Romaine lettuce is an all-season plant that’s known for its crunchy texture and crisp flavor. With just a little bit of knowledge, you can grow your own greens to enjoy as fresh salads or in recipes such as Caesar salad.

Romaine lettuce is a type of leafy green that is grown for its crisp, slightly bitter leaves. It can be grown from cuttings and can also be bought in the form of seedlings or plants.

Lettuce is the one ingredient missing from my burgers and salads. Lettuce, one of the most adaptable green vegetables, is a staple in many salad dishes and may also be used in soups and wraps.

And why not? It’s high in fiber, iron, folate, and vitamin C, and it’s also low in calories.

So, if you’re a health-conscious individual seeking for something hearty and healthful to cultivate in your backyard garden, Romaine Lettuce is a great choice.

And, to ensure a large output each year, we covered all you need to know about growing and caring for romaine lettuce.

Romaine Lettuce Types

The first and most important thing to select is the kind of romaine lettuce you want to grow, and this guide will assist you in making the best decision possible. Here’s a quick rundown of who they are.

Duo Caesar

Are you worried that all the green color from lettuce will dull your home garden? What if we told you it does not have to be this way? Say hello to Duo Caesar, lettuce made by combining Noga and Cimarron lettuces.

The difference in color is what distinguishes this pair from other lettuces. While Cimarron lettuce has reddish leaves, Noga lettuce has primarily green leaves, which adds interest to the home garden (you don’t always need flowers and foods for that).

Furthermore, they may be picked while they are young, allowing for an early harvest.

Cos. of Parris Island

Parris Island, a barrier island in Beaufort County, South Carolina, is the name of this romaine lettuce variety. The larger leaves (10-12 inches in length) have a crisp, sweet flavor that makes them ideal for lettuce wraps.

It also grows quicker than most other lettuces, so you won’t have to wait as long for your harvest. To top it off, they have a high level of resilience, allowing them to readily avoid issues like tip burn and mosaic virus.

l’Hiver Rouge

l’Hiver Rouge or should I say Red Winter is another lettuce that is sure to make people look twice. The reason being, the attention-grabbing color combination where the leaves are greenish at the bottom and reddish-maroonish at the top.

It also boasts huge 12″ leaves that are resistant to concerns like as tip burn. 

Baby Sweetie

If you have a smaller home garden (or less space) and need more compact lettuce to grow, your search ends at Baby Sweetie. And while the leaves are only about 5-8 inches, their juicy taste makes them great for salads. 

They also have the best durability, meaning that this plant can endure for weeks and can be planted in harsher climates because to its great heat tolerance. Keep in mind, though, that their sluggish development means you’ll have to wait for the harvest.

Heirloom Jericho

Like Baby Sweetie Lettuce mentioned above, this type is also more suited for hotter regions and boasts of excellent resistance that keeps away issues like tip burn and mosaic virus. Plus, unlike other lettuce leaves, this one has heads that don’t go bitter as quickly.

Ruby Gem

This baby lettuce gets its name from its scarlet leaves and is one of the easiest to grow lettuce varieties. It stands around 6-inches tall and has a crisp, juicy flavor that makes it a fantastic salad accent. 

Sun, Water, and Soil Requirements for Growing Romaine Lettuce

First and foremost, you must prepare the soil, as shown below.

Check the pH of the soil. In neutral soil, most green plants, such as spinach and lettuce, thrive. That is, the pH should be in the range of 6.0 to 6.5.

If the soil in your location is sandy or clay-like, don’t worry; a little compost will perform wonders. Just make sure there’s at least 2-3 inches of compost in there and that you work it in approximately 5-6 inches deep.

You don’t want your lettuce to be bitter, do you? Are you looking for a quicker germination time? Fertilization is the solution in either case. Lettuce, like other plants, need fertilization, and we recommend using a fish emulsion fertilizer for this.

Fertilizers rich in nitrogen, phosphate, and potassium are also important for lettuce growth, and a 16-16-8 fertilizer will do the trick. Remember to put it in before you start planting.

If you want to go the additional mile for your lettuce seedlings, fertilize them three to four weeks after planting. You’ll need roughly 14 cups of 21-0-0 nitrogen fertilizer for this.

The one thing you should avoid doing with any lettuce plant in the afternoon is exposing it to the intense, harsh sunshine. Find a location that is shaded in the afternoon but receives enough of sunshine early in the morning for a large yield.

You may also use a floating row cover or plant it among taller plants to give it some much-needed shade. 

This is because lettuce leaves bolt when exposed to direct sunshine, rendering them useless. 

But what if it continues to bolt? Replanting is an excellent option in this instance since the abrupt movement shocks the plant and prevents it from bolting. 

Aside from sunshine, it requires plenty of water, therefore water the plant at least 4-5 times each week to keep the soil wet.

What Is the Best Way to Plant Romaine Lettuce?

Planting lettuce may be done in a variety of ways. A typical home garden is one option. If you don’t have the room, lettuce may also be grown in pots and containers.

Hydroponic soil-free units or a vertical garden are another wonderful choice for producing lettuce (another great solution for people with less space).

We suggest planting lettuce in the spring if you’re wondering when is the ideal time to do it. You may also start it inside and take it outdoors after the summer peak has passed, since this will avoid bolting from sunlight exposure.

The worst season to sow lettuce is in the fall, when the frost will destroy the plant in a couple of days. 

While the lettuce seed is small, the plant expands out quite a bit as it develops, making it even more crucial to space it correctly. A distance of 10-16 inches would be great. 

As a result of the enhanced air circulation, you will have better heads. By removing extra moisture, it also minimizes the risk of sickness.

If you’re using saplings, do it in the evening to avoid the plant being dehydrated from the sudden heat.

Mulching is another thing you’ll want to make sure you’re doing. Mulching keeps moisture and nutrients in the soil while also keeping weeds at bay, so it’s a win-win situation.

How Should You Handle Romaine Lettuce?


After all that work, the last thing you want is for pests and bugs to consume your romaine lettuce, right? Here’s how to look after your romaine lettuce. 

Slugs, bunnies, and a condition known as Shot Hole sickness are all threatening your lettuce leaves. This is a fungus that causes a hole in the leaves that appears like it has been shot. 

Don’t worry, however; safeguarding your lettuce leaves isn’t difficult. Diatomaceous earth is our go-to bug repellant. These boulders may be put near plants to emit an odor that repels them.

You may also use natural methods like as soaps. Another efficient option is companion planting. Garlic, for example, has a strong odor that repels pests.

If rabbits are a concern, use chicken wire or floating row covers, while slug traps may help keep slugs away. 

Also, ensure sure there is no standing water around the plant, since this might cause fungal diseases. Additionally, it attracts aphids. 

Another efficient approach for preventing the illness from spreading to your lettuce leaves is pruning (removing the affected area of the leaf).

What is the best way to harvest Romaine Lettuce?

It’s simple to harvest the lettuce leaves. It may be accomplished in one of two ways:

One, you use your hands to pull the whole plant out. Don’t worry, you won’t need hulk-like hands to accomplish it since the lettuce doesn’t have deep roots.

You may either just remove the leaves or cut it out and leave the head.

However, how will I know when the romaine lettuce plant is ready to be picked?

Romaine lettuce is a fast-growing plant that should be ready to harvest in 55-60 days. Don’t put off harvesting for too long. That’s because the plant’s lush green, luscious leaves will become bitter once it goes to seed. 


If you want to lose weight by eating salads and drinking green juices, lettuce is the plant to have in your backyard garden.
