The Q&A Archives: lawn

Question: I water the lawn every 2 days for about 10 min. I am getting brown spots all over the lawn. My lawn is small and onle in front of my house. Am I watering to much or is there a other problem? How many times should I fertlize the lawn?

Answer: Most grass types will get by on one-inch of water per week. The roots will deeply penetrate the soil in search of moisture, so be sure to water thoroughly but infrequently. Depending upon your soil type you should be able to keep your lawn looking its best by watering only once or twice a week during the summer months. To help you figure out how much water you're applying, put two or three empty tuna or cat food cans on the lawn and turn your sprinkler on. Time for 15 minutes and then check the level of water in the cans. When you've applied a full inch of water, write the time down. That's how long you'll have to run your sprinkler to give your lawn its full one inch of water. If you have sandy soil, apply one-half inch of water each time you water, and plan to water every 3 days. If your soil has more clay than sand, it will retain the moisture longer and you won't have to water as often.

As for feeding your lawn, the best schedule is to apply a 3-1-2 ratio of NPK four times a year (April, June, September and November). Home Depot generally has the right formula on sale at the right time of year for application so watch the sale ads.

Hope this helps clear the confusion!
