PLANTING STEP BY STEP
- WHEN YOU RECEIVE YOUR SLIPS PUT THEM IN WATER! FILL GLASS OR CUP, PUT THE ROOTS IN IT!
- Dig a trench for each row. 12-18 inches wide, 6-12 inches deep. Rows 30-36 inches apart.
- Break up and mix soil dug from trench with compost and/or loose soil. It is important the soil is loose!
- Lay slips in trench 12-18 inches apart.
- Cover slips with soil dug and mixed from trench. Do NOT fully cover but some leaves can be covered.
- Slips should be 6-10 inches deep. Again NEVER fully cover the slips, some leaves should be above soil.
- Rows should look like a “hill” in the middle. This allows water to drain off to the sides and not pond in rows.
- OPTIONAL: Side dress rows with compost.
- Water rows well to help get plants started.
- Side dress rows with compost about 4 weeks after planting. An organic fertilizer can be used as substitute.
- Weed rows well. Do NOT prune vines.
- Water plants when hot and dry. Stop extra watering 3 weeks before harvest.
- Tip: Any vine covered in soil will root and grow more potatoes. You might be surprised with how many you get!

HARVEST, CURING, & STORAGE
- Harvest sweet potatoes just before first fall frost in cold areas. Warm areas harvest late fall, watch for dying leaves.
- Use fork or shovel at side of rows to loosen soil. Grab plants at base and pull. Check Below for any additional tubers.
- Let potatoes lay in sun for 1-3 days. (no rain) Carefully remove any clumps of dry dirt. DO NOT CLEAN.
- CURING: Cure potatoes for 20-45 days at high temperature. 75-90 degrees Fahrenheit, 50% or less humidity.
- Curing will bring out the sweetness in the potato and increase storage time.
- Once cured store at room temperature 60-75 degrees Fahrenheit. Plenty of air flow.
- DO NOT WASH/CLEAN POTATOES UNTIL READY TO USE. THE DIRT HELPS! :)
