🌾 Seed Saving Guide

🪴 Vegetative propagation

Propagate vegetatively, not by seed

Sweet potatoes are propagated from "slips" — sprouts grown from a stored tuber, not from seed in typical gardens.

Store tubers at 55–60°F in a humid spot. In spring, place in shallow water to grow slips for planting.
