Summer is here and you can start enjoying the lawn you’ve worked so diligently to perfect. But don’t stop now! In addition to fertilizing, proper mowing can strengthen your lawn’s resilience against pests and weeds. Good mowing requires vigilance and an understanding of your grass type.
1/3 Rule- Continue to mow as necessary, always following the 1/3 rule.
How Tall? Allowing the grass to stay tall keeps weed seeds from germinating. Keeping the lawn tall throughout the summer will keep the surface of the soil from drying out and reduce the need for watering. Cool –season grasses should grow 2 ½ to 3 inches tall and Warm-season grasses should be kept 1 to 2 inches tall.
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. The pieces break down quickly and reduce the amount of fertilizer you have to use by as much as 25%. Research has proven that the clippings don't cause thatch to build up.
Disease- Look for signs of insects and diseases in the lawn.
Fertilize with an application of Milorganite around the 4th of July (cool season grasses).
Weeds- Remove weeds by hand be sure to 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 Eco-frienldy weed control tips view our video here.
Water deeply and infrequently in the early morning hours as needed. Turf requires 1” of water per week total. Or, allow turf to go dormant .
