Lettuces are a cooler-season crop that can be harvested at different times, depending on the variety. In this article post, we will discuss how to harvest lettuce, including tips for baby lettuce and harvesting from your garden. We will also provide information about growing lettuce in containers and hydroponically. Let's get started!


The first thing to know about harvesting lettuce is that not all types of lettuce are the same. There are multiple varieties, which we will go through later in this post, but for now let’s focus on the two most common: head or bunching lettuces vs leaf lettuces.


What are the Different Types of Lettuces?

There are many different kinds of lettuce, but the most common are iceberg, romaine, and butterhead. Iceberg is a crisp, light green head that is perfect for salads. Romaine is also a light green color, but it has a more robust flavor than iceberg. Butterhead has soft leaves and a delicate flavor. There are also many different kinds of baby lettuce, which are perfect for salads or as an addition to other dishes.


Can You Grow Lettuce Indoor?

You can grow lettuce indoors, but you'll need to make sure you have plenty of light. Lettuce prefers full sun, so if you're growing it in a container, place it in a sunny spot. If you don't have enough natural light, consider using artificial lighting.


Lettuce is easy to grow and doesn't require a lot of care, making it a great choice for beginning gardeners.

In addition, to be grown easily, lettuce is also very versatile. You can eat it raw and cooked, and there are many different types of lettuce to choose from, including iceberg lettuce, romaine lettuce, and butter lettuce.


Lettuce is also a great vegetable to grow in containers because it takes up very little space, making it perfect for small yards or patios.


You can easily grow lettuce from seed indoors, but if you want to start growing sooner rather than later, try buying transplants at your local nursery or garden center instead of starting seeds yourself at home.

How to Grow Lettuce - Start an Indoor Lettuce Garden

First, you have to know how to grow lettuce. The instructions for growing and harvesting lettuce are different, so we will go over that first(growing-lettuce). Then we’ll focus on how to harvest your lettuces when they are ready.


There are three ways to grow lettuce- in the ground, in containers, and hydroponically. The easiest way to grow lettuce is in the ground. You can either direct sow or transplant seedlings into your garden. Make sure to plant them in a sunny spot with well-drained soil. If you live in an area with hot summers, make sure to give your lettuce some shade in the afternoon during the hotter parts of the day.


When to transplant lettuce seedlings? It takes about three weeks for baby lettuce to grow from seedlings. You can transplant them when they are two inches tall and have their first set of true leaves. When your soil has warmed up adequately, you can sow the seeds directly into the ground.


Lettuce Containers: Lettuce in Pots

Lettuce can also be grown in containers. You can either use a pot or container that is at least six inches deep, or you can grow them in a barrel or window box. Containers are great for small gardens and if you want to have control over the soil quality. However, they may need to be watered more often than lettuce planted in the ground.

Hydroponic lettuce is a great option for those who don’t have access to good soil or if you live in a place with a short growing season. Lettuce can be grown hydroponically indoors or outdoors. Hydroponic lettuce is grown without soil and requires a nutrient solution to grow. The plants roots are suspended in the nutrient solution, which provides all the nutrients they need. While hydroponics can be a great option for growing lettuces, it does require more maintenance than growing them in containers or in-ground.


The best time to plant your lettuce will depend on where you live and how you want to harvest it. If you’re planning on harvesting baby greens then start sowing seeds directly into your garden bed every couple weeks from early in the spring until mid-summer (April through July).


If you don’t have room in your garden to plant lettuce, you can grow it in containers on your porch or patio. Choose a container that is the very least six inches deep and has drainage holes. Fill it with potting mix and add a handful of organic matter like compost or manure to help improve the soil. Start by directly sowing seeds into your container every two weeks from April through July for baby greens. You can also start seedlings indoors in February if you want to get a head start on growing lettuces before spring arrives!


If you live in a place with short growing seasons, hydroponics might be an option worth considering. It allows you to grow plants year-round without relying on good weather conditions outside – which makes it perfect for those who don’t have access to land or live in climates where winters are too cold/snowy/wet etc… Hydroponics systems vary greatly when it comes down to how they run (ie: some have pumps while others are gravity-fed).


This is also great for those who don’t want any maintenance during their harvests! You can find hydroponic systems online or at your local garden center. Once you set up this system, just add seeds into the growing medium and let them do their thing – don’t forget about them though!


