Tamarillo
Solanum betaceum
Zones 8–13
Growing
Tamarillos are sensitive to frost and grow best in subtropical environments where temperatures remain stable. In a region with more pronounced seasons, expect the harvest in autumn. When planting, consider a denser arrangement to shield the woody shrubs from wind damage, and use soil that is light, deep, and permeable to prevent waterlogging.
These plants are more resistant to pests than common garden tomatoes, but watch for Solanaceae-related issues. The lateral branches can become fragile when heavy with fruit. To prevent branches from snapping under the weight, harvest the fruit as soon as it reaches maturity.
The fruit does not all ripen at once, so you will need to make several separate trips to the tree. The fruit continues to ripen after picking, and you can store it at room temperature for up to 20 days. Keep the fruit unwashed until you are ready to eat it.
