At Good Nature
we classify lawn problems into two categories: Actual Problems and
Symptoms of Actual Problems.
Some common actual problems are:
Excessive
Thatch Layer
Incorrect Grass Types
Poor Soil
Some common symptoms
are:
Diseases (Dollar Spot, Red Thread, Brown Patch, Pythium, etc.)
Insects (Grubs, Chinch Bugs, Sod Webworm etc.)
Weeds (Clover, Crabgrass,
Dandelions, etc.)
Diseases
Lawn diseases result in brown sections
of turf. When grass is unhealthy, it will get sick, just the way
humans do when we’re unhealthy. Chemically fertilized turf
is highly susceptible to disease outbreak because:
1. The soil life
is virtually non-existent so there are no organisms available to
battle with the disease organism.
2. The turf typically has a sizable
Thatch layer which invites diseases
3. The turf is typically shallowly
rooted which will make it less able to fight disease.
Other factors
can contribute to disease problems:
Incorrect watering (Watering
heavily in the evening or watering the same area more than 2x per
week)
Insects
After 2 or three years on a Good Nature lawn program
your grass will rarely have an insect problem. Insects can be prevented
by:
1.Maintaining a healthy soil environment (using organic fertilizers)
2.Aerating once per season
3.Overseeding with insect resistant varieties
of grass
Grubs are one of the most common problems in Ohio lawns.
If you are worried about grubs or would like to sign up for our natural
grub control service, please contact the office via phone or email

Weeds
The best defense against weeds
is a healthy stand of turf, which will crowd out and compete with
the weeds. Our fertilizer program combined with Aeration and overseeding
(if necessary) will build a healthy thick stand of turf to crowd
out weeds. Weeds grow in conditions where grass doesn’t thrive,
we’ll take care of the weeds you have, and make sure you’re
grass starts thriving.
Excessive Thatch Layer
Thatch is the layer
of dead roots and stems between your green grass and the soil. A
small amount of thatch (1/4”) is healthy, but many of the lawns
in Northeastern Ohio have thatch layers over ½” thick.
Why is too Much Thatch Bad?
Excessive thatch prevents water and nutrients
from reaching the soil. à Turns Brown in Summer! Excessive
thatch provides the optimal conditions for disease problems à Brown
Spots! Excessive thatch provides a great home for insects and grubs. à Brown
Spots!
Why does thatch accumulate?
Leaving your clippings on the
lawn does NOT contribute to Thatch accumulation! If anything, leaving
a small amount of clippings each time you mow will help to encourage
beneficial soil life and reduce thatch. Thatch accumulates for
a variety of reasons, not the least of which is the type of grass.
Kentucky bluegrass, for example, tends to produce a lot of thatch,
whereas Turf Type Tall Fescue tends not to. In a healthy organic
lawn, no matter what type of grass you have, thatch will be minimized
by the abundance of beneficial soil organisms eating it and converting
it into plant food. In a chemically fertilized lawn, the microorganisms
are less abundant and very often can’t decompose the thatch
as quickly as its created.
What Should we Do about
our Thatch Problem?
There are two things you can do to help reduce
your thatch layer and get your lawn back on track.
1. Core Aerate
2. Fertilizes Organically
Core aeration penetrates through the
thatch layer into the soil, bringing up cores to the surface. If
you have healthy soil, these cores will contain billions of thatch
eating microorganisms who will go to work on your thatch as they
work their way back down into the soil. If you don’t have
healthy soil, the aeration will at least eliminate –temporarily-
the immediate insect and disease threat by allowing water and nutrients
to reach your grasses root system.
Organic Fertilization will help
stimulate microorganism populations and will help create the healthy
soil you need to start digesting thatch.
What about De-Thatching?
University studies have shown that de-thatching is a waste of time,
money, and can even do more harm than good in most situations.
De-thatching only removes the top layer of thatch and stresses
the grass, providing a great opportunity for weed invasion.
There
are only two situations when a power rake / de-thatcher would be
appropriate to use on your lawn.
1. If you are using it to lightly
rake off matted leaves and winter dubree.
2. If you are using it
to prepare a lawn for seeding – In
which case you’ll have to use it heavily so that you almost
remove all the existing grass.
Incorrect or older Grass Types
Many
lawns contain grasses which are not suitable for their locations.
Misplaced Shade Grass
Fine Fescue thrives in the shade, but if
for some reason the shade is removed, it will struggle during any
warm weather. It would be a good idea to at least aerate and overseed
these areas to get some new grass started.
Bentgrass
Another common
problem in Northeastern Ohio lawns is Creeping Bentgrass. Bentgrass
is a lighter green color than Bluegrass or Ryegrass and spreads
rapidly. It usually starts as a small patch and gradually increases
in size until it takes over much of the lawn. Bentgrass is difficult
to maintain because it is susceptible to so many disease problems
and doesn’t
do well without constant irrigation. Many times you’ll see
brown patches in your lawn, and on closer inspection notice that
they are all the bentgrass areas turning brown. What’s the
solution? This is a tough one. The only solution we have is to
kill off the bentgrass with soil solarization or roundup and then
reseed the areas. In some cases it may be worth it to replace the
entire lawn.
Warm Season Grasses
Nimblewill and other warm season
grasses can invade our turf and blend in well until the weather
gets cold – then
they immediately turn brown. Aside from killing the lawn and starting
from scratch, there isn’t really much we can do about these
grasses.
Poor Soil
Many new developments have grass planted in
subsoil. Grass planted in these conditions will be vulnerable to
drought stress, insects, diseases, and will have a more difficult
time crowding out weeds.
What can I do with my poor soil?
As strange
as it sounds adding topsoil isn’t really the answer. Most
topsoil sold isn’t
very high quality and relative to its cost, isn’t worth the
effort. Your best bet is to apply an Organic Compost Topdressing
to get off to a good start. Topdressing adds a large amount of
beneficial soil organisms and helps to instantly energize the soil.
You’re
lawn will be the envy of your neighbors. After topdressing, our
fertilizers will continue to build up the soil organic matter and
microbe population. If you’d like to skip the topdressing,
our fertilizers will have the same effect, but take a little longer
to build up the organic matter in the soil. |
