Bob Vila Radio: Figuring Out When to Fertilize

The best time of year to fertilize lawn grass? Well, that depends.

When’s the best time to fertilize your lawn? Opinions do vary but generally speaking, most agree that it’s best to fertilize grass during periods when it’s actively growing.

Listen to BOB VILA ON FERTILIZING THE LAWN or read below:

The growing season for lawn grass depends on two variables: where you live and what type of grass you have.

In the U.S., there are many different types of grass blanketing homeowners’ front yards, but they’re often divided into three classes: warm-season grasses, cool-season grasses, and transitional grasses (the latter thrives in the middle part of the country).

If you’re not sure which type you have, take a small square to your local nursery or have a landscaper take a look.

The main growing season for cool-season grasses is in the spring and fall. Such grasses do best with a robust feeding in the fall and a lighter feeding in the spring.

Warm-season grasses do their thing in late spring and summer, and it’s best to feed them in the spring, just as you see new blades of growth coming in.

Whatever fertilizer you use, be sure to follow the manufacturer’s instructions closely. Otherwise, you may end up with more brown than green!
