Frequently Asked Questions (FAQs)

1. What is the best fertilizer ratio for spring?

What is the best spring lawn fertilizer? Lawns want nutrients in a basic ratio of 4-1-2. (NOTE: 16-4-8 is a 4-1-2 ratio) This means four parts nitrogen to one part phosphorous to two parts potassium.

2. When should I fertilize my lawn in the spring?

When To Apply Spring Fertiliser: The best time to start feeding your lawn is generally mid-spring (often late March to April) before the heat of the summer when the soil temperature reaches around 12C. You can tell when the soil has warmed up because the lilacs begin to blossom and the grass starts growing.

3. What is the best month to fertilize your lawn?

Ideally, the ground should be around 55 degrees Fahrenheit. Depending on where you live, March to April is the best time to fertilize your lawn. It's also best if your yard is watered a few days before you want to apply the fertilizer, whether that's from rain or a sprinkler.
