Five fall yard care tips

Posted by Scott Stueber on Oct 14, 2014 10:16:00 AM

Expert Interview Marv WolfIf you’re like me, you take pride in how your lawn looks during spring and summer. Proper lawn maintenance during the growing months includes cutting, trimming, watering, and fertilizing.

What about when fall approaches? Do you still maintain your lawn the same way or do you think your lawn needs less care? If you think your lawn needs less care in the fall, you’re wrong.

In this week’s blog, I had the privilege of interviewing Marv Wolf, West Bend’s grounds supervisor. Marv has been the grounds supervisor for 23 years and is responsible for planning, coordinating, and maintaining our 160-acre corporate campus. This includes 50 acres of restored prairie, 2 acres of restored wetlands, 10 acres of restored woodlands, and 3 miles of walking trails.

Here are Marv’s tips on how to take care of your lawn this fall.

Q: Keeping your lawn a longer length during the summer months has many advantages. During the fall months, should you maintain a longer length or should you cut it shorter?

A: The recommend grass length for our area is 3 – 3 1/2 inches. Keeping grass at a longer length during the growing season promotes a healthier lawn; however, as the grass-growing season ends, it is a good idea to reduce the length.

The benefits of having a shorter lawn for winter are:

1. It may prevent meadow voles. Meadow voles like to borough in longer grass and can cause damage during the winter months. If you keep your lawn shorter, they may not take up winter residence in your yard.

2. The weight of snow can push down on the grass and cause disease. If your lawn is shorter, you ‎can minimize the risk of disease.

Remember, you don’t want to shorten the length of your grass all at once. Slightly lower your blade for the first cut and then lower it again for the final cut, taking off no more than a 1/3 of your current height. Removing too much of the turf at once can cause undue stress on your lawn.

Q: What is the purpose of lawn aeration and should it be done every year?

A: Over time, the soil under your lawn compacts which minimizes air space. Minimized air space makes it more difficult for water and nutrients to enter the soil. Core aeration is the process of removing plugs of soil, resulting in many holes in your lawn. There are several benefits to this process:

1. As the soil plugs break down, beneficial enzymes go back into the soil.

2. The holes in your lawn make it easier for water, light, and nutrients to get into the soil, promoting deeper root growth.

3. These enzymes also help break down thatch in your lawn. Too much thatch in your lawn prevents water and nutrients from getting into the soil. If you’ve never had your lawn thatched, it’s a good idea to thatch and aerate.

The best time of year to core aerate is in late spring or early fall when the grass is actively growing. Depending on how your lawn responds, you only may need to do it every other year.

Q: If I have bare spots in my yard, should I take care of them now or wait until spring?

A: This is a perfect time of year to fix bare spots in your lawn. All you have to do is roughen up the soil with a garden rake and apply your grass seed. Then water the spot(s) every other day for a couple of weeks.

Q: Should I fertilize my lawn anymore this year or wait until next year?

A: Fertilization is important because it adds essential nutrients to the soil which promotes healthy growth. Marv recommends fertilizing your lawn three times a year: on Memorial Day, Labor Day, and Halloween (or after the lawn has gone dormant).

The Labor Day treatment is important because as the fall season progresses, weeds and grass are both fighting for the nutrients in the soil. When you apply a fertilizer with a herbicide, nutrients are absorbed in the soil while the herbicide kills off the weeds.

Finally, if you’re only going to do one treatment a year, Marv recommends doing it around Halloween. A fall application provides essential nutrients that promote deep root growth and provide a nutrient boost. This nutrient boost can help jump start your yard the following spring.

Please note that the ground should not be frozen when your last fertilizer treatment is applied because the fertilizer will not be able to get into the soil.

Q: Should I continue watering my lawn and trees?

A: If your lawn is actively growing, you should continue to water it. You can discontinue watering after you cut your lawn for the last time.

As for the trees, if you’re experiencing a dry fall season, you should continue to water your trees. Evergreens should be watered until the ground freezes. The more water that goes into the root system now, the better the tree will do during the winter months.

Evergreens transpire during the winter months. Winter months that are sunny, but extremely windy and cold can cause the needles to turn brown. This was especially true during the winter of 2014. Many evergreens were damaged and many are still trying to make a comeback.

In Wisconsin, the average date for the first frost is October 22. Frost that settles into the ground and doesn’t come out usually occurs mid-to-late November.
