Lettuce is one of the first things that many gardeners start to grow, and romaine lettuce is a firm favorite. Today, we’ll look at how to harvest Romaine lettuce. We’ll also discuss how to keep it growing! That way, you get ongoing harvests. And oodles of fresh lettuce leaves!
Romaine lettuce is tremendously easy to grow and tastes fantastic picked fresh from the garden, whether as part of a crisp salad or added to sandwiches and wraps.
We want to show the best way to harvest romaine lettuce reliably. And – how is romaine lettuce different from other lettuce crops.
Let’s take a closer look!
What Is Romaine Lettuce?
Romaine is a variety of lettuce that originates from Greece. It is one of the most heat-tolerant lettuce cultivars, making it popular with gardeners in warmer climates. Another name for romaine lettuce is Lactuca sativa – and many Americans refer to romaine lettuce heads as hearts. (Everyone loves a fresh romaine lettuce heart.)
It also has many other nicknames! Cos, butterhead, and leaf lettuce are most common. No matter the name, this tasty lettuce produces tight heads of long, crisp leaves, with a thick center stem on each leaf. The outer leaves can be slightly bitter, while the inner leaves are sweeter and more tender.
How Do You Grow Romaine Lettuce?
If you’re new to growing vegetables and salad, then romaine lettuce should be at the top of your must-buy seed list! Sow the seeds directly in the soil. Or into pots and gro-bags. You can even sow a lettuce crop in your hanging baskets and window boxes!
Lettuce seeds can get started in a seed tray either in the house or in a sunny greenhouse. When your seedlings are around four weeks old, they should be large enough to transplant outside.
You can also sow romaine lettuce seeds directly into the ground. Sow them either outside, in the greenhouse, or under a cloche. Tiny peat pots also work.
Sow the romaine transplants around twelve inches apart. Thin them out as they start to grow larger. Don’t throw away these mini lettuces, as the baby leaves are delicious in a salad!
The best part about romaine lettuce is that it grows (relatively) effortlessly once established. Then all you need to do is keep your lettuces well-watered and watch them grow.

How to Harvest Romaine Lettuce
Romaine lettuce is ready to harvest as soon as the leaves look big enough to toss into a salad – or sandwich! It’s a forgiving plant – and we recommend harvesting before the romaine heads grow too firm.
There are many ways to harvest romaine lettuce, so you can choose a method that works best for you. When pruning and collecting lots of lettuce quickly? Either pull the plant up from the ground or cut it off at the base.
Harvesting whole lettuce with the roots will keep it fresh for longer in the refrigerator, or you can pop it into a shallow jar of water in a cool place. You will need to wash the soil from the lettuce base and the roots. Otherwise, your salad will taste dirty!
(Some homesteaders don’t mind a little dirt in their salad. But – I much prefer a thorough rinse.)
Once harvested – your romaine lettuce lasts for about a week or two in the fridge.
Lettuce harvested in this way will not stay fresh and crisp for quite as long as a plant with the roots still intact. However, there are some excellent advantages to this technique.
Firstly, the lettuce stump will regrow and give you a second lettuce crop! This regrowth may not be as abundant as the first crop, but if you’ve got the space in your garden to leave the stump. Then give it a go. We love a two for the price of one crop round here!
Secondly, leaving the roots in the ground will help to keep your soil healthy. The vegetable roots provide nourishment for your next crop when they rot down, helped along by an abundance of microorganisms.
