Fall lawn care

by Caroline Brown

Don’t put your garden tools in the garage just yet. There’s still time for a few more garden projects. If you have a lawn, preparing it for winter should be at the top of the list.

Re-seed & repair. Early fall is a good time to re-seed your lawn or to repair bare spots. (This can be done in the early spring as well.) The warm days and bountiful rain ensure root growth and grass has plenty of time to mature before the ground freezes. But it’s best to do it before the middle of September, or the new grass may be damaged this winter.

Re-seeding your entire lawn is a much bigger chore than repairing bare spots, but the process is the same. Dig up 4-5 inches of soil in the area to be reseeded or repaired, and remove any weeds, rocks and other debris.

Buy good quality grass seed. Don’t go for the cheap stuff at the local job lot—they often have inferior seeds or use varieties of seeds that aren’t appropriate for our growing region. Choose a high-quality variety that’s appropriate for the level of sun or shade in your yard.

Scatter seed in the bared area and rake it into the soil. Keeping the newly-seeded area watered is critical to grass root development and growth. Water it right after you seed, and if it doesn’t rain, water it thoroughly in the morning and evening for three weeks. Covering the area with straw helps the soil retain moisture, but it’s not a must—especially if there’s a chance that the straw isn’t clean and carries weed seeds.

After two or three weeks, you’ll notice that the seeds have germinated and the grass is growing. Don’t mow the grass until it’s at least three inches tall.

Water. If you’ve had a rainy early fall like we have here in Rhode Island, it’s not necessary to water an established lawn anymore. Too much water encourages grass growth, which can be damaged when it freezes.

Whether you have an automatic irrigation system or you simply water using a hose and sprinkler, start reducing the weekly number of waterings now. Cut back now to two times a week and stop watering completely by mid-October.

Fertilize. If you haven’t fertilized your lawn since June or July, early fall is a great time for fertilizing with an organic fertilizer. Most local nurseries carry organic fertilizer, but if you can’t find any and must buy a chemically processed fertilizer, choose one that’s “slow-release.”

Organic and slow-release fertilizers release nutrients over a number of weeks, instead of dumping a big load of nutrients on your lawn all at once. It’s better to give grass nutrients over a period of many weeks, because anything that isn’t used right away will simply be washed from the soil.

Core Aeration. It’s a good idea to aerate your lawn every other year. It doesn’t have to be done in the fall; it can also be done in the spring.

Rent a core aeration machine—its blades dig into the soil and pull out “cores” of soil, grass, roots, and thatch. The holes it leaves behind allow water, fertilizer and air to circulate in the soil, enhancing growing conditions. Lawn aeration is especially helpful for yards with compacted soil.

  1. Wow, this lawn looks bleak!!!! Is it really that cold there already or was this taken somewhere else/previously?

    Stay warm!!! G 🙂

  2. I think this lawn is somewhere in Illinois, not sure what season…my digi.cam is still broken so I’m still borrowing photos! It’s cooler here but not that cold, at least not yet!

  3. In our area (Pacific Northwest), it doesnt rain in the summer, and the green-looking lawns are the ones that are watered (and usually, fertilized and chemically treated) all summer long. Not like the rainy summer of the Midwest and East. So the earth friendly lawns here are brown during the summer. Some would say that ‘brown is greener’ in this situation. Now that rain is starting, the lawn greens up. It does give a sense of season changing.

    I’ve been thinking about some of the ‘eco lawn’ seed mixes, and maybe plant that this fall.

    I do have a 10 foot by 10 foot ‘dog lawn’ that gets watered during the summer about once or twice weekly, to avoid killing the grass and keep the area smelling better. That DOES grow green, but obviously no fertilizer is needed there!

  4. Thanks for the Great Read Looking forward to more

  5. UI live in north Florida and they have water restriction here as well. It does seem that it takes a brown lawn to live green in this case.

  6. Intriguing post on winterizing a lawn during the autumn months. By scattering seed throughout any bared patches of grass found, growth may start to commence with a few weeks. Thanks for sharing.
