No Mow Grass
No Mow Grass is a commercial site that sells this product, but it also has plenty of information about exactly how to make this move to a more ecologically sound lawn. You can find answers to questions such as how much seed to order, when the seed should be planted, how to use it over an existing lawn, how to maintain it once established, and how to deal with problem soil.
Alternatives to Lawn Grass
The Wild Lawn Handbook: Alternatives to the Traditional Front Lawn by Stevie Daniels, former editor of Organic Gardening Magazine, is a treatise on releasing yourself from the tyranny of a constant-care lawn. She gives information and advice on lawns created from native grasses, wildflowers, ground covers, and moss. She discusses in detail meadows and prairies and backs up her advice on how to reduce your input with photos of each type of lawn. This is a good by-the-fire read on a winter night. It will inspire you to take steps to turn your lawn into an ecological plus.
