Before you start the process of feeding your lawn, it’s important to know what type of grass you have. While the above schedule is specifically for cool-season grasses, it’s beneficial to know that the type of grass you have will help determine the appropriate time to fertilize your lawn.
Cool-season grasses, such as tall fescue, Kentucky bluegrass, and perennial ryegrass, should be fertilized two to three times during the growing seasons (twice in the spring and once in the fall) preferably early in the morning or before air temperatures rise above 60 to 70ºF.
Warm-season grasses, such as Bermuda, St. Augustine, and Zoysia, should be fertilized during early spring to early summer, just before the temperatures rise above 80ºF and peak growing season starts (late May to early July).
Another factor to be mindful of when feeding your lawn is the temperature of your soil. When applying fertilizer, the soil temperature should be at least 45ºF and air temperatures should be no higher than 85ºF. It is important to fertilize when your soil is at the right temperature to avoid damaging your lawn. Applying fertilizer in high temperatures can make your lawn more susceptible to burning. You can use a soil thermometer to determine if your soil is at the right temperature for feeding your lawn, which can be found at your local hardware store or garden center.
Watering Your Lawn
While applying fertilizer to your lawn, you should be mindful of your current watering schedule, as some fertilizers require your lawn to be dry before an application. If you’re watering your lawn on a consistent basis, you should only adjust your schedule when necessary. For example, fertilizers containing broadleaf weed killer, such as Jonathan Green Weed & Feed must be applied to a damp lawn so that the weed control can adhere to the grass leaves.
Follow Directions Carefully
Adding fertilizer to your lawn care routine can provide many health benefits to your lawn. It can, however, be damaging to your lawn if you don’t carefully follow instructions. Always remember to read and follow all instructions on the back of your fertilizer bag, as no two fertilizers are the same and each requires a different technique for application.
Make sure you are applying the correct amount of fertilizer to your lawn, as applying too much could lead to lawn problems, such as burning or yellowing of the grass. Over-application of fertilizer can also present environmental concerns, such as runoff into your local water supply.
A good rule of thumb is that more is not always better. You want just the right amount of fertilizer at the right time of year to ensure your lawn gets the best results.
As you care for your lawn throughout the year, you may encounter some common lawn issues, such as grubs and lawn fungus. Be mindful of the amount of product you’re applying in conjunction with feeding your lawn, as you don’t want to apply too many products at once.
Remember this: For a green lawn, feed your lawn! Fertilization is a key part of any healthy, lawn care routine. Using a proper schedule, technique, and being mindful of any possible problems that may arise will help you successfully feed your lawn and give you a lawn to be proud of.
