Summer
days mean lots of sun, fun and hopefully a yard that will hold up to
the weather as well as outdoor gatherings. If you are like most of us,
you want to know how to have a nice lawn all year, and especially
during the summer when you spend more time there. The following are
some of my best tips for keeping your lawn healthy and looking great
throughout the summer months.
Raise the mowing height a little bit.
Taking the mowing height up a notch will do wonders for your lawn
during the summer. First, it will make scalping less likely. You never
want to cut more than one-third the height of your lawn in a single
mowing. If you don’t scalp your lawn, it will make weed encroachment
more difficult. The greater amount of leaf blade showing will keep your
yard appearing greener while the roots have a chance to grow deeper,
which helps the lawn during times of drought.
Manage high traffic areas.
Before mid-summer, you know where these are. If the grass is being worn
down on the walkway off the patio or other high-traffic areas, you can
do a couple of things. First, give these areas a little extra shot of
fertilizer (this can be the extra 0.5 lb. of urea or just simply go
over the area a second time with your regular fertilizer application).
The grass blades are constantly being worn and are trying to
regenerate, so a bit more nitrogen will help them recover. This is
exactly what the landscape pros do in high traffic areas of sports
stadiums. Next, consider topdressing the areas with crumb rubber from
used tires. Your objective is to build up a ½ inch layer (this equates
to about 1.0 lb. / sq. ft.). The idea is to have a mat that will absorb
the traffic (instead of the soil) but still be porous enough to allow
the lawn to grow and water to move through it. The product can be found
in 50 lb bags. Make sure you buy the size particles that range from
0.5-3.0 mm in diameter.
For summer broadleaf weed control,
use products containing carfentrozone. Summer broadleaf weeds are tough
to kill with the same herbicides that easily control these weeds during
spring and fall. The later into summer, the more difficult the task.
Weed control products containing carfentrozone will burn the top-growth
of the broadleaf weeds like oxalis, purslane and speedwell with no
adverse effect on grass. Similarly, if you have crabgrass, buy a
product containing quinclorac. You will find it under the trade name
Drive, and it is very effective on mature crabgrass plants throughout
the growing season. In some states, you can now purchase quinclorac
already mixed in with regular 3-way herbicides for broadleaf weeds
(both Scotts and Bayer sell these products). This is an effective
herbicide combination that will kill the vast majority of weeds in your
lawn.
Green up the lawn for special occasions.
One of the great tricks to green up a lawn in the summer is a light
dose of urea. We are talking about 0.5 lb N/1000 sq. feet, or roughly
2.0 lbs of product (46-0-0). Urea is inexpensive and will provide a
“green up” in 2-3 days, assuming it receives adequate water from rain
or a sprinkler. This product can be used in between your regular
fertilizer applications to help “revive” your lawn following heavy
outdoor entertainment or sporting activities, a pest invasion or simply
lots of rain. Bear in mind that there are a couple of downsides: you
should not go above this recommended application rate, and understand
that the product’s effects will only last a short time (2-3 weeks).
Applying too much urea can burn your lawn, negating all your good
intentions.
Control beetle grubs now.
Finally, if you live in areas where beetle grubs like European Chafer
or Japanese Beetle could be invading your summer lawn, one of the best
precautions you can take is to apply Imidacloprid (Merit or Grub-Ex)
during the first three weeks of July. This will control the grubs just
as they hatch and provide you control and peace of mind until next
summer. This insecticide is also extremely kind to the majority of the
beneficial insects in your lawn.
So this summer don’t dread the
wear on your lawn - embrace it with a positive attitude with these
tips. You’ll make your lawn and the neighbors green with envy.
