Your rating: None Average: 4.1 of 5 (160 votes)

Botanical name: Lactuca sativa

Plant type: Vegetable

USDA Hardiness Zones: 4, 5, 6, 7, 8, 9

Sun exposure: Part Sun

Soil type: Loamy

This is a half-hardy vegetable that you can keep growing all season long by planting one small crop at a time. Days to maturity tend to be short. Garden lettuce is far superior, in both taste and vitamin A content, to supermarket brands.

Planting

  • Lettuce is a cool-season crop that grows well in the spring and fall in most areas. Lettuce seedlings will even tolerate a light frost. Temperatures between 45 F and 65 F are ideal.
  • Loose, fertile, sandy loam soils, well-supplied with organic matter are best. Soil should be well-drained, moist, but not soggy with a slightly acidic pH of 6.0 to 6.5. Since the seed is so small, a well-tilled seedbed is essential. Large clods will reduce germination.
  • Start seeds indoors 4 to 6 weeks before last spring frost date for earliest crop.
  • One week before setting seeds or transplants in the ground, till in compost or organic matter, especially if you have heavy soils.
  • Harden off seedlings for about one week, and transplant outside between 2 weeks before and 2 weeks after last spring frost.
  • Direct sowing is recommended as soon as the ground can be worked. Plant seeds ½ inch deep. Snow won’t hurt them, but a desiccating cold wind will.
  • Seed may be sown in single rows or broadcast for wide row planting. When broadcasting, you'll need to "thin" for the proper spacing.
  • Leaf lettuce: Plant 4 inches apart.
  • Cos and loose-headed types: Plant 8 inches apart.
  • Firm-headed types: Plant 16 inches apart.
  • Your rows of plants should be 12 to 15 inches across.
  • Cover the seeds with 1/4 to 1/2 inch of soil.
  • Water thoroughly at time of transplant.
  • Consider planting rows of chives or garlic between your lettuce to control aphids. They act as "barrier plants" for the lettuce.

Care

  • You should be able to sow additional seeds every two weeks for a continuous harvest throughout the growing season.
  • Fertilize 3 weeks after transplanting. Lettuce prefers soil that is high in humus, with plenty of compost and a steady supply of nitrogen to keep if growing fast. Use organic alfalfa meal or a slow-release fertilizer.
  • To plant a fall crop, create cool soil in August by moistening the ground and covering it with a bale of straw. A week later, the soil under the bale will be about 10 degrees F (6 degrees C) cooler than the rest of the garden. Sow a three foot row of lettuce seeds every couple of weeks—just rotate the straw bale around the garden.
  • Make sure soil remains moist but is well-drained.
  • An organic mulch will help conserve moisture, suppress weeds, and keep soil temperatures cool throughout the warmer months.
  • Lettuce will tell you when it needs water. Just look at it. If the leaves are wilting, sprinkle them anytime—even in the heat of the day—to cool them off and slow down the transpiration rate.
  • Weed by hand if necessary, but be careful of plant roots: They are shallow.
  •  Planning your garden so that lettuce will be in the shade of taller plants, such as tomatoes or sweet corn, in the heat of the summer, may reduce bolting.

Pests

Harvest/Storage

  • Lettuce should be harvested when full size, but just before maturity. You want it young and tender.
  • Before maturity, you can harvest leaf lettuce by simply removing outer leaves so that the center leaves can continue to grow. Butterhead or romaine types can be harvested by removing the outer leaves, digging up the whole plant or cutting the plant about an inch above the soil surface. A second harvest is often possible this way. Crisphead lettuce is picked when the center is firm.
  • Mature lettuce gets bitter and woody and it will go bad quickly, so check your garden everyday.
  • As time passes, you will want to cut the whole plant from the ground.
  • It’s best to harvest in the morning before leaves have been exposed to sun.
  • Keep lettuce in the refrigerator for up to 10 days in a loose plastic bag.

