A bag of organic salad greens costs $5 and lasts a week. A packet of mixed lettuce seeds costs $2 — and can feed your family salads for two months. Here’s exactly how to turn one into the other, on a windowsill or balcony.
Estimated reading time: 6 minutes.
Why this works
Lettuce and other salad greens are “cut-and-come-again” crops — you snip the outer leaves and the plant regrows new ones in 7–10 days. One little seed becomes weeks of harvests.
What you need
- A shallow container at least 6 inches deep with drainage holes.
- Quality potting mix (not garden soil).
- One $2 packet of mixed leaf lettuce or “mesclun” seeds.
- A sunny spot — 4–6 hours of direct light is enough.
Step-by-step planting
Day 1: sowing
- Fill the container with damp potting mix to 1 inch from the rim.
- Sprinkle seeds evenly — don’t worry about spacing yet.
- Cover lightly with 1/4 inch of soil and mist the surface.
- Place in bright light. Keep moist but not soggy.
Day 7-10: thin and wait
- When seedlings have two true leaves, snip the smallest ones with scissors so plants stand 1–2 inches apart.
- Add a tablespoon of compost on top.
Day 25-30: first harvest
- Cut outer leaves with scissors, leaving the center 1.5 inches tall.
- The plant regrows for the next round.
- Harvest in the morning for the crispest leaves.
How to keep harvests coming
- Sow a new pinch of seeds every 2 weeks (called “succession sowing”).
- Move pots to cooler shade in summer — heat makes lettuce bitter.
- Liquid feed every 3 weeks for thicker leaves.
The math
- Seed packet: $2.
- One container can yield 4–6 ounces of greens per week for 6+ weeks.
- That’s roughly 2 pounds of greens, worth ~$50 at organic-store prices.
Practical tips
- Try a “cocktail” mix: leaf lettuce, arugula, mizuna, and spinach in one pot.
- Shade cloth or part-day shade extends summer harvests by weeks.
- Fall is the easiest season — cool weather equals slow bolting and sweet leaves.
- Keep seed packets in a cool, dry place; most stay viable 2–3 years.
Conclusion
One $2 packet, one container, and 30 minutes of work over a month — that’s your salad bar. Once you taste a leaf 10 minutes after harvest, the supermarket bag goes in the bin. Want to scale up? See our best container vegetables guide.
