It might seem like there's not much to do in the garden at this time of year, but learning how to grow winter salad should be at the top of your list – especially if you have a small vegetable garden.
Now, leafy greens are the perfect superfood. They're tasty, nutrient-dense, and counted among the easiest vegetables to grow. They also look quite pretty, making them incongruous in a garden border as they are in a designated vegetable bed.
'Learning how to grow winter salad is great fun and an easy way to harvest some fresh food from the garden, even during the colder months of the year,' promises Morris Hankinson, director of Hopes Grove Nurseries.
He adds that winter salads don't need a lot of outdoor space; they can also be grown in containers, hanging baskets, and inside a greenhouse.
'Why not experiment on a warm windowsill and see if you can grow any lettuce leaves? It’s all good fun!'
What you will need
If you're planning on growing your own winter salad, you'll be pleased to know it's one of the more inexpensive GYO options. All you really need is...
- A selection of cloches and horticultural fleeces (we rate this stylish lantern cloche with lid from Crocus, but any plastic cloche or bog standard fleece will do)
- A good peat-free compost, such as Levington PEAT FREE Seed Compost (with added John Innes) from Amazon
- A variety of winter salad seeds (plenty to choose from at Thompson & Morgan)
REMEMBER: Not all summer lettuce will grow over the winter, so look out for the right varieties.
If you need help with this, Morris suggests picking up a few seed packets of the following...
- Mizuna is a delicious, crisp and mild Japanese green which grows well in the winter months.
- Lettuce ‘Winter Density’ grows well throughout winter and is a tasty salad leaf.
- Kale ‘Winterbor’ can be used in salads and is full of nutrition, growing all winter.
- Mustard Greens grow well in winter, adding a spicy touch to salads through the colder month.
- Spinach ‘Winter Giant’ is large leafed with dark green leaves and packs a punch of nutrition in a winter salad.
Step-by-step guide
Once you have all the equipment you need to grow winter salad, it's time to set to work. And, thankfully, it's all incredibly straightforward (so long as you've learned how to sow seeds successfully, of course).
1. Choose the right moment
Just as important as learning how to grow winter salad is, of course, learning when to grow winter salad.
'Ideally you’ll need to start sowing winter salads in late summer or early autumn, but why not give it a try even later on?' says Morris.
'They do need time to establish before it gets cold, so if it’s a warm autumn there’s still time. Make sure the soil is well prepared with some well rotted organic matter and good drainage.'
2. Find them a sheltered spot
As is so often the case when learning how to grow your own vegetables, fruit, herbs and more, you will need to think carefully about where you're planting your winter salad seeds.
'Winter salads grow throughout the colder months but they still need protection so if you can sow them in a sheltered spot this will be helpful, especially if you can place them by a south-facing wall where they will get as much sunlight as possible,' says Morris.
'Use cloches, fleeces and cold frames which will give more protection and extend the growing season.'
3. Plant your seeds
When it comes to planting your winter salad seeds, a good rule of thumb is to treat them like any other lettuce seeds and sow them 1cm deep in rows, 30cm apart from each other.
'Water only when needed, ensuring the soil doesn’t dry out completely but is also not too wet, because winter lettuce doesn’t need as much water as other times of the year,' says Morris.
Don't forget to protect them from slugs, snails and some hungry birds by using either chicken wire or fleece – and be sure to sow successionally. 'Basically, this looks like sowing a batch of seeds every few weeks to ensure you have plenty of fresh leaves to harvest regularly for as long as possible,' advises Morris.
