Whether you need it for livestock or other uses, growing hay at home is a cheap and easy alternative to purchasing it in bulk. Depending on your preferences, you can use grass, alfalfa, or a mixture of both to make hay. Once you've grown your crop, all you have to do is cut, dry, and store your hay for use as needed. Given seven months and plenty of care, you're sure to have plenty of homegrown hay for your needs!
