Yard care tips for the fall

Fall is one of the best times to improve your lawn, trees, shrubs, and garden. The basic maintenance you do during this “second spring” will pay off in healthier growth and fewer problems next year.


Mulch Your Trees

Now is the time to add a layer of mulch around your trees. In the winter, mulch insulates the roots and provides nutrients. It helps the soil retain moisture, too. Even large and old trees benefit from adding a ring of mulch.

The mulch should not touch the base of the tree.

Mulch should not touch your tree.

  Apply mulch to a ring around the tree trunk. Remember the Rule of 3:
  • The mulch ring should extend 3 feet out from the trunk
  • The mulch should start 3 inches from the trunk so that no mulch touches the tree; and
  • The mulch should be 3 inches deep (but not more).

Start Organic Lawn Care

A beautiful lawn next spring starts with simple actions you can take this fall.

Learn from your soil. Whether it’s through weeds, or empty patches, the look of your lawn tells you about the health of the soil. The soil should be loose and teeming with life too small to see—if your lawn is suffering, start with aerating your lawn, adding compost, re-seeding, and leaving all your grass and leaf clippings as a source of nutrients.

Replace your “weed and feed” chemicals with grass seed. Fall is the perfect time to restore bare patches of lawn with seed—do this every year to fill in your lawn, because a strong carpet of grass will keep weed seeds from germinating.

3 ways to prep your lawn for winter.
  1. Dethatch (remove thick mats of dead grass down at the ground level).
  2. Aerate the soil (add small holes) to allow water and nutrients to penetrate.
  3. Add compost.

Recycle Your Yard Trim

During the fall, your yard becomes covered with leaves. What should you do with these leaves and other types of yard trim?

Compost It. Take leaves, grass clippings, and garden prunings, and recycle them into a nutrient-rich soil amendment, better known as “black gold” or compost.

The Montgomery County Department of Environmental Protection provides compost bins at no additional charge to residents of the County.  Simply add leaves, grass clippings, and garden prunings into the compost bin, add water, and mix the materials periodically. Then, let nature do its thing.  Over time, microorganisms will feed on the organic material, leaving you with compost you can add to your soil.

Recycle Yard Trim Properly. If you receive Montgomery County-provided recycling collection service, and you don’t have the space to compost, place your yard trim out for weekly curbside recycling collection.  The County collects yard trim year-round. Place yard trim in paper yard trim bags, in reusable containers labeled with a yard trim sticker, or bundle with twine.  Please note, yard trim cannot be placed in plastic bags.

For more information about the County’s yard trim recycling program or where to get a compost bin, visit montgomerycountymd.gov/yardtrim or call 3-1-1 or 240-777-0311.

Thanks for these tips for caring for a yard. You mentioned that you should try to have a mulch ring around a tree that is 3 inches deep. I wouldn’t mind knowing if this a general rule or if specific trees could benefit from more or less mulch.

Thanks for your question, Taylor! It is a good general rule to follow. We recommend keeping the mulch 3 inches deep for all trees, as long as there is a barrier of 3 inches between the tree’s trunk and where the mulch starts. Think of it as creating a doughnut of mulch, surrounding the tree (this handout has some useful pictures that illustrate that idea: https://www.montgomerycountymd.gov/green/Resources/Files/trees/Mulch-Flyer.pdf.

If you are wondering about a specific type of tree, let us know and we will get back to you. Hope this helps!
