If you walk the aisles of any big box home improvement store you will see tons of products for lawn care.
The problem with these products is they are a temporary solution and will create even more problems down the road.
Never use chemical pesticides as they are all poisons and are dangerous for your health, your plants, and your pets.
Non-organic products usually contain high salt chemical fertilizers that will burn (stress) your lawn and plants, destroy soil health (stress) and invite more problems to happen.
Only use Organic products on your lawn and garden. Treat the soil first and the results will follow!
