Feeding Your Lawn
The amount of fertilizer for any particular lawn depends on the fertility of the natural soil, the degree of growth you want, and the type of grass that you are growing.
Bluegrass requires from 2 to 3 kilograms of actual nitrogen: 1 to 1.5 kilograms of actual phosphorous, and the same of potasium per 100 square metres per year. Fertilizer applications are determined by the amount of nitrogen they contain, because nitrogen is the most difficult of the three materials to handle. We recommend any special turf type fertilizer made by a reputable manufacturer using a controlled release nitrogen. This will provide you with a well balanced feeding for your lawn and the fertilizer will release slowly. You should apply about half the annual amount in the spring, and the remaining half in the early summer and fall. Be sure to follow the instructions on the bag. Always water the fertilizer in to prevent burning.
