How To Plant and Grow Sweet Potatoes from Slips

Slips are rooted sprouts that have grown from a mature sweet potato. It is normal for slips to appear wilted and dry due to the conditions during transit. Don’t worry, they will perk back up. A few yellowing leaves are also normal, you can remove these before planting.

Receiving
• Remove wax paper and moss from the base of your slips.
• Transplanting your slips within 24 hours of receipt is the most ideal.
• Transplanting near sundown is recommended to avoid immediate exposure to hot mid-day sun.
• If weather or other conditions prevent immediate transplanting, there are two options for storing your plants:

a. Trim your roots by about 1 centimeter with sterilized scissors. Place roots in a vase with a small amount of cool water. Water should only cover the white section of the roots. Do no submerge green portion of slip. Store at room temperature in indirect sunlight for 3-4 days. Do not store in a refrigerator.

b. Trim your roots by about 1 centimeter with sterilized scissors. Plant roots in bunches of 3-4 into a pot with moistened potting mix. Plant slips at the level where the white root transitions to green. Store at room temperature in indirect sunlight for 3-4 days. Do not store in a refrigerator.

Soil Preparation
Sweet Potatoes grow best in loose, well drained soil with high organic matter. Add a fertilizer of 8-20-30 as needed, prior to planting. Black plastic can be used in northern areas to help warm the soil, as sweet potatoes prefer a soil temperature of 70°F or higher.

Planting
Create ridged rows 3' feet apart and set plants at 12" spacing within rows. Plant slips so that white part of the root is fully covered. Transplanting near sundown is preferable to avoid exposure to mid day sun. Water well after planting.

Watering
Consistent soil moisture produces the best results. Irrigate if soil becomes too dry.

Harvest and Storage
Dig sweet potatoes when they have reached desirable size, being careful not to wound or bruise them. Dry the sweet potatoes thoroughly and store at 55°-60°F in a well ventilated, dark spot.
