Holly is a tough evergreen shrub or small tree that grows well in many conditions. It prefers well-drained soil and can tolerate both sun and shade. It needs occasional watering, especially in dry periods, and benefits from pruning to maintain shape. Holly is generally low-maintenance but can be sensitive to overwatering or poor drainage.

Holly (Ilex aquifolium) can cause mild allergic reactions in some people, especially from its pollen and contact with its leaves or sap. People sensitive to plant pollen or with sensitive skin should handle it carefully. Wearing gloves when pruning and avoiding inhaling pollen during flowering can help reduce exposure.
Common problems
Overwatering can cause root rot, and poor drainage may lead to leaf yellowing. Pests like scale insects or spider mites can occasionally appear. Lack of sunlight may reduce berry production.
Uses
Used mainly as an ornamental plant for hedges, garden decoration, and holiday displays due to its attractive leaves and berries.
Notes
Prune holly after flowering to shape the plant and encourage berry production. Be cautious of the sharp leaf edges when handling. Holly can be grown indoors in bright light but thrives better outdoors.
