Picking a Fertilizer for Your Lawn

When you’re choosing a fertilizer for your lawn you’ll want to make sure you choose the right feed for the task at hand. Here are a few checkpoints you should tick before committing to your purchase:

Grass Type

Make sure you read the packaging and can be sure that the lawn feed is suitable for use with the type of lawn you have. If in doubt, you’re best off selecting a lawn fertilizer that’s suitable for all types of grass.


You need to make sure you choose a fertilizer that’s designed to be used in the summer. You can get fertilizers that are suitable for use all year round as well as fertilizers that are designed for specific seasons of the year. Choosing a fertilizer designed for the wrong time of year could mean it’s useless as it’s probably designed for different conditions.

The great thing about choosing a fertilizer for summer is you can get additional features specific to the season such as protection against burns and insects.

Fertilizer Analysis

Look out for the three numbers associated with lawn fertilizers, for example (16-4-8). The series of numbers appears meaningless to the unknowing gardener but they’re really significant. The first number, 16 in our example refers to Nitrogen (N) which helps with your plants’ growth above the ground. The second number, 4 in our example refers to the Phosphorus (P) which helps establish the growth below ground. The final number, 8 in our example refers to the Potassium (K) which is important for the overall health of the plant.

So how does this help you? The numbers tell you a lot about how the fertilizer functions. Numbers that are close together (such as 10-10-10) work as an all-round fertilizer, with fertilizers that are higher in one particular area focusing more on that aspect of growth. We won’t go into further depth on this (that’s for another article) but in the meantime, you can read more on fertilizer analysis here.
