LAND AND LANDSCAPE CLEAN WATER PRACTICES

Your landscape is one part of a large system involved with watersheds. Watersheds are large areas that drain into common lakes, rivers or oceans. A rainstorm or excessive irrigation can wash pesticides, herbicides, and fertilizers from your landscape, onto streets, into the storm water system, and even the public water supply.

Fertilizer

Many homeowners use more fertilizers than may be necessary. Fertilizers contain nutrients that may contribute to low oxygen levels in the water.

Soil TestingFirst get your soil test done to see if your lawn or garden even need fertilizer or lime! Choose a fertilizer blend that provides the balance of nutrients recommended by the soil test results. Keep in mind that warm season grasses such as centipedegrass, bermudagrass, St. Augustinegrass or zoysiagrass are usually used in lawns in the midlands of South Carolina. These grasses generally require less fertilizer than others. When you shop, look for fertilizers that state that they are for southern lawns and apply them per label directions. You may also choose to use organic slow-release fertilizers such as well-composted manure, corn meal, cottonseed meal or other organic mixes. Use a mulching mower and leave grass clippings to decompose into your lawn.
Soil Testing Homeowners can get their soil sampled at Clemson Extension for $6 and this will tell you exactly what kind and how much fertilzer is needed for your yard and garden. This will save you valuable time and money as well as protect water quality.

Pesticides

Consumer pesticide products are readily available. But unless the product is formulated for the pest you have, and you apply them in the right way and at the right time, you could be wasting your money and causing more harm than good.

Pesticide and herbicide applicationThe first step is to identify your pest. Then choose the right pesticide for it, apply the minimum amount at the proper time, and follow all instructions and warnings on the label. Keep in mind that pesticides generally will kill most insects including beneficial ones. Unless specifically stated otherwise, should not be used near water bodies or storm water drains. You may find it simpler to contract with a landscape service which is licensed to apply pesticides. Often professional formulations are more effective than those available at retail outlets.

Herbicides

Many homeowners can't tolerate weeds in their lawns, but excess herbicide application may create intolerable conditions in our watershed!

Many common herbicides have been implicated in harmful effects in aquatic systems and particularly frogs and other amphibians and unless specifically stated otherwise, should not be used near water bodies or storm water drains. Commercial fertilizers may also contain herbicides as in "weed and feed" formulations. If you feel you need to use herbicides, just as with pesticides, identity the type of weeds you have, choose the right herbicide for them, apply the minimum amount at the proper time, and follow all instructions and warnings on the label. You may find it simpler to contract with a licensed landscape service.

Lawn Irrigations\

Irrigation

Make your watering or irrigation effective.

Most lawns in the midlands of South Carolina are warm season grasses such as centipedegrass, bermudagrass, St. Augustinegrass or zoysiagrass. Most of these grasses grow best with about 1 inch of water per week. In the case of no rain, apply 1/2 inch every three to five days. Too much water may wash fertilizer, herbicides, pesticides and pet waste into the storm water system. Too much water will also cause increased growth so you will have to mow more often, and it may allow diseases to develop in your lawn. You can even let your lawn go dormant during drought saving water and money. If you have an irrigation system, it should be tuned to provide the correct amount and flow of water on the proper schedule.

Xeriscape

Alternative Landscapes

A turfgrass lawn is not your only option!

You've probably heard 'If you can't grow grass, turn it into a natural area.' You can do that with areas or your entire lawn by utilizing low-maintenance ground cover plants, natural mulch materials, native plant materials, and other landscaping techniques. You could also explore a xeriscape which simply means a sustainable, drought-resistant landscape that does not require additional water.
