Growing Giant Marconi — the things that trip people up
- You can pick it green (unripe) for a milder, crisper pepper, or leave it on the plant to ripen to full color and sweetness — your call.
- Peppers love warmth. Don’t rush transplants into cold soil — they sulk below about 55°F. Wait for warm nights, and they take off.
