When to plant: May–June
- Sweet potatoes take 3–4 months to mature. Leave them in the ground until the roots are full grown and the vines begin to turn yellow.
- Handle carefully to prevent skinning and bruising.
- Sugars will increase in storage.
- Traditionally, sweet potatoes were 'cured' immediately after harvest. While not necessary, the process does promote longer lasting storage. Proper curing conditions are 85°F at 85% relative humidity for 4 to 7 days with ventilation.
- Sweet potatoes grow best in light, sandy soils.
- Once the vines spread to cover the ground, little weeding is required.
- Do not water during the last 3 to 4 weeks before harvest to protect the developing roots.
