|Recently purchased new home, lawn is 90% weeds. e have a fairly small lot. We are planning to spray to kill weeds, what is our next step? We have a sprinkler system, do we bring in dirt and spread 3|
|You can selectively kill the weeds or you can purchase a weed and feed product such as Turf Builder Plus 2. Combination products will go after the weeds and feed your lawn at the same time. I'd take care of the weeds and feed the lawn before raking and reseeding bare areas. When the lawn is healthy it might spread to fill in those bare areas. If not, you can overseed about 30 days after using the weed and feed (check the package label for waiting periods before reseeding). If you put your lawn on a regular watering, feeding and mowing schedule it will green up and grow lush and thick.
Turfgrass needs to be watered once or twice a week, depending upon weather. Deep soakings are preferable to daily sprinklings. Plan on applying one inch of water per week to your lawn. You can measure how much water your sprinklers put out by setting some empty cat food or tuna cans on the lawn and running the sprinklers. Start with running them for 15 mintues and then checking to see how much water has collected in the can. Your goal is a half inch if you water twice a week or one inch if you water once a week. The time it takes to deliver the proper amount of water is the length of time you should run your sprinklers. If water begins to run off the lawn before you get the required amount of water in the cans, plan on running for a while, turning the water off to allow it to soak in, then turning the water back on until the sprinklers have run for the correct amount of time. Plan on feeding your lawn in April, June, September and late November or early December. Use turf builder with weed control if you still have broadleaf weeds in your lawn in mid-summer. Mow as often as necessary to keep your lawn at 1 1/2 to 2 inches in height. The general rule of thumb is to remove no more than one third of the grass blade when you mow. So, mow when it is 3 inches high and take off no more than one inch of grass. Best wishes with your lawn!
