A Few Techniques for a Happy Fall Lawn

With the arrival of October tomorrow, the end is in sight, well at least the end of summer. The hot humid days of September have given way to the moderate temperature readings courtesy of recent weather events.

Days have shortened noticeably and the plants have noticed. Foliage growth has slowed and seed production is in overdrive.

As the season slowly shifts, the care-related needs of the lawn and landscape are changing too.  Inputs needed six months ago and environmental factors which were true in the spring are now being altered by the immutable and timeless forces of nature.

While yard work is important to maintain an attractive lawn, if done successfully, the resident can spend quality time in other pursuits like watching the wildlife from the comfort of the front porch.

Fertilizer is one factor which must be considered in light of the dormant season’s approach. Inappropriate or excessive application will waste resources and end up in the water supply where it will do no good.

As many warm season grasses and plants are reducing their growth rates to prepare for winter, the need for nutrients slows. Nitrogen, the first number on a fertilizer tag’s list of ingredient percentages, is especially vulnerable to misuse by the well-intended but inexperienced or uninformed person.

Over application of nitrogen will promote the aggressive growth of tender green foliage in the lawn. If a frost or freeze occurs when the tender vegetation is present, the plant will experience excessive damage or death.

The directions on home and garden fertilizer bags and soil test reports all recommend restricting or eliminating nitrogen application late in the growing season. This is sound advice.

Herbicide use changes in the autumn also. As with misapplied fertilizer, misused herbicides will waste resources and can end up in the water supply.

Weeds and other targets of herbicides must be actively growing for the herbicide to work effectively. Autumn can present challenges to effectively applying herbicides.

Plant growth decelerating towards dormancy will not absorb as much herbicide and may, species depending, be completely immune.

Herbicides also do not work on plants which are under drought stress. It is important to remember October can be a dry month in panhandle Florida, nature’s way of forcing a fall growth shutdown.

Yard waste and grass clipping will help refresh mulch in flower beds and on tree root zones.  The summer heat and humidity have combined with bacterial activity to break down the current supply of mulch.

The on-site utilization of yard waste as mulch or as a basis for compost is a good practice to establish. It will benefit the landscape and reduce the multiple layers of expenses required to collect, haul and dispose of this material.

If properly composted, the material reduces the chances of introducing weeds, insects and diseases which can be on commercial products. Another way to look at the subject is “What is produced in the home landscape stays in the home landscape… and saves everyone money in the process.”

While October’s early weeks have the potential to be just as oppressively hot and humid as August, relief is on the way.  Be ready to spend the cooler days enjoying a private bit of paradise in this region without worrying about problems which could have been avoided.
