Q.Should I Trim Tomato Plants At The Bottom?

Zone Evanston, IL 60202 | Anonymous added on September 18, 2026 | Answered

In your 9/17 newsletter you had a picture in the article how to get more yield from tomatoes this fall – the tomato plants were bare of leaves at that looked like 3/4 of the way up. Should I be doing that now, even if there are tomatoes on the vines, like in the picture?

Trimming off the lower foliage can help prevent foliar diseases and can be started right away in the spring. You can trim off the lower foliage now if desired. (I think it is a little high in the photo. Leaves shade the fruit and supply sugar.) Here is more:
