one ************************** WEEDS ************************** Lawn weeds are usually the gardener's pet headache. Fortunately, most ordinary broad-leaved weeds can be controlled by one or more of the many weed control substances on the market. Not quite so easy to control are the grass weeds which are so similar to the desirable grasses that the chemicals which will eliminate the weeds can also damage the true grasses. two The best way to tackle these obstinate weeds is to catch them before they grow. Chemicals such as DCPA benefin and siduron will kill the weeds as they germinate. The herbicides should be applied evenly and regularly until the weed seeds have stopped germin- ating. Crabgrass, the gardener's favorite conversation piece, can also be controlled by catching the seeds as they germinate. If you are tackling a lawn where weeds are already well established, try one or two of the commercial threweed killers such as DSMA or MSMA, which you can find in most of the better garden stores. Some of the easiest to use weed eliminators are the so-called selective weed killers. These are mostly effe- ctive on the broad leaved weeds such as dandelion and clover. Be careful when using these selective weed killers. Don't spray on a windy day or even on a day with no breezes where there is the slightest chance that the spray can reach any of your prized plants or trees. four Although hardly recognized as a weed, moss can some- times cause bald spots on a lawn, usually in an area shaded by trees. These areas benefit by increasing aeration and loosening the soil. One last thought... Removing weeds from the lawn can be a satisfying task - get rid of the nuicances - but remember to seed and fertilize the cleaned areas when it is safe to do so. Nothing spoils the look of a lawn more than a series of brown or bald spots. END .....
