Tomato Plants Flowering but Not Fruiting: Pollination and Nutrition

Coastal vs. Inland Disparity

Your 6-ft tall, flower-only plants (coastal, auto-watered nightly) vs. girlfriend's fruiting 3-ft plants (inland, less water) suggests:

Overwatering: Nightly 5-min cycles = shallow roots, nutrient leaching, poor pollination (pollen clumps in humidity).
Excess nitrogen: Lush growth, no fruit.
Poor pollination: No wind/insects in sheltered coastal spot.

Hornworms/cutworms feed day/night. Check at dusk with UV light (they fluoresce). Bt spray weekly.

Withholding water stresses plants—consistent moisture is better. Reduce frequency, increase depth.
