An organic lawn is quite different from lawns that use chemicals. To kill weeds and prevent the need for excessive weeding, the care this type of lawn requires is quite different as well.
It is actually much easier to care for the organic lawn than to have to run out and purchase all those chemicals and expensive products to perform your lawn maintenance chores.Although getting started with an organic lawn may take a little extra care on the part of landscapers at first.
One key to maintaining a lush organic lawn is to mow high. The logic behind this is that both grass and weeds fight for sunshine because sunshine is their food source. When weeds are buried in the shade of healthy, slightly taller grass, they can not reach this crucial life-source and only the extremely opportunistic weeds will survive. Most common weeds, like crab grass, are not that strong and will simply be crowded out by healthy, organically grown turf grass. When you cut your grass too short the blades of grass become stressed in order to produce sufficient chlorophyll in the photosynthesis process. Allow the grass blades to have enough length to turn the sunshine into nutritious sugars and it will brow into a thick, lush carpet of turf.
Another good piece of lawn mowing advice, when the organic lawn is mown it actually helps the grass to leave the clippings on the turf if you are using a mulching lawn mower. These clippings turn into organic matter and actually provide nutritious fertilizer for the growing grass. If you find the clippings become clumps, you should clip a little more frequently. A lawn trim is much better and less work than a major cut.
Water your organic lawn just as it begins to curl but before any patches begin to turn brown. To check whether you really need to water, stick a shovel about six inches into the soil. With the sun on your left or right side, push the handle of the shovel forward. If you can see any moisture in the soil, it is not time to water yet. If, however, it is dry, your organic lawn will really appreciate a good soaking. If you can not insert a shovel into your soil six inches, you have poor soil that needs aerating and amending with lots of organic matter.
When you do water the organic lawn, it is important to really soak it rather than simply spraying it lightly with water. You want the water to seep deep into the soil. If you stand and spray your lawn with a hose for a few minutes, you are simply watering the weeds, not the turf! It is also important not to overwater the lawn. If there are puddles in the organic lawn after you water, then you have watered for too long. This leaves room for lawn diseases.
Organic lawns require lots of nitrogen. Plants like clover and black medic are capable of getting nitrogen from the air because they are legumes. If you see these plants appearing in your lawn, you do not have enough nitrogen in the ground soil. Find a good organic fertilizer or compost the lawn from your organic compost pile. It is a good idea to fertilize the turf in the spring and last summer even if it does not have these plants as indicators of a problem. Fertilizer acts as organic pesticides to prevent their appearance.
By following these tips to caring for an organic lawn you will solve almost all your weed problems. The few weed problems that may crop up can be removed by hand or you can contact your local County Extension service and request specific advice for the particular weed that is invading your organic lawn.
