Mahonias are grown for their attractive foliage and fragrant, showy winter flowers. They provide an invaluable source of pollen and nectar for winter colonies of bumblebees and other pollinators.
Mahoniajaponica bears racemes of lemon-yellow flowers from late autumn to early spring with a sweet lily-of-the-valley fragrance. It has received the coveted RHS Award of Garden Merit.
How to grow Mahonia japonica
For best results, grow Mahonia japonica in fertile, moist but well-drained soil in partial or full shade. It is suitable for a wide variety of planting positions, including slopes and banks.
Mahonia japonica originates from Taiwan. Although some mahonias are listed as invasive species in areas such as the southeastern United States, Mahonia japonica is not considered invasive in the UK.
How to care for Mahonia japonica
Mahonia japonica requires little attention once it has become established. Plants are generally problem-free but it is worth checking regularly for rust and powdery mildew. Mulch around the base of plants in early autumn to reduce weed cover and protect the roots from cold weather in the winter.
Plants should be pruned, if needed, in spring after flowering. Prune back old stems that are bare at the base to strong low growth. Cut out any damaged, diseased or dead material. Neglected plants will usually respond well to hard pruning and stems should be cut back to around 15cm from the ground. Wear gloves and other protective equipment when pruning.
