How Many Lettuce Plants Per Person?
Lettuce is the crop where the count matters less than the timing. Plant 30 heads at once and they all mature the same week, so you eat salad for 10 days and then have none. The real answer is to sow a small batch every 2 weeks. Plan on about 4 to 6 plants per person in the ground at any time. Here is how to keep salad on the table for months, not days.

The short answer
Lettuce does not store, so you grow it in small, staggered batches. Sized per person, in the ground at one time:
- Salad a few times a week: about 4 leaf lettuce plants per person.
- Salad most nights: 6 or more per person.
- The real rule: sow a small batch every 2 weeks, do not plant a season's worth at once.
- For a family of 4 eating salad often: sow about 8 to 12 plants every 2 weeks.
Why succession beats a big planting
Leaf lettuce matures in about 45 days and a single sowing is ready all in one window. Plant 24 heads at once and they bolt together, so you get a glut and then a gap. This is the most common lettuce mistake.
The fix is succession: sow a small batch, then sow another every 10 to 14 days. Each batch comes ready as the last one finishes, so you have steady salad for months instead of one big pile. That is why the count is per planting, not for the whole season.
Cut-and-come-again stretches each plant
Leaf lettuce does not have to be a one-shot harvest. Pick the outer leaves and leave the center, and one plant keeps feeding you for weeks. That stretches a small planting further than pulling whole heads.
One leaf lettuce plant gives about 0.4 pound, or roughly 2 salad servings if you take the whole thing. Harvest it leaf by leaf instead and it keeps producing until summer heat makes it bolt and turn bitter.
Space and shade for the long game
Leaf lettuce wants 6 inches between plants in rows 12 inches apart, so a dozen plants fit in about 1.5 square feet. It is one of the most space-efficient crops in the garden.
Lettuce also takes partial shade, which is a bonus in summer. A spot with morning sun and afternoon shade slows the bolting that ends the season, so you keep cutting salad weeks longer.
Get your exact number
The planner turns your salad habit into a sowing schedule, not just a count. It works out how many plants to sow and how often to resow, so you get steady lettuce from spring into fall instead of one glut in June.

Questions, answered straight
About 4 to 6 leaf lettuce plants per person in the ground at any time. But the key is to sow a small batch every 2 weeks rather than a whole season's worth at once, so you get steady salad instead of a glut then a gap.
Succession sowing. Plant a small batch, then sow another every 10 to 14 days. Leaf lettuce matures in about 45 days, so staggered sowings give you a continuous supply instead of everything bolting the same week.
Yes, with leaf types. Pick the outer leaves and leave the growing center, and one plant keeps producing for weeks. This cut-and-come-again method stretches a small planting much further than pulling whole heads.
Summer heat makes lettuce bolt, sending up a flower stalk and turning the leaves bitter. Grow it in spring and fall, give it afternoon shade in warm weather, and keep it watered to slow bolting.