Recommended Varieties

  • Crisphead: 'King Crown', 'Mission'
  • Cos (Romaine): 'Wallop', 'Paris White Cos'
  • Loose Heads: 'Burpee Bibb'
  • Red Leaf: 'Red Sail' (Not recommended for hot weather, their red pigment absorbs more heat.

Hello, i am australian so it is much more warmer here, i am growing iceberg lettuce and the colour is a realy rich dark green, after 4-5 weeks or so, they start to turn a brown colour and start to die, 2 weeks more i have spotted little holes in the leaves, the soil is fine and they get watered around 5 o clock every night. I' ve been trying to grow lettuce for a year now but bugs or animals or something are eating them. Please any suggestions

First year with raised garden

By Rjgator

First year with raised garden bed. Have no idea of what things should look like but my plants are doing well. Have lettuce. It isn't growing in a bunch per see more of leaf here and there. Was I supposed to cut these first leaves off so the plant forms a head or what? Or, do I just pick the leaves and eat them as is? Thanks!

Most of your

By Almanac Staff

Most of your questions/curiosity can be resolved above. Did you start with seeds? Perhaps you should have started these indoors... If you started with seeds outdoors, a number of things could have happened: birds ate them; the seeds were not consistently wet and/or warm enough; or they were too wet; or the soild was too heavy. The resulting crop should resemble the image on the seed packet, if you used seeds, or on the plant stick, if you bought seedlings. You can also do an internet search to find an image. When you pick the leaves, you should probably wash/rinse them to eliminate any soil bits. (Do not use soap. Water alone is adequate.) Then you eat them, yes. There is still a lot of summer left. Review the advice above, too, and consider trying lettuce again...

I've regrown some romaine

By Allie Kratz

I've regrown some romaine lettuce from the base, and it was flourishing in the water I kept it in. The leaves began growing back and it has been sprouting up at a decent rate. I've recently transferred it to some soil in a jar by one of our kitchen windows and it is doing quite well.

This is the first time I am growing lettuce on my own. When would you recommend I pinch the top leaves off in order to encourage thicker growth at the base?

In addition to the above, what would you recommend for a small condo-esque garden?

Lettuce would prefer 5 to 6 hours of sun but not a lot of heat so it's a cool season crop (temperatures below 85 degrees F). However, you can get by with partial partial sunlight or shade. Plant a few seeds; they grow in a few weeks and see how it goes.

It will depend on the exact weed killer used as to how long you need to wait. Some are designated "safe" for vegetable gardens, or for certain vegetables, while others are not. If you can, ask your neighbor what s/he used and then call the manufacturer for best advice.

Hello. This is my first

By Heather E Ryan

Hello. This is my first season of gardening, so I don't know much. I planted lettuce directly into raised bed. After 1 day of sprouting, an entire row disappeared. I can still see the roots going into soil, like something ate all the tops off. What pest do you think is the likely culprit, and how do I stop this from happening again. I'm in climate zone 9. Thank you for any help!

Hi, Heather: Thanks for your

By Almanac Staff

Hi, Heather: Thanks for your question, and special thanks to Sara J for jumping in here, too! This could be any number of things, including caterpillars, 4-legged critters, or even birds, but slugs are likely suspects, as Sara says. The first thing to to do is set your alarm and go out a couple times at night to see what you can see. Try putting some temporary screening over them to eliminate the possibility of munching from the outside. Then, if necessary, to go after slugs you can try a variety of soil sprinklings, including diatomaceous earth, garlic, salt, hot pepper flakes, or coffee grounds (but not too much). We use beer for slugs. Set a jar lid in the soil such that its top is at soil level. Slugs will fall in and drown. Remember to refill after rain (or craft a little mini umbrella). Screening is best for this, too, because humans and slugs aren't the only lovers of beer. Thanks again!

