Water deeply and regularly. Apply mulch to retain moisture. Feed with potassium-rich fertilizer every 2-3 weeks. Thin excess fruit if desired for larger peppers.

Harvest Tips
Harvest peppers green for tender flavor or allow to fully ripen to red for maximum sweetness and nutrition (about 2-3 additional weeks on plant). Cut peppers with scissors or pruners rather than pulling to avoid damaging branches. Pick regularly to promote continued flowering and fruiting. Fruits are ready when they reach 4-5 inches long and feel firm.
Fun Facts
- 🌱 Big Heart peppers are named for their distinctive heart-shaped silhouette when viewed from above, making them visually distinctive in the garden and kitchen.
- 🌱 Unlike hot peppers, sweet bell peppers like Big Heart lack capsaicin (the compound that makes chili peppers spicy) due to a recessive gene, making them universally palatable.
- 🌱 Peppers are actually fruits botanically, not vegetables—they develop from the flower's ovary and contain seeds, though culinary usage classifies them as vegetables.
