black elder

Black Elder (Sambucus nigra 'Witches Broom') should be watered fairly often and deeply. During the spring and summer months, when it is actively growing, you should water the plant deeply once per week, ensuring it is given enough water so that it penetrates at least 8 inches into the soil. During the fall and winter months, when growth is minimal or non-existent, only water once every 2 weeks. Make sure never to overwater the plant, as excess water can cause root rot.

Black elder (Sambucus nigra 'Witches Broom') needs at least 6 hours of direct sunlight each day to thrive. These plants prefer full sun in the cool of the morning, but can tolerate partial shade in the afternoon when temperatures are higher. They can tolerate more shade in the summer months when temperatures are highest. During the winter months, these plants may require more shade and will require a freeze period of 3-4 weeks in temperatures below 26-27°Farenheit (-3 to -2 degrees Celsius).

Black elder (Sambucus nigra 'Witches Broom') should be pruned selectively during the spring and summer, at least once in the planted year to reduce its size. It should be pruned back a few feet to keep it within the desired size and growth habit. To keep a clean, healthy overall appearance, it should also be lightly pruned and deadheaded in the summer. It may be necessary to do more extensive clipping back to keep it within bounds.
