Learning to water your lawn properly is very important to maintaining a healthy condition. Most issues are due to poor watering practices.
Turf grass will let you know when it is dry by changing color to a slightly blue color. If examined closely, you will also notice that the turf is limp. If you step on the dehydrated turf it will not spring back as well as hydrated turf.
Too much water can deprive roots of oxygen. During the warm, humid summer months, too much water can increase the chances of diseases. If you are concerned that you may be applying too much water, reduce watering until you begin to see discrete signs of wilt, then increase you time by a small amount.
Mower blades must be maintained in sharp condition to keep your lawn looking its best! Dull blades do not cut evenly, so this will result in damaged grass and a brown cast over the lawn. A sharp blade will cut more evenly and leave only a minor opening that heals quickly. Be sure to not cut your grass too short, as this will cause damage.
Most sod varieties require weekly mowing during the growing season. Make sure your mower is clean of weeds prior to cutting your lawn because they can be transferred from one lawn to another.
A good general rule is to fertilize twice a year, in the spring and fall. Fertilize with an all purpose fertilizer to promote root growth. General purpose fertilizers have a balanced blend of nitrogen, phosphorous, and potassium.
