Don’t Pull Those Tomato Roots, The Fall Garden Cleanup Trick That Pays Off

When tomato season comes to an end, most gardeners instinctively grab the plants by the stem and pull them straight out of the ground. But there may be a better way to clean up your garden that you will see the benefits of come springtime: simply cut the plants off at soil level and leave the roots behind.

Tomato plants develop an extensive root system during the growing season, reaching deep into the soil for water and nutrients. When you pull the entire plant, you also pull that root structure out with it, disturbing the surrounding soil in the process. Instead, cutting the plant at the base and leaving the rest as is allows those roots to remain underground and gradually decompose.

As the roots break down, they become organic matter that can be incorporated into the soil by worms and microorganisms. Leaving roots behind also means less digging and disturbance. University of Minnesota Extension notes that plant roots, organic matter and soil microorganisms all play important roles in building and maintaining healthy soil structure. Minimizing soil disturbance can help preserve the structure that develops naturally underground.

A Simple Fall Garden Cleanup

The process really couldn’t be easier. Once your tomato plants are finished producing, simply cut the stems off near the soil surface. Remove the above-ground plant material and leave the root system underground to decompose naturally.

The same approach can work with many other garden crops. Instead of treating every harvest as a reason to completely clear the soil, gardeners can think of leaving roots in place as paying it forward towards next season’s crops.

There is one important exception: don’t leave the roots of plants that suffered from serious soilborne diseases. Diseases like as Fusarium can persist in soil, and experts recommend removing infected plants, including their roots, to help prevent disease from carrying over to future crops.

For healthy tomato plants, however, cutting rather than pulling can turn fall cleanup into one less chore while allowing the garden’s underground ecosystem to put those forgotten roots to work.
