<p>I've operated a non-toxic lawncare service since 1995 in northern Indiana and have found that for the vast majority of cases, materials that pose virtually no risk to the customer, his kids or his pets are available, effective and affordable. <p>Insecticidal soaps & oils are extremely effective but require operators to do more than show up and hose down the landscape. Weeds in lawns can be an insurmountable problem if the turf is thin and the customer insists on a 2" mowing height. But then again, that same lawn would still have constant weed problems even with the use of standard herbicides. <p>My approach of providing optimum growing conditions for the desired plant and treating pests with materials that pose minimal risk to the customer and his family isn't for everyone. Some people won't tolerate anything but the lowest price. I've found they aren't on my customer list very long regardless at which point I price them.
