Dallas summers can push temperatures where tomato pollen fails even while plants look green and smug. That is not you “killing the vibe.” That is plant physiology. Strategy one: plant early enough to bank fruit before peak heat. Strategy two: choose heat-set / heat-tolerant cultivars for summer carry. Strategy three: mulch, even water, optional afternoon shade cloth—stress management, not fertilizer cosplay.
Cherries often keep producing when large slicers nap. Jalapeños will still show up to work. If your only tomato plan is a late May heirloom beefsteak and hope, the sidewalk already knows the ending.
Exam takeaway
Genetics + timing + water beat wishful watering of flowers that can’t set. Read the tomato module.
