Choosing varieties for Texas heat

Most tomato failures in Texas start at the seed rack. Big beefsteak types stop setting fruit once nights stay above 75°F, which in DFW means anything you plant late simply stalls through summer.

Lean on heat-tolerant, determinate and short-season varieties: Celebrity, Phoenix, Solar Fire, and the cherry workhorse Sungold. Plant a second wave in mid-July for a fall crop once the worst heat breaks.

Determinate plants set most of their fruit in a tight window — perfect for a single big canning weekend. Indeterminate types trickle fruit until frost, better for fresh eating.

Key takeaways

  • ✓ Choose heat-set varieties (Celebrity, Solar Fire, Sungold)
  • ✓ Plant a second wave mid-July for fall
  • ✓ Determinate = one big harvest; indeterminate = steady trickle
