Lawn fertilization isn't difficult. All you need is the right fertilizer applied in the proper strength as frequently as possible.
I was surfing through a few competitor's websites where they try to make it complicated with 5 or more different fertilizer types to meet the different needs of today's sophisticated homeowner. All they do is fertilizer grass. I think they make it sound complicated so they can charge more for it.
Virid takes a different approach. We feed lawns (and other landscape plants) automatically, naturally. We use the sprinkler system to feed and water at the same time a very dilute amount of fertilizer that encourages productive soils and healthy plants. Healthy plants crowd out weeds, fight off disease and are more drought tolerant so they require less water. In short, healthy lawns (and other plants) don't need all the other treatments offered because they can take care of themselves most of the time (if they are healthy). That is the natural cycle and plants have been perfecting it for decades and centuries and longer.
Virid can afford to feed your lawn (and other plants) 70 times a growing season because the system is automatic. There is no need to trick nature into believing monthly services with complicated feeding regimines are appropriate when, with the right approach, we can work with nature and let the lawn take care of itself.
