How do I keep my lawn green during the hot summer months?
Rate This FAQ
Summer heat stresses lawns. With proper watering and attention, however, you can keep your grass green and healthy. Consider these tips.
* Measure as you water. Lawns require as much as one-third inch of water per day, or 2.5 inches per week in mid-summer. To measure water application and help determine length of watering time, place a 6-inch deep, or more, straight-sided can in several locations around the lawn. Run sprinklers, then measure the water in each can and average the results. Also keep track of how long it takes to fill the can with the right amount of water so you can determine length of watering time.
* Be aware of water penetration. Water should penetrate about 8-10 inches per application. To determine depth of water penetration, push a rod or screwdriver into the turf and measure how far it goes in. Water deeply and as infrequently as possible. Too much water causes iron chlorosis or yellowing in turf, trees and shrubs. It also carries away fertilizer.
* Know your soil type. This will help determine frequency in watering. In mid-summer, sandy soils need to be watered about every two days. Loamy type soils need water every three to four days, and clay soils need water every four to six days.
* Watch your mowing height. This is an important factor in minimizing lawn stress. Keep the lawnmower blade adjusted at 2.5 to 3 inches. This will reduce water loss to the grass. It will also help keep turf and roots thick, which will reduce weeds. Keep the mower blade sharp to prevent lost moisture through ragged grass blade tips.
* Fertilize your lawn every four to six weeks throughout the growing season. A properly fertilized lawn needs one pound of nitrogen applied per 1,000 square feet.

- Yesterday I applied "Scotts Turf Builder Plus 2 Weed Control" to my lawn. Unfortunately, I had the drop spreader set incorrectly. As a result I later discovered that I had accidently applied 4-5 times as much fertizer as specified on the bag. Will this damage the lawn? Is there anything I can do to prevent damage?

- I've neglected to do my "last mow" up to this point. We've already had several nights of light frost. My grass is long but I worry about causing even more damage by mowing at this late juncture, mid-November. Are there any risks to mowing grass after the first few frosts?
- I have many large 20-25 feet scrub oak trees on my property. I would like to thin and prune them from the tops in order for them to look like the lower scrub oak I have seen in the area, about 10-15 feet. How low can I cut them from their tops without injuring them and what is the best time of year to do so?

- I am an architect, working with a client who wants to hydroseed a 2.5 acre parcel for use as a softball field. The area is currently planted in alfalfa. There will be some regrading (both cut and fill) of the field that will be required. The client would still like to hydroseed this year, likely near the end of September. Do we need to call for the alfalfa to be treated with a herbicide? If so, what is the process, and what herbicide should be used? Is there a waiting period between application of the herbicide and the hydroseeding? Must the herbicide be applied to the above-grade plants, or can the site first be cleared, then the herbicide applied to the gound and roots?
