Light: Full sun (6+hrs/day) to part sun (4-6 hrs/day); can grow in shadier spots but will flower far less and fall foliage will be dull
Soil: Aronia tolerates any soil, including extremes of pH, moisture, and dryness
Water: Average water needs; drought tolerant once established
Fertilizing: Nothing special required; apply a granular fertilizer formulated for woody plants in early spring if desired
Pruning: Aronia blooms on old wood, so if pruning is required, it should be pruned immediately after flowering. Do note, however, that this will remove the potential for fruit to form. If you need to manage the spread of the plant, that can be done as needed.
Other notes: Deer do not severely damage aronia plants like they do arborvitae or hosta. However, they (and rabbits, especially for low-growing varieties) may eat the flower buds or flowers, which in turn prevents fruit from forming. While its durability and fall color are still enough reason to grow it, those with deer in their area should have reasonable expectations of what may happen.
