# Growing Sweet Potatoes Indoors in the Winter
Sweet potatoes hail from South and Central America and grow as tropical plants with specific sun and temperature requirements. These summertime plants won't grow in the outdoor garden in winter, but thrive with indoor starts at that time. Start the sweet potato in a glass of water situated in a sunny window sill for early rooting, then transplant the vines outside when frost lifts.

1
Start sweet potatoes indoors six to eight weeks before average last frost in your area. These plants require 100 to 110 days of frost-free growing, and do well with early starts for a longer season.
-
2
Push five to six long toothpicks into the middle to top one-third of the sweet potato, angled outward. These provide your supports for growing.
-
3
Fill a large glass or jar with water. Stick the pointed end of the sweet potato in the water and leave the toothpicks resting on the rim. The top one-half or one-third of the sweet potato should stick up out of the jar or glass.

Put the jar in a warm, sunny location for rooting. Mix water-soluble 10-10-10 fertilizer into the water for potato nutrition and maintain an adequate water level until transplant.
