Fertilizing At The Wrong Time

How To Fertilize Your Lawn | The Home Depot

“Many homeowners don’t follow a lawn fertilizer schedule. They fertilize when they think their lawn needs it, when they have time or when the stuff is on sale.

Here’s when to fertilize lawn: If your lawn fertilizer schedule is once per year, apply it around Labor Day. Thats when your lawn is the hungriest and when it will respond best to the nutrients it receives. Fertilizing at this time will help replenish food reserves after a long, stressful year of growing and before the harshness of winter sets in.

If your lawn fertilizer schedule is twice per year, apply the second application about the middle of October. This acts like a second helping of much-needed food going into winter. A third application can be added in mid to late spring and can be combined with your crabgrass preventer. A fourth application, if you feel the need, can be added mid-summer. Watch the weather when applying midsummer fertilizers. Fertilizing during hot, humid weather can harm your lawn. An exception would be using an organic fertilizer. They are much more lawn friendly during the dog days of summer.

In the spring, apply just enough fertilizer to help green up your lawn. About half the normal amount will do. Even without fertilizer, your lawn naturally grows quickly as soon as temperatures become consistently higher. Have you ever noticed that grass grows fastest in the late spring and early summer? Why promote even more growth at this time by fertilizing?

Types Of Fertilizer To Use On Lawns

Here are the basic types of fertilizer to use on lawns:

Slow-release You dont have to use slow release fertilizers as often, but they are usually more expensive.

Fast-release You get quick results with a fast-release fertilizer, but you have to apply them in smaller amounts and more frequently. You can burn your lawn with a fast-release fertilizer if you use too much.

Weed and feed Try to identify your weeds before using a weed and feed product and make sure your weed is listed on the product label. Take special care around trees, shrubs, and garden plants.

Organic materials such as compost and manure The essential nutrients arent as concentrated in these types of materials, so you have to use a lot. Compost or dry manure before applying it to the lawn, and be aware that some manures, particularly horse manure, may contain weed seeds.

Liquid fertilizers These arent recommended because they are hard to apply evenly and require frequent applications.

Using A Handheld Broadcast Spreader

A handheld broadcast spreader works well for fertilizing small lawn areas. Walk evenly and slowly, and be sure to overlap distribution patterns slightly with each pass. A small spreader like this also works really well when you have shady areas in your lawn that require a different fertilizer rate than the sunny sections. Some fertilizers combine an herbicide with the lawn food. These products are sold as weed-and-feed lawn care products and are applied using a lawn spreader.

Bulletin #2154 Fertilizing A Home Lawn In Maine

For information about UMaine Extension programs and resources, visit extension.umaine.edu.Find more of our publications and books at extension.umaine.edu/publications/.

Many Maine homes are near ponds, lakes, rivers, and coastal waters, or near ditches and storm drains that can carry pollutants to these waters. Even bodies of water that are miles away can be polluted by excess nutrients such as nitrogen and phosphorus found in common fertilizers we use on our home lawns. The threat of pollution is greatest when these fertilizers are over- or improperly applied. Groundwater can also be contaminated by lawn fertilizers that leach downward. Recent research has provided information that should change the way we choose to fertilize our lawns.

Cool Season Vs Warm Season Grass

How to Fertilize Your Lawn

Warm season grasses thrive in warm-weather regions, such as the southern United States. It’s best to feed warm season grasses in warm weather as they grow most actively during the heat of summer.

Popular warm season grasses include:

  • St. Augustine: Broad dark green blades with a rounded tip
  • Zoysia: Prickly, stiff and narrow blades form a carpet-like lawn
  • Centipede: Pointed blades with a notch that grows to be dense and soft

Cool season grasses do best where there are extreme temperature fluctuations, such as those in the North, Northeast and Pacific Northwest.

In the North, where cool-season grass types are popular, lawns need to be fed four times a year with each feeding six to eight weeks apart. If your lawn is still green and actively growing in the summer, you can continue to feed it throughout the summer months at the same rate. However, if your grass turns brown during summer heat and drought, temporarily stop feeding until it starts to grow and turn green again in the early fall.

Popular cool seaon grasses include:

  • Kentucky Bluegrass: V-shaped with pointed blades, dark green and soft
  • Perennial Ryegrass: Pointed blades with visible veins
  • Tall Fescue: Dark green, coarse, wide pointed blades with visible veins
