Growth Stages

1

Establishment

3-4 weeks

Young plant develops initial root system and first true leaves emerge; foliage begins showing copper tones.

Keep soil warm (70-75°F), maintain high humidity, provide bright indirect light, avoid transplant shock by acclimating gradually.

2

Vegetative Growth

6-10 weeks

Plant produces new obovate leaves in rapid succession; copper and bronze coloration intensifies; stems elongate and branch.

Pinch growing tips every 2-3 weeks to encourage bushier growth, fertilize bi-weekly with balanced fertilizer, maintain consistent moisture and warmth.

3

Foliage Maturation

4-8 weeks

Plant reaches full height with dense, bushy canopy; leaf color peaks with rich copper-red iridescence; metallic sheen becomes pronounced.

Continue pinching to maintain shape, deadhead tiny inconspicuous flowers if desired, reduce fertilizer slightly, monitor for pests in warm conditions.

4

Maintenance/Maturity

Ongoing

Fully developed shrub maintains vibrant foliage color year-round in warm climates; minimal new growth in cooler seasons or when day-length decreases.

Prune in early spring to maintain size and shape, fertilize monthly during growing season, reduce watering and feeding in dormant season, protect from cold.

Harvest Tips
