If sulfur is needed, add 1/2 part of gypsum. If feather meal is available, use that instead of the blood meal to achieve a slower release of nitrogen. This mixture should be spread on a lawn at a rate of 4-8 pounds per 100 square feet, preferably twice in the fall and once in the spring.
Basic Garden Mix (5-5-3)
