Apply balanced slow-release fertilizer in spring; prune lightly to shape; maintain consistent moisture
Flowering

Harvest Tips
Cut branches for holiday arrangements in winter when berries are vibrant and foliage is deepest bronze. Cut just above a bud at 45° angle. Holly can be lightly pruned annually in late winter (February-March) to maintain shape; avoid heavy pruning that reduces berry-bearing wood.
Fun Facts
- 🌱 Bronzefolia Holly's bronze coloration is a natural cold-hardiness response; the pigmentation deepens significantly when temperatures drop below 40°F, making it increasingly ornamental as winter approaches.
- 🌱 Holly berries are toxic to humans and can cause gastrointestinal upset if ingested, but birds are immune to the toxins and can safely consume large quantities; only female plants produce berries and require a male pollinator within 30-50 feet.
- 🌱 The name 'Ilex' comes from the Latin word for holly and was adopted by Linnaeus; this genus has over 600 species distributed across temperate and tropical regions worldwide, making it one of the most diverse ornamental shrub groups.
