I didn't mean to hijack the original question, so I observed my tomatoes a bit and took some pictures to share...
Here is a pic of a tomato plant using pokeweed as a living support:
Here are some unsupported tomatoes growing at ground level:
You can't really see any of the tomatoes from a distance:
The closer you get, and red starts to show through:
They aren't completely on the ground, but they are within inches of the ground:
Found some
volunteer cherry tomatoes doing the same thing:
Here is about a quarter of the harvest so far:
I noticed something interesting, any tomatoes that were on trellises are still green:
More green ones on a
trellis:
Third and final trellis:
A few observations:
1. Pokeweed seems to work fine as a living tomato support.
2. Sunflowers didn't work for me as tomato supports.
3. The tomatoes rambling along the ground ripen faster that those on trellises.
4. My sample was small, and mostly just a grab bag of heirloom tomato plants I started this winter, stuck in the ground, and then ignored until harvest.
5. The tomatoes rambling near the ground were on smallish raised beds with some
wood buried in them - roughly 3 years old and lots of
polyculture.
