Benefits of Fall Aeration - Should I Aerate My Lawn in the Fall?
Since most lawns need to be aerated every year, homeowners typically choose between spring
aeration and fall aeration because those are the two best times to aerate. Between March and
May (April is often best) and September to October (late September is usually ideal) are the
best conditions for a superior aeration job. People often ask me if they should aerate in the fall.
In an attempt to answer their questions I have written the following article. Fall aeration provide benefits that are not seen in the spring and it may be a better time for your lawn. Consider whether your lawn would be improved by the following benefits of fall aeration.
Better dirt plugs when core aerating.
The ground in fall is usually soft enough to get decent plugs but not too soft. The spring in many
areas is so wet, that it can be hard to find the right time to aerate because the ground is saturated much of the time. Aerating when the ground is too soft results in holes that close-up quickly and don’t provide improved access to nutrients, water, air and fertilizer for very long.
Best time for overseeding.
Because aeration creates additional space in the soil and reduces compaction, it is a good idea
to overseed after aerating. Fall is the best time for overseeding because there is plenty of rain to
help the new seed come in with little effort and without spring weeds.
Improved lawn drainage.
Lawn Aeration is vital for good lawn drainage and helps reduce runoff. Fall aerating can be done with
lime or sand to further improve drainage.
More benefits from fertilizer.
It is a good idea to fertilize your lawn after aerating as more will reach the roots. Fall aeration
increases the benefits your lawn with get from both fall and winter fertilizing.
Great as part of winterizing your lawn.
Fall aeration makes it easier for your lawn to do well over the winter months and come back
beautiful in the spring. A great hint for overseeding in the fall is to use a good shade seed to
prevent moss growth over the winter.
