[header] How to feed a warm season lawn [title] Take a soil sample of your lawn. [step] A soil sample will give you an evaluation of the nutrients and determine what amendments or fertilizers will work best for your lawn. To take a sample, use a gardening spade and dig 5 holes that are 6-8 inches (15-20 cm) deep in several areas of your lawn. <sep> (A) [substeps] Avoid digging any deeper than the hole you are taking your soil sample from. Digging 4 holes too deep, or too small, could cut off the nutrients your soil provides for its root system, which could cause your grass to die. (B) Put the soil that you unearthed in a clear container and send it to your nearest cooperative extension. [substeps] You can take samples of your soil annually to keep up with the changes in nutrient content. (C) If the holes are shallow, use a flashlight or electronic device to locate the depth on the soil. [substeps] You can purchase soil samples at most major gardening and home improvement stores. (D) [substeps] Be careful, as you could trip on a garden hose and injure yourself. You can disinfect the soil during use by using two or three levels of bleach to dissolve it, then repump if necessary.
