I have used this product with great results in Texas and have heard numerous positive comments from other organic gardeners that use it. When you use it, water first and then the last thing you should spray is the Hasta Gro Lawn for it to work the best. This fertilizer is not only for short term looks. Medina helps long term soil health and starts to let the soil take care of itself so you will need less fertilizer over time. They did experiments in barren fields years ago and it helped at the time, but now, years later, the area that they used it on is the only green in the fields.
