Overwintering Habanero Indoors: Lights, Fertilizer & Watering

A San Antonio habanero bloomed prolifically after a cold snap moved it inside. To keep it productive through winter:

Light

• 10–12 hrs/day of full-spectrum LED or T5 fluorescent (6500 K).
• Position 6–12″ above canopy; use timer.

Fertilizer

• High-phosphorus water-soluble (e.g., 10-30-20) every 10 days.
• Stop high-N feeds—they promote leaves, not fruit.

Watering

• Deep soak when top 2″ dry; discard runoff.
• No saucer standing water—roots need oxygen.

Pruning & Pollination

• Trim leggy growth by ⅓ to keep compact.
• Hand-pollinate: flick flowers or use a small brush midday.

Reality Check

Peppers are perennials in tropics but grown as annuals in temperate zones. Indoor winter yields are modest (10–20 fruit). Many growers compost in fall and start fresh in spring for heavier crops.