Did you notice the damage in

By Sara_J18

Did you notice the damage in the morning (i.e. It was fine the night before)? In that case, it sounds like you could have a snail problem; they come out/feed at night and can decimate a garden. Get a snail killer or for a more natural method in a raised bed you could consider smearing magnesium, I think it is, around the exterior of the container? I believe it burns snails.

By Heather E Ryan

I believe it happened overnight. I saw the sprouts yesterday around noon, then today by 10-11ish I noticed they were gone. Thank you for the info. I'm going to check tonight to see what I can find, and I'll look into the magnesium. Thanks again!

By Heather E Ryan

Thank you! It turned out to be slugs and snails. I set beer traps but mostly I go hunting at night. That seemed to do the trick for about a week now, but then today a row of lettuce sprouts disappeared, but during the day. I did not see any slime trails. Any ideas on what could have happened? How do you use wire to protect them?

Thanks for the help!

We have ice berg lettuce in

By Sandymascarenhas

We have ice berg lettuce in our garden and it is meant to form a head and because we have it out in the sun we are worried that the plants have just stopped growing..We have used coffee grinds and natural compost such as chopped banana peels and have also enriched the soil with organic compost soil. What could be the problem?

Heading-type lettuce will not

By Almanac Staff

Heading-type lettuce will not form a head if it gets too hot, over 70 or 75 degrees Fahrenheit during the day, and warm nights. They like cool weather--around 45 to 65 degrees F. In heat, the plants will likely bolt (go to seed); it could be that the plants have stopped growing because they are preparing to bolt. To delay bolting, if your area has been experiencing warm temperatures, you might try putting shade cloth over the plants so that they get filtered light. Try to keep them out of the heat of the sun. Be sure to keep up with the watering (but don't overwater). Next year, (if you haven't this year) you might try starting the plants early indoors, so that they can finish maturing outside before hot weather sets in. Look for heat-resistant varieties. Plant in areas that get afternoon shade, or consider planting in late summer/early fall (when temperatures cool) for a fall harvest.
 
Heading lettuce also might not form a head if the plants are too crowded. Iceberg should be about 16 inches apart.

Let it Bolt for the Bees

By Anita Eccles

Let it Bolt for the Bees

The Xerces Society suggests we let our lettuce go to flower. If possible, allow leafy crops, like lettuce, to flower if they don’t need to be tilled right away. This gives bees additional food sources. Being a lazy gardener, I learned this by accident watching how happy our honeybees are visiting our lettuce and radish flowers.

Hello, We have done our

By Michele adlon

Hello,
We have done our first raised beds with organic soil and then beautiful, broken down mulch and love them. Have two problems…our tomatoes are splitting even the smaller ones and my lettuce was doing great, a leaf blend, but then overnight had holes in every leaf. Help!

Although splitting tomatoes

By Almanac Staff

Although splitting tomatoes can sometimes be caused by fluctuating temperatures, they are more often caused by uneven watering (including drought/heavy rain), especially during the late stages of ripening. Some varieties are more susceptible than others. Try to be consistent in your watering and water deeply; adjust during dry periods and with heavy rain. Provide mulch to conserve moisture. If you had a dry spell and heavy rain is predicted, you might harvest your almost-mature tomatoes to catch them before they split; they'll complete their ripening on a windowsill. Harvest split tomatoes as soon as possible; those left on the vine may be subject to insects and diseases.
 
As for the lettuce, it sounds like they might have been attacked by slugs or snails. These pests come out at night to chew vegetation, leaving slime trails and large ragged holes in leaves. Remove any mulch around your plants where these pests like to hide. Pour beer in a small plastic container and sink it in the soil near your plants so that about 1/4 inch of the rim is above the soil. The slugs/snails will drown in the beer. You can also place boards around, where the pests will congregate, and you can then dispose of the pests the next day. For more information, see:

I planted a garden for our

By Jenna Garner

I planted a garden for our local food pantry. Looking good and I planted lots of leaf lettuce in early spring. I already harvested a lot of outer leaves that were big, but it is starting to get really warm during the day. How do you know when the lettuce is bolting? Should I wait and plant the remainder in the fall when it cools? I was originally going to plant every 2 weeks all summer long. I live in southern IL. Love this site!! Thanks!!

