Regrow Lettuce from Scraps
Turn that lettuce base into free salad greens
Set Realistic Expectations
Regrown lettuce won't produce a full head. You'll get small leaves for garnish or sandwiches. For full salads, grow lettuce from seed - it's easy and fast!
Step-by-Step Guide
Save the Base
Cut lettuce leaving 2-3 inches of the base with the root end intact. Romaine and butterhead work best.
Place in Shallow Water
Put base in a shallow dish with 1/2 inch of water. Don't submerge - just enough to cover the bottom. Use a wide, shallow container.
Provide Light & Change Water
Place on a sunny windowsill. Change water daily to prevent rot. Keep cool if possible - lettuce prefers 60-70°F.
Watch for New Growth
New leaves will sprout from the center in 3-5 days. Growth may be slow but steady over 2-3 weeks.
Optional: Transplant to Soil
Once roots develop, transplant to soil for better growth. In water alone, the lettuce will eventually exhaust its energy reserves.
Tips for Success
Fresh is Best
Use fresh lettuce bases immediately. Older, wilted bases are less likely to regrow successfully.
Keep it Cool
Lettuce prefers cool temperatures. Hot windowsills cause bolting (flowering) and bitter leaves.
Daily Water Changes
Stagnant water leads to rot. Change water every day for best results.
Transplant for More
Water-grown lettuce has limited nutrients. Transplant to soil for larger harvests.
Frequently Asked Questions
Which lettuce types regrow best?
Romaine works best, followed by butterhead/bibb lettuce. Loose leaf varieties regrow but produce fewer leaves. Iceberg rarely works well - the base rots before regrowing.
Will regrown lettuce taste the same?
Regrown lettuce may be slightly more bitter, especially if it starts to bolt. The leaves will also be smaller than store-bought. For best results, transplant to soil after rooting.
How much lettuce will regrow?
Don't expect a full head! You'll get a small amount of leaves - enough for a garnish or addition to a sandwich, not a full salad. For more lettuce, grow from seed.
Why is my lettuce base rotting instead of growing?
Too much water! The base should sit in shallow water (1/2 inch), not submerged. Change water daily and ensure good light. Warm temperatures speed rot - keep below 75°F.
