Autumn Grass Care Tips from Your Denver Landscape Service Experts


September 21, 2016

Homeowners tend to turn their attention away from their lawns as autumn arrives, because preparing the home itself for the coming cold months seems like a greater priority. But autumn is a crucial time of year for grass. As your Denver landscaping service experts, one of our goals is to offer you information you can actively and immediately use, so here are some grass care tips for autumn.

Using a fertilizer not specifically designed for fall is a mistake many homeowners make. Fertilizing in the fall is tremendously beneficial for a lawn. It helps the lawn survive the winter by encouraging enhanced root development and carbohydrate production and storage. But if you use any old lawn fertilizer that happens to be lying around your garage or on sale at the store, this fertilization could mostly stimulate top-growth, which means the visible blades of the grass could become taller. That’s a problem, because if grass blades are growing significantly in autumn, they are not hardening off and undergoing the natural changes that help grass survive the cold of winter.

One fall lawn care secret is to use a fertilizer specifically designed for autumn. And granular fertilizers are better than liquid fertilizers in fall. Fertilize before your lawn changes from its usual green to a browner winter tint. If you wait too long and your lawn is already brown, skip fall fertilization. When a lawn turns brown for winter, it stops taking in nutrients. At that point, spreading fertilizer is a waste of time and money.

Mother Nature typically provides most or all of the water a lawn needs in autumn. Providing more water than a lawn needs as winter approaches could prevent the grass from hardening off to protect itself, so don't overwater. Lawns do best when there is a gentle weaning off from summer watering. As temperatures start to drop, gradually reduce the amount of water. By October, you probably should water only if there is an exceptionally warm, dry spell. If you have an irrigation system, stop running your preset summer watering schedule and instead turn on the system only as necessary.

Don't cut your grass shorter for fall. Some homeowners lower their mower-blade height in autumn because it is easier to rake leaves off of short grass. This also lowers the odds of winter
snow mold problems. But when you cut grass blades short in autumn, you rob them of their capacity to convert sunlight into nutrients – nutrients they need to store to survive the winter. So, mow your grass the same height in the fall that you do throughout the spring and summer, because the advantages of mowing shorter are not worth the potential for long-term damage.