The best part about growing lettuce in hydroponic systems is that it’s easy to harvest them as baby greens, mature heads, or whole plants. All you need are scissors and a bucket for water (or just hold them under running water). The main downside? You can’t grow root crops like carrots so don’t expect any French fries from this setup…


Planting Lettuce Seeds

How far apart to plant lettuce?

Lettuce seeds are tiny, so you can sow them quite close together. I usually plant them about ½ inch (13 mm) apart and then thin out the weaker plants when they’re a couple of inches (about 50 mm) high. You could also broadcast the seeds thinly over the surface of the soil and then rake them in gently.



When to plant lettuce?

In most parts of North America, you can plant lettuce outdoors from early spring until late summer. The best planting time depends on the type of lettuce you are growing. For example, some types of ‘leaf’ lettuces can be planted as late as mid-summer, while other types, such as romaine or iceberg, should be planted in early spring.


Lettuce is a cool-weather crop and does best when soil temperatures are between 60-70°F (16-21°C). You can plant lettuce either as direct seeding into the ground or you can start them indoors a few weeks before transplanting. If you have hot summers, I suggest planting your lettuce in containers or using hydroponics instead of growing it in the ground.


How Much Sun Does Lettuce need?

Lettuce needs at the very least six hours of sunlight per day to grow well. If you're growing lettuce in containers, move them around throughout the day so that they get enough sun.


If your lettuce gets less than six hours of sunlight, consider growing leaf lettuce instead. Leaf lettuce can tolerate a little bit of shade and still produce good yields.


You can also grow lettuce hydroponically indoors under LED lights if you want to have a consistent supply of fresh lettuce all year long. I have 12 hours of light on and off.

Another option is container gardening if space isn't available outside. Lettuce will grow well when planted in containers that are around six inches deep with drainage holes.

Now let's talk about how to harvest your lettuce bounty!

Now that we’ve gone over generally how to grow lettuce, let’s focus on how to harvest lettuce so it keeps growing!


How to Harvest Lettuce Without Killing The Plant

Lettuce is a quick-growing plant and the leaves are ready to harvest just weeks after they sprout. But how do you harvest lettuce so it keeps growing? And when is the best time to cut your lettuce? Cutting lettuce at the right time is important. It ensures you have a steady supply of lettuce from one harvest to the next. One way to harvest lettuce is to pick the leaves as needed. This is called cutting lettuce. Another way to harvest lettuce is by pulling the entire plant as it grows and planting another in its place so you have a continuous supply of lettuce year-round.


Another method of how to harvest lettuce is by cutting the top off and leaving about 2 inches in the ground so that it will regrow quickly and you'll have another harvest in no time!

Lettuce is a cool-weather plant. Lettuce grows well in spring and fall when temperatures are less than 80 degrees Fahrenheit. It can also grow in early summer, but it needs to be planted in partial shade.


When growing lettuce, you should know how long each type of lettuce takes to mature. Some varieties take longer than others to reach maturity (60 days or more). The time needed for your lettuce plants depends on the variety you are growing:


Butterhead lettuces (Bibb) - 50-70 days from seedling or 32-45 from transplants


Crisphead lettuces (Iceberg) - 75-80 days from seedlings or 60+ from


It can be difficult to grow lettuce during the summer months because it prefers cooler temperatures and doesn't tolerate heat very well. The only way to grow good-tasting heads of leafy green lettuces like butterhead (Boston Bibb) or romaine (cos) during summer is with partial shade from other plants that provide some protection from direct sun during the hot parts of the day.


How to Harvest Romaine Lettuce?

The best time to harvest romaine lettuce is when the leaves are about 12-14 inches long. To harvest, cut the head of lettuce off at the base just above the root. If you plan on harvesting more than one head of romaine, leave a few inches of stem attached so it will regrow.


How to Harvest Iceberg Lettuce?

Iceberg lettuce is ready for harvest when the heads are firm and have a crispy texture. The recommended size for harvesting iceberg lettuce is between six and eight inches in diameter. To harvest, cut the head of lettuce off at the base just above the root.


How to harvest salad greens?

The best time to harvest salad greens is when the leaves are about four inches long. To harvest, cut the leaf off at the base just above the root. If you plan on harvesting more than once, leave a few inches of stem attached so it will regrow.
