You might also take the dug up tomato and pot it in a 5 gallon or more
pot with commercial potting soil, and see if that improves its growth.

I'd give that dug-up tomato some shade for at least a week. You may
damage the root hairs while inspecting it and reduce its' ability to
suck up the water it needs. Even a deck chair on the south side of the
plant, would probably do.

Sunlight is important, so people tell me. I'm kinda sunlight challenged
myself having only 6 full hours of Sun in the best spots in my garden.
One spot, down the hill only gets 3 hr. to 4 hr. of sunshine and a
couple of "Juliets" volunteered for me. Not a big crop but still, it was
somethin'. This year I'm experimenting with an early, min-, and late
heirloom there just to know the potential for the spot.
