As your lawn endures the trials of job this summer – drought, pestilence and disease – you must hold to the hope that there is a lush, green turf on the other side of this summer. Has your spring turf been reduced to an arid, brown toasty color? If not, you might want to submit your water bills for federal disaster relief. Dry, scorching heat is the perfect scenario for crabgrass to flourish and bluegrass to perish. What’s needed, of course, is a good, deep penetrating rain.
The large Japanese beetle population will mean a heavier than normal population of grubs. Knowledge is of course your best defense. Here are a couple of suggestion for coaxing your sod through the trials of summer…
Feeding: Your lawn’s nitrogen needs are at their highest in late summer. Avoid fertilizing when temps are about 85 degrees. Supplement this late summer feed (high in nitrogen) with a fall fertilizer that will concentrate on developing the root system. This will build a turf more resistant to drought and pest damage. This might be your most beneficial feeding. You can supply a fall food right into November in most areas.
Pest Control: In late summer and early fall the grub cycle begins as the larvae pupate into the common white lawn grub. At this stage of their development, these grubs are the most vulnerable. Treat infested areas with milky spore, an organic alternative to harsh chemicals. For more information visit the NOFA website.
Watering: A good rule of thumb is to water in the early morning hours. Try to provide at least 1 to 1.5 inches of water through rainfall or irrigation. A deep watering once a week is more beneficial than a series of shallow watering.
Seeding: To repair damage caused by drought, pests and disease, plan on a fall seeding program. Match the grass seed varieties to the conditions. For example, if you have a rocky, sandy soil that doesn’t hold moisture well, use a drought resistant lawn mixture featuring turf-type tall fescues (TTTF). Unlike ryegrass that spread by shallow rhizomes, TTTF have long individual tap roots. They are tough, durable and make a long wearing attractive turf. Heavy clay soils might do better with a bluegrass and ryegrass mixture. Fall is an optimum time for seeding. The warm weather speeds germination while the autumn night temps start to drop. Remember to keep the seed moist until established. That might require 2-3 mistings during our “Indian Summers”. The attention you pay to your lawn now will pay big dividends in the fall, the following spring and for years to come.
