Lawn food selection starts with the grass species and the soil beneath it. A soil test can identify nutrient shortages and pH conditions that fertilizer alone may not correct. Check the granular fertilizer label for the nitrogen source: slow-release nitrogen feeds over a longer period, while soluble nitrogen becomes available more quickly. That distinction helps you plan feeding around the lawn’s growing season.

Lawn fertilizer selection

Liquid fertilizer needs an application method suited to its label, with coverage measured across the treatment area rather than judged by spray time alone. Some states and municipalities in the United States restrict phosphorus use on established lawns, so check local rules before selecting a formula. Sweep stray granules off pavement and back onto the lawn, and keep fertilizer out of storm drains.

What do the numbers on a fertilizer label mean?

The N-P-K numbers show the percentages of nitrogen, phosphate, and potash by weight. Compare that analysis with your soil test recommendations rather than choosing the highest numbers.

When should I feed an established lawn?

Match feeding to the active growth period of your grass species. Avoid fertilizing dormant or drought-stressed grass, and follow any seasonal restrictions that apply locally.

Can lawn fertiliser be stored between applications?

Keep it in its original labeled container, out of reach of children and pets. Follow the storage instructions, including protection from moisture for granules and any temperature limits for liquids.
