What Is the Ideal Temperature Range for weigelia?
Old fashioned weigela is known for its significant resilience to temperature variations. It can endure cold temperatures as low as -25℃ (-13℉) and heat up to 38℃ (100℉). This high tolerance allows it to thrive in a variety of climates, though it may require protection during extreme cold or heat. Under cold stress, old fashioned weigela might exhibit leaf drop, slowed growth, or branch dieback. Conversely, in extreme heat, wilting, leaf scorch, or drought stress can occur. To combat these issues, mulch can insulate roots in cold weather, while adequate watering and partial shade help mitigate heat stress. Proper care enhances old fashioned weigela's longevity and aesthetic appeal.
