When is the Best Time to Fertilize the Lawn?
Fertilize when the roots are growing!
When to apply lawn fertilizer is almost as important as the fertilizer you apply. Leading scientists recommend applying nitrogen fertilizers in the spring and fall for cool season grasses like Kentucky Bluegrass, Fescue and Ryegrass, and throughout the summer for warm season grasses like St. Augustine and Bermuda, since this is when the grass plant is actively growing.
The recommended timing of fertilizer applications by season is as follows:
Spring Lawn Care: April–May
The best time to apply fertilizer in spring is when soil temperatures have warmed and the grass plant is actively growing. A general rule of thumb is after the first 3 mowings. Apply 0.5 to 1 pound of nitrogen per 1,000 square feet to the lawn to support growth and to build-up nutrient reserves, which help the lawn withstand the heat and stress of summer. If you are using a weed and feed fertilizer, timing is much more critical to get the best results from the weed control. Be sure to read and follow application directions carefully.
Summer Lawn Care: June–August
Cool season grasses, such as Kentucky Bluegrass and Ryegrass, should not be fertilized in summer.
Warm season grasses do need fertilizer in the summer.
Fall Lawn Care: September–November
The most important time to fertilize your lawn is in the fall to help you lawn develop a strong root system. Apply 1.5 to 2.5 pounds of nitrogen per 1,000 square feet. Use a lawn fertilizer with a higher amount of nitrogen, if your grass type is Kentucky bluegrass or perennial ryegrass, or soil is sandy, or grass clippings are not returned to the lawn.
Although most homeowners do not need to worry about putting products down during the cold, winter months, there are a few winter weather tricks. Your lawn is dormant during winter, meaning it won't actively grow. However, that doesn't mean you can't do damage to it. Walking on frozen or snow-covered grass can break the grass blades and compact the soil.
Compacted soil does not allow water and nutrients in when the lawn starts growing again, and can lead to weed infestation and dead grass. Breaking the grass blades removes the plants protection from the elements and can make greening up in the spring take longer.
