Fescue is a grass that can grow tall enough to be collected as a type of hay if properly fertilized. It is considered a poor man's hay by many farmers, but if properly cared for and if harvested early enough, fescue hay can provide the proper nutritional balance for cattle, horses and other farm animals. Proper fertilization is a key component.
Fertilize your fields with nitrogen in early February if you plan to grow fescue hay. This is especially important if you plan more than one cutting during the growing season. Spread a minimum of 60 to 80 lbs. of nitrogen per acre of land.
Add more nitrogen to the soil immediately following your spring cutting if you plan at least one more cutting during the summer or fall season. Spread another 60 to 80 lbs. of nitrogen per acre.
Spread a combination of nitrogen, phosphorus and potash following the final harvest of fescue for the year. This conditions your soil for the following year. It is important to replenish the soil in this manner as fescue tends to remove many soil nutrients during its growing cycles.