Lettuce is bolting when it

By Almanac Staff

Lettuce is bolting when it starts to form a long flower stalk, usually in the center of the plant. The leaves on the stalk will be smaller and more elongated, and eventually, the stalk will form a flower spike. Leaf flavor becomes bitter. Bolting is caused by increasing day length as well as increasing temperatures.
 
For Illinois, you might want to stop the succession planting until late summer (about mid August or so), when you can sow for fall crops. If you do want to give summer growing a try, provide filtered shade all day for your plants, or complete shade in the mid afternoon onward, to protect them from the heat. Be diligent about watering.

Sometimes leggy seedlings are

By Almanac Staff

Sometimes leggy seedlings are caused by too rich a soil (too much nitrogen), or too warm a soil (seedlings like it cooler than seeds). But more often, it is not enough light. If you are using sunlight, choose a south-facing window, and rotate the seedlings every so often so that they do not grow toward the window but keep upright; if the light is still not enough, supplement it with artificial light (fluorescent bulbs or grow-lights). If you are using artificial light, adjust the height of the bulbs so that they are a bit closer to your seedings (the distance will depend on the bulbs you use, but usually they are positioned about 2 to 6 inches above the plants). In general, try to provide about 12 to 16 hours of artificial light.
 
In addition, you can have an oscillating table fan on the gentlest setting blow air on the seedlings for a few hours each day, which will help them to grow sturdy stems (make sure the air is not too strong for them).

What is good to plant with

By New2gardening

What is good to plant with lettuce to keep the bugs off?

Hi, New2! Official companion

By Almanac Staff

Hi, New2! Official companion plants for lettuce are asparagus, beets, brussels sprouts, cabbage, carrots, corn, cucumbers, eggplant, onions, peas, potatoes, radishes, spinach, strawberries, sunflowers, and tomatoes. Broccoli is a no-no. The trick to keeping bugs off lettuce is to plant something nearby that will attract insect predators, such as ladybugs and parasitic wasps, that will eat bugs such as aphids. Toward that end, think about dill, parsley, marigolds, nasturtiums, and cosmos. You're in your salad days of gardening ... good for you!
 

Hello I have a question

Question Folks have small

By Lee Walden

Question Folks have small Varity of lettuce doing well do I crop off flowers at top of plant Thanks

Yes, cut off those flowering

By Almanac Staff

Yes, cut off those flowering stalks. When lettuce forms a flowering stalk and blooms, it is called bolting. This will make the lettuce more bitter, but you can try to slow it by cutting off the stalks as soon as you see them develop. You might also be able to slow or discourage bolting by partially shading the lettuce from the heat, keeping the soil evenly moist (but not soggy), and harvesting the outer leaves at regular intervals. Bolting happens when the temperatures become warmer and daylight lengthens. As an alternative, when you see signs of bolting, harvest the entire plant before the leaves become bitter.

I usually have good luck growing lettuce in raised beds and over wintering under plastic. THis year the lettuce is very dry and stringy, wilting on picking, and not growing very fast. The only thing I did differently is to add some gypsum (mixture of CaSo4 and MgSo4--"Soil Doctor") last fall because we have a heavy clay soil. Is gypsum harmful to lettuce?

First, make sure that you

By Almanac Staff

First, make sure that you have a "heading" variety such as Iceberg or Romaine if you want a head to form.
Some types, such as Bibb lettuce, form a loose head. Iceberg won't head tightly in warmer climates and you should treat it as a leaf lettuce and harvest the leaves as they get large enough to eat. 
Lettuce will head better if it stays cool. In warmer climates, it can be better to grow lettuce in the fall.

