Summer Lawn Care

Summer is here and you can start enjoying your lawn; just remember to mow tall, mow often, and recycle grass clippings. In addition to proper mowing, fertilizing can strengthen your lawn’s resilience against pests and weeds.

Mow Tall

Tall grass keeps the surface of the soil from drying out, reduce the need for watering, and prevents weed seeds from germinating. Tall grass also encourages deeper root growth. Depending on your region and type of grass will determine your mowing height.

Recycle Clippings

Grass clippings are valuable organic matter, full of nitrogen and other nutrients. As long as you mow often and remove no more than 1/3 of the grass blade, you can just leave clippings on the lawn.


Apply an application of Milorganite around the 4th of July (northern grasses). A summer application of Milorganite will continue to give your lawn the nutrients it needs. Milorganite will not burn your lawn even in the hottest temperatures and driest conditions.


Remove weeds by hand and get the entire plant and root if possible. If weeds have taken over, spot spray with a post emergent herbicide (avoid using during hot weather). For more Eco-friendly weed control tips view our video.


Water deeply and infrequently in the early morning hours as needed. Your lawn requires 1” of water per week total. Or, allow your lawn to go dormant.


Look for signs of insects, pests, and diseases in the lawn.
