What You Need to Regrow Lettuce from Lettuce

Lettuce Base
- The leftover stump or core of a lettuce head, cut approximately 2–3cm above the base.
Shallow Dish or Bowl
- Use a container that can hold water and support the lettuce base.
Water
- Fresh, clean water for keeping the base hydrated.
Sunny Spot
- A location with bright, indirect sunlight, such as a windowsill or countertop.

How to Regrow Lettuce from Lettuce: Step-by-Step

1. Prepare the Lettuce Base

Cut the base of the lettuce head approximately 2–3cm from the bottom.
Ensure the base is clean and free from decayed or damaged leaves.

2. Place the Base in Water

Fill a shallow dish with about 1–2cm of water.
Place the lettuce base cut-side up in the dish, ensuring the bottom is submerged.

3. Choose the Right Location

Place the dish in a sunny spot with bright, indirect sunlight for 6–8 hours daily.

4. Monitor and Change the Water

Change the water every 1–2 days to prevent mold or bacteria growth.
Keep the base hydrated, but do not fully submerge it.

5. Watch for New Growth

After 3–5 days, you’ll notice small leaves sprouting from the center of the base.
Roots may also begin to form at the bottom.

6. Transfer to Soil (Optional)

Once the leaves reach 5–7cm in height, transplant the lettuce base into a pot or garden bed.
Bury the base in well-draining soil, leaving the new growth exposed.
Water regularly to keep the soil moist.

Caring for Regrown Lettuce

Watering
- Keep the soil or water source consistently moist but not waterlogged.
Light
- Ensure the plant receives 4–6 hours of sunlight daily. For indoor growing, use grow lights if natural light is insufficient.
Fertilizing
- Feed the lettuce with a diluted liquid fertilizer every 2–3 weeks to encourage healthy growth.
Pruning
- Remove any yellow or damaged leaves to promote fresh growth.
Preventing Mold
- Change the water regularly and avoid overcrowding multiple lettuce bases in one dish.

Harvesting Regrown Lettuce

When to Harvest
- Regrown lettuce is ready to harvest in 10–14 days when the leaves are 5–10cm tall.
How to Harvest
- Snip the outer leaves first, leaving the inner growth intact for continuous regrowth.
Repeat the Process
- Lettuce bases can regrow multiple times, although each cycle may produce smaller leaves.

Common Problems and Solutions

Slow Growth
- Cause: Insufficient light or water.
- Solution: Ensure the base receives adequate sunlight and maintain consistent hydration.
Rotting Base
- Cause: Stagnant water or full submersion.
- Solution: Change the water regularly and avoid fully submerging the base.
Yellow Leaves
- Cause: Overwatering or lack of nutrients.
- Solution: Reduce watering frequency and consider using a diluted liquid fertilizer.
No New Growth
- Cause: Old or damaged lettuce base.
- Solution: Start with a fresh, healthy lettuce base.

Tips for Regrowing Lettuce Successfully

Use Fresh Lettuce Bases
- Older, decayed bases are less likely to regrow effectively.
Provide Adequate Light

- Grow several lettuce bases simultaneously for a continuous supply of fresh greens.
Transplant for Larger Yields
- Moving the regrown lettuce to soil will produce more robust leaves.
Harvest Early
