Our lawns are living things and, like all living things, they need food to grow. Sunshine and rain is not enough to make our lawn flourish. We need to feed them. And this is where lawn feeds come in. They are the food our lawns need to grow green and healthy. Lawn feed provides nutrients that are vital for plant growth. Without these extra nutrients, the grass falls back on plant food reserves in the soil which it quickly uses up. Eventually, we have a pale, unattractive lawn with thin blades.

Nitrogen, Phosphorus and Potassium are important nutrients needed by lawns in large quantities and are provided by lawn feeds or fertilizers as they also called. Feeding the lawn is a simple but dedicated task. You need to decide whether to go for chemical feeds or take the organic approach. Whatever choice you make in selecting your lawn feed, the well-being of your lawn is most important. As far as lawn feed is concerned, here are our best picks for you.
