Spring Fertilizer: Why, When, What, And How?

Fertilizing your lawn is one of the most important lawn care tasks you’ll take on this year and it’s one of the first steps you need to take in preparing your lawn for a successful growing season! Unfortunately, it’s also one of the most misunderstood lawn care tasks, especially during the early spring months.

Why Do I Need Spring Fertilizer?

Three reasons why spring fertilization is so important are:

  • Winter recovery – A spring fertilizer application will help your lawn recover quickly following the harsh Michigan winter. Fertilizing will allow any nutrients that were depleted over winter, to get replenished just in time for the growing season. A fertilizer high in nitrogen and potassium will provide your grass with those important nutrients, along with others.
  • Root system development – Fertilizing in the spring allows for your grass’ root systems to deepen and develop. This will significantly improve the grass’ strength during the hot summer months, where drought becomes a risk.
  • Natural crabgrass control – A thick, healthy lawn is one of the best ways to prevent crabgrass from taking over this spring. Fertilize now and don’t even give those pesky weeds a chance to start growing!

When Is The Best Time To Apply Spring Fertilizer?

Fertilizing too early in the spring is essentially useless. If the ground is still frozen (or thawing), the fertilizer will not penetrate the soil, and it won’t reach the roots. As a general rule of thumb, you want to wait until the temperature reaches at least 50 degrees. When the grass starts growing, and the flowers start blooming, it’s prime time to apply that spring fertilizer.

What Is The Best Type Of Fertilizer To Use In The Spring?

A slow-release fertilizer that is high in nitrogen is going to be the best type to use in the spring. This will allow your grass to receive a steady amount of nutrients over an extended period of time. The nitrogen will aid in the photosynthesis process, resulting in healthy and thick grass. Beware: the more nitrogen there is in the fertilizer, the quicker the grass will grow, and the more often you will need to mow!
