Lawn not looking right, have a yellow spot? What’s wrong and what can you do?
Always check watering first with any lawn problem, this is a very common culprit to lawns not looking right in the heat of the summer. A good check for lawn moisture is to stick a regular length screwdriver into the soil. If you can very easily insert it up to the handle your lawn is probably getting sufficient water. You can also overturn a piece of sod with a shovel and check the soil underneath for moisture and its depth, as grass roots can be several inches deep. Every watering should penetrate the turf and travel into the soil 6-8 inches. You can measure water and sprinkler output by following the tips in the Lawn Watering section of our website. If the spot has any straight edges it is likely a watering problem.
Very seldom are sprinkler systems set up so they water adequately and evenly in all locations throughout your landscape. If you have a dry spot use the measuring tips in the Lawn Watering section of our website to measure the output in that area. You can try installing a higher gallon per minute head or nozzle in that area, adjusting the spray pattern, or upping the minutes on your control box for that station. You can also just spot water the old fashioned way with a hose and sprinkler to avoid running all your sprinklers to fix one small spot. If your lawn is starting to yellow everywhere, it could be a sign of either not enough water, to much water, or possibly a lack of nutrients, it may be time to fertilize.
