Harvest Tips
Harvest when fruits are firm but yield slightly to pressure (firm-ripe stage) in August-September. Twist gently and lift fruits upward; handle carefully as they bruise easily. For peak sweetness, harvest when ground color turns from green to light yellow-green. Fruits do not ripen significantly after picking but will soften slightly in storage.
