Best Lawn Fertilizer Schedule: When to Feed Grass

Fertilizing your lawn is an art and so should your lawn fertilizer schedule. When doing so there are two vital factors to consider. They include how much fertilizer to apply and when to apply. However, the basic rule dictates that applying about three pounds of nitrogen in each 1,000 square feet per growing season is the ideal measurement.

The above measurement is ideal for Kentucky bluegrass or when the grass is mixed with a perennial species of ryegrass or a fine fescue. Otherwise, other great species of grass that may also require an ideal Grass fertilizer schedule include St. Augustine, Bermuda and Zoysia. All the same calculating percent nitrogen in the bag and the size of your lawn (in square feet) can be done in many ways.

The easiest method that you could use is dividing the rate of nitrogen desired by the percentage of nitrogen in the bag and the resulting figure will then be multiplied by the square footage of the lawn and divide by 1,000.
