Q: My grape tomato vine is fourteen-plus feet tall. Is this normal? I’m risking my life to climb on the roof where I have attached them to pick the ones at the top.

A: Now you know what an “indeterminate” tomato variety does: it grows until frost. “Determinate” tomatoes grow until they set a big crop of fruit and then they die. The cherry tomato ‘Sweet 100’ is well known for its astonishing vine length. If any tomato is suited for a head-high arbor, this is the one.
