Harvest Tips
Harvest fruits when 8-10 inches long and deep purple with a glossy finish, typically 70-85 days after transplanting. Use sharp pruning shears or a knife to avoid damaging the plant. Fruits can be harvested at any size but are most tender when medium-sized. Pick regularly to encourage continuous production throughout the season. Best flavor comes from fruits harvested in early morning.
