When should I see results from my lawn aeration treatment?

If you are watering and mowing correctly, as a rule of thumb, during the growing season you should see results in 2 weeks. For weed treatments (and depending on the specific weed type) you should see “curling & wilting” in about a week. It may take up to 3 weeks for weeds to die, longer in the winter, early spring, and late fall.
