Watering a Heuchera 'Caramel'
The Heuchera 'Caramel' thrives best with consistent moisture, which supports its vibrant foliage and delicate flower production. Although it is drought-resistant, maintaining an average watering schedule will enhance the plant's health and aesthetic appeal. During the active growing season, ensure the soil remains well-drained yet moist, particularly when situated in sunnier spots. In periods of high heat or extended dry spells, increase watering frequency to prevent stress. Conversely, less frequent watering is necessary during cooler, overcast days to avoid waterlogging, which the alum root tolerates poorly.
