Why is my lawn

LandscapingUpdated March 2026

The answer to 'why is my lawn' is that there can be several common causes for an unhealthy or problematic lawn, including drought, improper mowing, pests, disease, or poor soil conditions. Symptoms may include bare patches, discoloration, thinning, or excessive weeds.

Some solutions you can try at home include adjusting your mowing height and frequency, aerating the soil, overseeding, and applying the right fertilizer. However, for more severe issues like pest infestations or chronic disease, it's best to consult a professional landscaper who can properly diagnose and treat the problem.

Frequently Asked Questions

How often should I mow my lawn?

The optimal mowing frequency depends on factors like grass type and growing conditions, but a good rule of thumb is to mow once a week during the peak growing season.

What's the best way to aerate my lawn?

Lawn aeration is best done in the fall using a core aerator machine that removes small plugs of soil, allowing better air, water, and nutrient penetration.
