Please choose the correct ending to complete the given sentence: Home and Garden: [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.

Ending1: [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. Ending2: 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. Ending3: 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. Ending4: [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.
