Tomato Blossom Drop in Wet Weather: Hybrid Stress?

Rain-Induced Drop

Heavy rain + humidity = pollen clumping, poor pollination, fungal pressure. Flowers drop naturally.

Hybrid Vigor Concerns

Many gardeners report odd behavior in modern hybrids—sterile pollen, weak roots, nutrient sensitivity. Open-pollinated/heirloom often more resilient.

Actions

• Shake plants gently midday (pollen release).
• Improve airflow (prune, stake).
• Copper spray preventatively.
• Consider heirlooms next year.
