Grow Potatoes from Scraps
Don't throw out that sprouted potato - plant it!
What to Plant
- • Whole sprouted potato: Plant it whole
- • Potato pieces: Cut with 1-2 eyes each
- • Potato peelings: With eyes attached (less reliable)
Step-by-Step Guide
Let Sprouts Develop
If your potato has small buds but no sprouts yet, place it in indirect light for 1-2 weeks. Wait for sprouts to be 1/2 to 1 inch long.
Cut & Cure (Optional)
For large potatoes, cut into pieces with 1-2 eyes each. Let cut surfaces dry for 24-48 hours to prevent rot. Small potatoes can be planted whole.
Prepare Container
Fill a 10-15 gallon container 1/3 full with potting mix. Grow bags are excellent. Ensure drainage holes - potatoes hate waterlogging.
Plant & Hill
Place potato pieces 4 inches deep, sprouts facing up. As plants grow 6+ inches, cover with more soil ("hilling") to encourage more tubers. Leave top leaves exposed.
Harvest
New potatoes: harvest when plants flower (small, tender). Full harvest: when foliage dies back (~3-4 months). Dump container and collect your bounty!
Hilling: The Key to More Potatoes
Potatoes form along buried stems. The more stem you bury, the more potatoes you get!
- • When: Add soil when plants are 6-8 inches tall
- • How much: Cover stems leaving only top 4-6 inches of leaves exposed
- • Repeat: Hill 2-3 times as plants grow
- • Why: Buried stems produce more tubers; exposed tubers turn green and toxic
Frequently Asked Questions
Can I plant a sprouted potato from the pantry?
Yes! Sprouted potatoes are ready to plant. The sprouts are growth points. For best results, cut potato into pieces with 1-2 sprouts each. Let cut surfaces dry for 24 hours before planting.
Are grocery store potatoes safe to plant?
They'll grow, but may carry disease. Grocery potatoes are also sometimes treated to prevent sprouting. Certified seed potatoes from nurseries are guaranteed disease-free and untreated.
How many potatoes will I get from one plant?
Expect 5-10 potatoes per plant in containers, potentially more in ground gardens. Yields depend on variety, container size, and growing conditions. Larger containers = more potatoes.
Can I grow potatoes in a bucket or bag?
Absolutely! Use at least 10-gallon containers. Grow bags are excellent - they're breathable and easy to harvest. You can also use 5-gallon buckets but yields will be smaller.