By lynordb

Is it best to sow or plant rows of my Romaine Parris Island Cos, if I want to have some all year long, and want to save my seed? And when do I try to make it seed, at the very end of the year, or at the end of each planting?

it's best to direct sow

By Almanac Staff

it's best to direct sow lettuce seeds in single rows or broadcast for wide row planting. If you broadcast (as the seeds are so tiny), you'll just thin to the right spacing. We like to take a row and just plant a square every 2 or 3 weeks so that we have a continual harvest
Lettuce seeds are so tiny and hard to collect, so we don't usually save this crop. If you wish to try, go for it!
1. Leave a plant or two to produce a
seed stalk.
2. After the plant blooms and the flower
forms a miniature “dandelion head,”
gather the seeds.
3. Separate the seeds from the chaff by
rubbing them with your fingers

By Almanac Staff

Lettuce can take a light frost though no more. Cover growing beds with row covers or blankets or throw-cloths supported by stakes or wires. Milk jugs can cover individual plants. Mulching is a good way to protect very small gardens. Use several layers of newspaper, straw or chopped cornstalks.

Is it possible to grow lettuce year round inside, as long as it is exposed to sunlight?

Yes, you can grow lettuce

By Almanac Staff

Yes, you can grow lettuce inside year-round, though we'd grow outside when you can. The main requirement is sunlight. Place pots in a bright, sunny south-facing window. In many regions without strong winter sunlight, you'll need to supplement with a combination warm-white/cool-white fluorescent fixture. You'll know if the light is insufficient light because the plants will get leggy and tall.

There are many varieties of lettuce that do not grow into a head. Leaf lettuce is probably the most popular and  you will see individual leaves loosely arranged on the stalk. Stem lettuce would be unusual; it forms an enlarged seedstalk and you might see it in Chinese dishes.

My lettuce and brocoli

By Deborah Trujillo

My lettuce and brocoli produce plenty of flowers but not seed. My garden is at 3400 meters with cold nights and warm to hot days. What is going wrong?

All these veggies will go to

By Almanac Staff

All these veggies will go to seed eventually. Lettuce can need some help for the flowering stalk to emerge. Try using a knife to slit the heads partially open. The seeds will start to ripen though it may take 2 weeks. Your broccoli should throw up a tall flower stalk covered in lots of small yellow flowers. The flowers should form slender seed pods. Once they begin to look dry, cut the plant and remove the seeds from the pods.

When harvesting individual lettuce leaves, where on the plant do you cut if you want them to regrow? Should you leave a little of the leaf (where it connects to the stem) or is a clean cut better?

Harvest leaves starting at

Harvest leaves starting at the outside of the plant, leaving the central bud to grow more leaves. Or, if the lettuce is closing to going to seed, just cut the entire plant at the soil line.

By Jon Naranjo

How do you know exactly when lettuce is mature? First timer with lettuce but we are kind of using the store size as scale? one can pull off leaves as its growing for salads or sandwiches? what if your leaves taste kind of bitter?

Really, you can harvest

By Almanac Staff

Really, you can harvest lettuce any time after true leaves form. It's better to pick lettuce earlier vs. later; it gets that bitter taste if you leave it too long. Grocery store leaves are much bigger. If you harvest the outer leaves first, it lasts longer. Harvest in the morning when leaves are full of moisture.

How do I produce my own

By MissB

How do I produce my own lettuce seeds without buying them at the store?

You can "save" and "exchange"

By Almanac Staff

You can "save" and "exchange" seeds with other gardeners. After the weather gets too warm for lettuce, it will "bolt" and grow a flower on a long stem. The flower will produce seeds which will start to dry up as the lettuce dies. Before they are completely dry, shake them off the stalk onto a piece of paper and let them dry. Lettuce seeds are very small and black. Store in a cool dry environment, in an envelope, or in a small glass jar until next planting season.
