Fall Lawn Care in Heber Valley

What you do for your lawn in fall decides how it looks next spring. Cool nights and warm days make September and October the best time of year to aerate, feed and repair turf in the Heber Valley, while there is still time before snow covers it for the winter.

This guide from Country Gardens & Nursery covers aerating, overseeding, fertilizing and the last few chores to finish before the snow flies.

Why Fall Matters

Why Fall Is the Best Season for Your Lawn

Most Heber Valley lawns are cool-season grasses like Kentucky bluegrass, fescue and ryegrass. They grow roots hardest when air temperatures cool off but the soil is still warm. Feeding and repairing the lawn now builds deep roots that carry it through a long mountain winter and green up faster in spring.

Fall also brings fewer weeds and less heat stress, so new grass seed has a much better chance than it does in the dry heat of a Heber summer.

Step by Step

Your Fall Lawn Checklist

  1. Aerate compacted areas. Core aeration pulls small plugs of soil so air, water and fertilizer can reach the roots. It helps most on clay soils and high traffic areas. Aerate when the soil is moist but not soggy, and leave the plugs on the lawn to break down.
  2. Overseed thin spots. Seed right after aerating so it falls into the holes. In the Heber Valley, seeding works best from late August through mid September. If you missed that window, you can dormant seed after the ground cools in late fall so the seed sprouts with spring moisture.
  3. Apply a fall fertilizer. A late fall feeding, often called a winterizer, applied after the grass stops growing but before the ground freezes helps roots store energy for winter and an earlier spring green up.
  4. Keep mowing until it stops growing. Lower the mower gradually to about 2 to 2.5 inches for the last cut. Long grass mats down under snow and invites snow mold.
  5. Clear the leaves. Rake or mulch fallen leaves with the mower so they do not smother the grass under the snow.
  6. Winterize the sprinklers. Blow out your irrigation lines before the first hard freeze. Until then, water deeply about once a week if fall is dry.

Gray or Pink Patches in Spring

Snow mold shows up as matted, crusty circles when the snow melts. Prevent it by mowing short for the last cut, clearing leaves and avoiding heavy feeding early in fall. Most lawns recover with a light raking once the ground dries out.

How Long to Keep Watering

Grass still needs water in fall, just less of it. Water deeply and less often until you shut off the sprinklers, then hand water any new sod or seed during dry, warm spells. Our guide to watering smart in Heber explains deep watering in more detail.

Laying Sod in Fall

Fall is a great time to lay sod in the Heber Valley. Cooler weather means less watering, and the roots knit into the soil before winter. Prep the ground with good topsoil, and see our sod and turf page for options.

Topdressing Low Spots

Fall is a good time to fill low spots and topdress thin areas with a thin layer of screened topsoil or compost. Spread no more than about a quarter inch at a time so the grass can grow through it.
