Can I grow sweet potatoes from organic store bought ones and reap sweet potatoes?
Yes, you can grow sweet potatoes from organic store-bought ones and successfully harvest sweet potatoes, as long as they are untreated with sprout inhibitors. Here’s a step-by-step guide:
Organic sweet potatoes are typically untreated, making them ideal for planting. Avoid conventionally grown ones unless labeled "non-treated."
Choose a Healthy Sweet Potato: Look for one that’s firm and free of mold or soft spots.
Cut or Submerge in Water:
Cut the sweet potato in half and place it cut-side down in a shallow container of water, or
Suspend the whole sweet potato in water using toothpicks (half submerged).
Provide Warmth and Light:
Place the container in a warm spot with indirect sunlight (70°F–80°F).
Wait for Slips to Sprout:
In 2–4 weeks, sprouts (called slips) will grow from the sweet potato.
Gently twist or cut slips off the sweet potato when they are 4–6 inches long.
Place slips in water so they develop roots.
Change the water every few days to keep it fresh.
Roots will form within 1–2 weeks.
Prepare the Soil:
Choose loose, well-draining soil rich in organic matter.
Ensure the location receives full sunlight.
Plant the Slips:
Space slips 12–18 inches apart in rows 3 feet apart.
Bury slips up to their first leaves.
Water Well:
Water immediately after planting and consistently during the first few weeks to help establish roots.
Watering: Regular but not excessive watering. Sweet potatoes are drought-tolerant once established.
Weeding: Remove weeds to reduce competition.
Fertilizing: Use a low-nitrogen, high-potassium fertilizer for better tuber growth.
Timing: Sweet potatoes are ready to harvest about 90–120 days after planting.
Sign of Maturity: Yellowing leaves or vines beginning to die back.
Method: Gently dig around the base to avoid damaging the tubers.
Cure sweet potatoes in a warm, humid area (80°F and 85% humidity) for 7–10 days.
Store in a cool, dry place (55°F–60°F) for long-term use.
Enjoy your homegrown sweet potatoes!
If your sweet potato plant produced a lot of roots but no tubers, several factors might have caused the issue. Here's a breakdown of potential reasons and how to prevent it.
Cause: Sweet potatoes need ample room for their roots to expand and form tubers. A small or crowded container can lead to root binding and no tuber development.
Solution:
Use a container at least 12–18 inches deep and 20 gallons in volume for adequate space.
For in-ground planting, ensure loose, well-draining soil with enough room for roots to spread.
Cause: Dense or compacted soil can restrict root expansion, preventing tuber formation.
Solution:
Use light, sandy, or loamy soil mixed with compost. Avoid heavy clay soil or soil with too much organic matter, as this can encourage foliage over tubers.
Cause: High nitrogen levels encourage leafy growth at the expense of tubers.
Solution:
Use a balanced fertilizer or one lower in nitrogen and higher in potassium (e.g., 5-10-10).
Fertilize lightly after planting and avoid overfeeding.
Cause: Sweet potatoes need 90–120 days of warm temperatures to form tubers.
Solution:
Ensure you plant early in the season or use a longer growing variety.
In cooler climates, start slips indoors and transplant when temperatures are consistently warm.
Cause: Irregular watering can stress the plant and hinder tuber development.
Solution:
Water regularly but avoid overwatering. Sweet potatoes prefer even moisture but dislike soggy soil.
Cause: Sweet potatoes need at least 6–8 hours of direct sunlight daily for healthy tuber growth.
Solution:
Ensure your growing location gets full sun. If using a container, move it to the sunniest spot available.
Reevaluate your container size or soil type for future plantings.
Try growing slips in a new area or mix with looser soil.
Monitor watering, sunlight, and nutrients carefully.
With these adjustments, you’re likely to see better results in your next sweet potato harvest!
