How To Fertilize A Lawn - Tips For Fertilizing Lawns

Properly fertilizing your lawn should be one of the simpler and less time consuming processes in your lawn care program. While you could get very technical about it, the basics you need to know are not as complicated as they might appear to be. Listening to some lawn care professionals and gurus explain detailed processes and equations might leave you a bit confused about the whole deal. However, you don't need to know all the details to have a beautiful lawn.

How much to fertilize, how often, when, and what formula to use are all the right questions. However, because of all the different variables ranging from soil type to location to hundreds of grass varieties and types, it’s impossible to give an exact lawn care program that would fit every lawn.

Testing the soil isn’t usually necessary for determining lawn fertilizer needs. If you’re having trouble growing a lawn, testing may be helpful to figure Ph and to see if a nutrient level is extremely high or low. Otherwise, they don’t give a good indication of the amount of nutrients your lawn needs.

You generally only need to be concerned with the three basic nutrients of Nitrogen, Phosphorus, and Potassium. Other minor nutrients such as iron and zinc are usually plentiful in the soil. However, in some instances such as my own yard, I do apply one application of fruit and nut tree food to the entire lawn every few years. I have several trees that take these nutrients from the soil. Still it’s not common practice and isn’t necessary in most yards, landscaping ideas, and lawns.

The right formula? I can’t give an exact. Just a guideline. The three numbers on the label (0-0-0) represent the product percentage of the three nutrients in order, Nitrogen, Phosphorus, and Potassium. A good mixture would be high in Nitrogen, low in Phosphorus, and medium in Potassium. An example might be 10-2-5. This is one of those areas that can get technical. However, if you're not inclined to study up in this area, just keep applications low and safe. Keep Nitrogen, the first number, at 20 or below.

As my own rule for staying on the safe side, and in my opinion is a better way to feed a lawn, cut the amount in half and apply it twice as often or even less often. For some nutrients, plants will absorb all that is in the soil until it’s gone, grow very quickly, and deplete the soil before it’s time to fertilize again. A continuous feed is much better for the health of the lawn, reduces the risk of burning, and is easier to get an idea of what feeding program your specific lawn needs.

Again, all of this can’t be placed in a given formula for all lawn types. When to fertilize, of course, depends on your area, time of year, weather. Your soil type (clay, sand, etc) will influence many factors including how often and how much to fertilize. So it’s best to follow the steps of starting with less and working your way up. It also helps to keep a journal to keep track of your results.
