High Temperatures Impact Tomato and Pepper Flowering in 2026
US · Published Aug 14, 2026
Reports indicate ongoing issues with flowering and fruiting in tomatoes and peppers, particularly in high tunnels and field settings.
High temperatures exceeding 85°F (29°C), which have been more frequent this season, are causing flower abortion.

Impact & Risks

Farmers growing tomatoes and peppers in high tunnels or fields are at risk of reduced yields due to flower abortion caused by high temperatures. Poor flowering can also result from nutritional imbalances, potentially leading to economic losses. The presence of bacterial pathogens, exacerbated by environmental conditions like high humidity and wet foliage, poses an additional risk to crop health and productivity. Without proper management, these issues could significantly impact the agricultural output of affected regions.
