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

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.
