Soon my tomato harvest is done and I wonder whether I can leave the roots in the ground for rotting or whether I should get them out.
I heard that for some other annuals leaving the root in the ground as adding nitrogen to it. Does this apply to tomatoes as well?
Are there any risks? Are there any benefits?
UPDATE: Thanks to a comment I forgot to mention that I assume that the roots won't survive my -10 °C winter.
