During the spring we receive quite a few calls from people who ask, "How much do you charge for core aeration in the spring?" And our short answer is nothing!
As a general rule of thumb, spring is not the best time to aerate and seed your your St. Louis lawn and this is why.
Spring is the time to put down crabgrass pre-emergents to prevent weeds from germinating.
The basic way the pre-emergents work is by forming a barrier on the soil that prevents weeds from popping up through the soil. When you seed your turf, you will likely want to aerate the lawn first. Aerating will break this barrier, thereby eliminating the effectiveness of the application.
Even if you are not aerating prior to overseeding your turf, the grass seedlings growth will be inhibited from the pre-emergent application.
Do NOT skip the crabgrass pre-emergents in the spring months. In fact, it is so important, that Dowco clients will receive 2 applications of pre-emergents before summer if they are on our fertilization and weed control program.
If you skip this application, your summer will be spent trying to rid weeds in your turf.
The seedlings will not be ready before the summer heat.
Fescue and Bluegrass are the two primary types of grass seed planted in St. Louis. They are both cool season grasses and they do best in the temperatures and climate that fall has to offer.
When planted in the spring, the grass seed does not have enough time to mature before the intense St. Louis summer heat wave.
In the fall there is still plenty of sunshine, rain or dew, the ground stays warm, and the temperatures get cooler. There is also less heat and threat of disease that may hinder the germination of new grass seed. While immediate results may not be seen in the fall, they will be seen in the spring in the form of a thick, lush turf.
Many people aim to put down grass seed in the fall, around Labor Day. Until then, fertilize the grass that you do have and be patient. Once you get through this year with a great fertilization and weed control plan for your St. Louis lawn and fall aeration and seeding you will reap an 80% improvement by spring of next year.
