DIY Lettuce Planter: Lettuce in a Wine Barrel

Here is a really quick way to get a lot of lettuce in a short period of time while protecting it from those pesky slugs and snails! Growing lettuce in a lettuce planter keeps it elevated so that pests can’t reach it, plus its shallow root system means it thrives in a container environment, so you will have a huge harvest of lettuce without needing a lot of space.

I decided that one season of slugs eating my lettuce was enough. While I’m inclined to share my garden with the local wildlife, there are a few things I like to keep to myself. That includes my vegetables!

While there are plenty of ways to keep slugs at bay, elevating my lettuce was by far the easiest and most friendly way to keep the slugs away from my stash. Ever year now, I grow plenty of lettuce. It just grows so fast and I gobble it up like there’s no tomorrow.

If you’re looking to make your own lettuce planter, here is exactly how I built my own wine barrel planter and all the best tips for growing lettuce.

Why Should You Plant Lettuce in a Container?

Of course, you can grow your lettuce in a garden bed or in any container you like, but I plant my lettuce in a wine barrel planter for a number of reasons:

• It looks decorative in the garden.
• It grows very quickly.
• It is easy to harvest the lettuce at a raised height.
• It greatly reduces the number of slugs and snails that devour the tender seedlings and the leafy greens.
• You can place it in a partially shady location, like under a tree that will prevent the lettuce from overheating and bolting.

Preparing Your Lettuce Planter

You don’t actually need such a deep planter since lettuce has fairly shallow roots. I like the look of the wine barrel planter, and I enjoy having the lettuce elevated this high for easier harvesting.

You can save soil costs by filling the bottom of the barrel with a large upside-down plastic pot, then top the rest of the planter with a good quality soil mix for containers. I almost always make my own potting mix using one of these recipes.

Alternatively, you can buy a container gardening soil mix of your preference or make your own by adding 2 parts peat moss and 1 part pearlite to 4 parts well composed soil. Mix thoroughly in a wheelbarrow, then fill up the planter.

Types of Lettuce to Grow

Lettuce seeds are really easy to sow either directly or by starting them indoors first. Learn all about seed starting here and for more detailed instructions plus lots of DIYs and tips, see my book on seed starting here.

Nursery lettuce plants are also an option, and are really inexpensive. You can often get six or more for just a few dollars. I think I spent $5 on a mix of seedlings that I planted in this barrel.

When selecting your lettuce, choose some leaf salad greens and not just head lettuce. I love salad greens because I can harvest them as I go and leave behind seeds to quickly replace what I have taken.

Look for salad greens with a mixture of flavor and colour. This will give you the tastiest summer salads. Here are some of my go-tos:

• Red lettuce
• Oakleaf lettuce
• Arugula
• Asian greens
• Mustards
• Kale

Tips for Growing Lettuce

Lettuce grows best in full sun though it does tolerate partial shade (you can easily move it if it gets too hot when it’s in a lettuce planter). When the lettuce is growing, you’ll want to thin seedlings to help the plants grow better. Luckily, you can eat all of these lettuce seedlings!

Since lettuce has shallow roots, this does mean that you’ll have to water regularly. Check the soil at least twice a week and water whenever it’s dry. When it’s hot, check on your lettuce every day.

At the beginning and end of the season, I like to use little umbrella greenhouses to extend my season. They work well when you’re first starting seeds as well as in the fall to keep things warmer for longer for your lettuce.

Of course, my most helpful tip is my wine barrel planter! Elevating the lettuce is the best way to prevent slugs, snails, and other pests from eating up all your lettuce.

Harvesting From Your Lettuce Planter

After just three weeks, this is what the lettuce barrel looks like. Now we are harvesting lettuce every day for our salads, sandwiches, and snacks.

To harvest, you can either cut the outer leaves of the plants or harvest a whole head. If you cut the leaves, the rosette in the center will keep growing, but make sure you harvest it all before it starts to flower (this is called “bolting”), or the leaves will become bitter.

If you harvest a whole head, buy a few more seedlings and replace them as you cut. This way, you will have a constant supply of lettuce throughout the season!
