Why are my dahlias dying in the summer heat in a warm climate?

Question

ForwardPlant Team · Accepted Answer

Dahlias struggle in intense summer heat because they prefer cooler, more temperate conditions. High temperatures stress the plants, leading to wilting, scorching, and eventual decline. Their roots struggle to absorb sufficient water to counteract the increased transpiration, and metabolic processes are negatively impacted. Providing afternoon shade and consistent moisture can mitigate some of these effects.
