I believe they would become roots if you planted deeper.

Tomatoes like being transplanted a couple times from seedlings
up to final planting.
Just that more roots mean more nutrients up top, no?

I just got back looking at tomato plants at a garden center. Most of them
had little hard white downward pointing conical spikes growing in the lower
part of the stems. Further up the stem were were raised mounds of green
tissue that looked like they had not erupted yet. Does anybody know what
the spikes are and if they mean trouble or are pretty much natural? Some
of the varieties I looked that had spikes were Sun Gold, Better Boy, and
something with 3 letters followed by 444, i.e. --- 444.

Thanks for any help,
