WaterFor Mount Airy Fothergilla, ensure the soil is kept consistently moist but not waterlogged, especially during the first growing season to establish a deep root system. Watering should be done deeply once a week, providing about 1 gallon of water for each square yard of soil. During periods of drought or extreme heat, increase watering frequency to twice a week. In non-drought conditions, reduce watering to every other week once the plant is well-established. Adjust watering as needed during fall and winter when the plant is dormant, ensuring the soil does not become bone dry.
LightMount Airy Fothergilla thrives best in full sun to partial shade conditions. It should be planted in a spot where it receives at least six hours of direct sunlight daily, though it can tolerate some afternoon shade. The ideal location maximizes morning sunlight with some protection from intense late-day sun, especially in hotter regions.
TemperatureThe ideal temperature range for Mount Airy Fothergilla is between 60°F and 80°F. This plant is hardy and can tolerate temperatures down to about -10°F and withstand summers up to 90°F without much stress. However, prolonged exposure to extremes outside this range can damage the plant.
PruningMount Airy Fothergilla benefits from pruning to shape the plant, control its size, and remove any dead or damaged branches. The best time to prune is right after flowering in late spring to early summer, as the plant blooms on old wood. Annual light pruning is generally sufficient, but it can tolerate more extensive shaping every few years if necessary.
CleaningAs needed

Life cycleWitch Alder (Fothergilla × intermedia 'Mount Airy') begins its life cycle when the seeds germinate, often in spring to early summer, after experiencing a period of cold stratification which breaks their dormancy. The seedling stage follows, where the plant establishes roots and shoots, setting the foundation for future growth. As it enters the vegetative stage, Witch Alder develops leaves and branches, increasing in size and creating the bushy structure characteristic of mature shrubs. Upon reaching maturity, often in a few growing seasons, the plant produces distinctive white, brush-like flowers in early spring before the leaves emerge. After pollination, typically by bees and other insects attracted to its fragrant flowers, the plant develops small capsules that contain seeds ready for dispersal in late summer to fall. This shrub goes dormant in winter, shedding leaves to conserve resources, completing the annual cycle which can repeat for many years, given that Witch Alder is a deciduous shrub that can live for several decades.
PropogationPropogation time
Early spring
The most popular method of propagation for Fothergilla x intermedia 'Mount Airy', commonly known as Mount Airy dwarf fothergilla, is through softwood cuttings taken in late spring or early summer. At this time, the plant is actively growing, and the new stems are mature enough yet still pliable, making them ideal for rooting. A cutting should be about 3 to 6 inches long with several leaves, and the lower leaves should be removed. It's important to make a clean cut just below a set of leaves, and it's beneficial to dip the cut end in a rooting hormone before planting it in a well-draining soil mix. The cutting should then be placed in a bright area out of direct sunlight and kept consistently moist but not waterlogged. Maintaining high humidity around the cutting by covering it with a plastic bag or dome can further enhance the rooting process. After several weeks, the cutting should develop roots and can be transplanted to a more permanent location.
