What Is the Ideal Temperature Range for hortensia?

Bigleaf hydrangea showcases notable resilience to temperature variations, handling cold down to -15℃ (5℉) and heat up to 38℃ (100℉). Despite this adaptability, protective measures during extremes are vital for optimal health. In cold, symptoms like wilting or frost damage may appear, while overheating can cause leaf scorch or browning. Countermeasures include mulching and frost covers for cold, and afternoon shade or increased watering for heat. This tolerance range makes bigleaf hydrangea suitable for various environments, but attentiveness to weather-induced stress is crucial for thriving growth.
