Complete fertilizers are fertilizers specially formulated to contain all of the three essential nutrients (nitrogen, phosphorus and potassium), mixed in balanced proportions.

These blended fertilizer formulas are very economical and convenient. You may also be able to find special fertilizers made for a certain type of plants (for example, a certain grass type).

There are many commercial brands selling complete lawn fertilizers, so you will be able to choose between different products.

Tips for Buying a Complete Fertilizer

There are some things you need to pay attention to when buying lawn fertilizer. First of all, it's important to check how much of the actual plant food it provides. According to the law, all fertilizer manufacturers have to list on the product (on the label or container) how much nitrogen, phosphorus and potassium (in percentages) a mixture contains.

The percentages are displayed on the package in the form of three numbers separated by hyphens. For example: 5-10-5. It means that this particular fertilizer formula contains 5 percent nitrogen, 10 percent phosphoric acid and 5 percent potash (or potassium).

Don't forget: the ratios are always displayed in this order. It's always nitrogen first, phosphorus second and potassium third. There are many different ways to mix these ingredients, so you will find a wide range of numbers (percentages) displayed: 10-10-10, 10-30-20, 12-6-4, and more.

To make your lawn all strong, green and healthy, it's important to use a good fertilizer. What gives a lawn that lush green color is nitrogen. So choose a fertilizer with a high percentage of nitrogen. One thing to keep in mind is that the higher the number, the more expensive the fertilizer will be. On the other hand, the more nitrogen there is in the fertilizer mix, the less fertilizer you need to use to get the best results.
