You have had a chance to watch your lawn evolve over the
years to where it is today. It may have bare spots or unwanted grassy or
broadleaf weeds that detract from its appearance. Unless you take some action I
can pretty well guarantee that the lawn will not evolve back to the lush green
uniform lawn that you once had at the start (assuming it was nice at one time).
First you want to identify the short comings and the causal
agents. Bare spots could be the result of pets, poor sprinkler coverage,
fertilizer burn, excessive shade, annual weed pressure, poor soils, etc. As the landscape matures and trees cast a more
shade the lawn may thin or nearly disappear. Weeds are easier to control when
you have properly identified them and know their life cycle. Crabgrass and
bermuda grass are not the same by any stretch.
Secondly, you will want to correct the things that you are
able to. I would definitely address the
sprinklers as they are a key element in having a thick, healthy lawn. Sprinklers
should be checked regularly throughout the season and adjusted as needed for
time and coverage. Poor soils could be amended or replaced. Tough perennial
weeds like dallisgrass and bermuda should be sprayed out a few times in August
and September to help eliminate them. There are no guarantees on totally
killing bermuda, but one can definitely hurt it badly.
The third step is to get the lawn thickened up with the
desirable grasses, but only after one has worked on the sprinklers and
perennial weeds. Preparation of the site is very important. Aeration and
dethatching assure that the seed will make good soil contact and increase your
chances of good germination. The area should be smooth and open up enough to
allow the seed to drop down to the soil below. In thin spots or areas where one
is essentially reestablishing a lawn, the use of a ¼ inch of humus to cover the
seed will help hold onto moisture and heat to establish the new seedlings. Finally,
the addition of a starter fertilizer high in phosphorus (the middle number on
the bag) will assist the seedlings to grow faster and with a healthier root
system going into the winter months.
That’s basically it. It is not rocket science, but it is
important not to cut corners. If you would like a free evaluation of your lawn
