mountain ash

Mountain ash should be watered regularly, with the amount depending on the season. During the warmer summer months, mountain ash should be watered once per week, supplying a thorough soaking and allowing the soil to dry out slightly before next watering. During the cooler months of fall and winter, mountain ash should be watered more sparingly, about 1 per 2 weeks, supplying a light drink of water. During winter dormancy, mountain ash should be watered only when the soil is completely dry.

Mountain ash (Sorbus alnifolia) grows best in full sun, meaning at least 6-8 hours of direct sunlight per day in order to thrive. When planting mountain ash in the spring, make sure to select a location where it will receive ample sunlight throughout the growing season. Remember that the sun will move from east to west throughout the day, so it is important to keep the changing sunlight in mind when choosing the location for your mountain ash. Additionally, be aware that during the summer months, the sun will be at its strongest and your mountain ash may need some shade to provide additional protection during midday hours.

Mountain ash can be pruned in late winter or early spring before the growing season starts, when the plant is still dormant. Prune away any dead, diseased or damaged branches, and remove any stems growing in an awkward or unbalanced direction. The plant can also be cut back to control the overall size and shape. Heavy pruning and shaping is usually not needed, and should not be done in 1 session but carried out in stages over several years. Each time, take away only a quarter to a third of the previous season’s growth.
