Four Super-Hardy Salad Greens to Grow in Winter

How to grow winter salad leaves

Salads may be the epitome of sunny summer days, but there are also super-hardy salad greens that will grow in winter and cold weather. What a treat! Here are four of our favorites.

Hardy salad greens can be grown outside in milder climates, or with a little protection in colder ones. As the weather warms up in spring, the harvests come thick and fast, at a time when there鈥檚 very little else to pick.

Sow winter salad leaves in late summer or early autumn so they go into winter at just the right size: big enough to survive the chill but not so big that lush growth is clobbered by hard frosts.

Most winter salad leaves can grow outside in mild or temperate climates, but you鈥檒l get more leaves if you can offer some protection from the weather, for example by growing salad leaves in a glass or plastic greenhouse, or under row covers.

So here鈥檚 our pick of the hardiest and most reliable winter salad leaves.

1. Mache, aka Lamb鈥檚 Lettuce or Corn Salad
Mache, which also goes by the names lamb鈥檚 lettuce or corn salad, produces tender leaves with a smooth texture. This is the hardiest salad leaf of our quartet and grows very well outdoors.

2. Land Cress
Land cress, sometimes known as American cress, has rich, dark leaves that taste similar to watercress. It鈥檚 one of the quickest winter salad crops, giving leaves to pick as soon as eight weeks from sowing.

3. Claytonia, aka Miner鈥檚 Lettuce or Winter Purslane
Claytonia, also called miner鈥檚 lettuce or winter purslane, grows soft, succulent leaves and, come spring, tiny white flowers that also make for good eating. Use it in salads or cook it as an alternative to spinach.

4. Watercress
You don鈥檛 need running water to grow watercress, so long as you can ensure the soil it鈥檚 growing in is consistently damp, which shouldn鈥檛 be too difficult in winter. Watercress鈥 mildly peppery leaves make it salad royalty!

Direct Sowing Winter Salad Crops

Winter salad leaves are well suited to sowing direct into ground recently vacated by summer crops. Remove any weeds first, as they might smother your plants, then rake the soil to a fine tilth.

Mark out drills according to the instructions on the seed packet. Depending on what you鈥檙e sowing, rows will be spaced between 9-12 inches (22-30cm) apart. Sow the seeds very thinly then water them. Once they鈥檙e up, thin the seedlings in stages until plants are about 6-8 inches (15-20cm) apart within the row.

Sowing Winter Salad Leaves into Plug Trays

Winter salad leaves are also prime candidates for starting off in plug trays. At sowing time ground is often still occupied by summer crops. But sow into plug trays and your salad leaves may be started off away from the vegetable garden, giving earlier crops a chance to finish. Plug trays also reduce the risk of slug damage at the vulnerable seedling stage and produce sturdy young plants able to outcompete weeds.

Fill trays with general-purpose potting soil then firm it in, adding a little more if needed. Firming in the potting soil creates small depressions in each of the plugs, which are ideal for sowing into. Drop about two seeds into each plug. Some seeds like claytonia are tiny, so don鈥檛 worry if you end up with more鈥攜ou can always thin out the seedlings after they鈥檝e germinated to leave just the strongest in each plug.

Once you鈥檙e done sowing, cover the seeds with a very thin layer of more potting soil, then label your tray so you don鈥檛 forget what you鈥檝e sown鈥攅ssential if you鈥檙e sowing more than one type of plant in a tray! Water the tray with a gentle spray, or place plugs into trays of water to soak it up from below. Remove trays from the water once they鈥檙e ready.

Grow the seedlings on until the roots have filled their plugs, when it鈥檚 time to plant them. If the ground is still occupied by other crops, you can re-pot into bigger pots or plug trays, buying you another week or two before planting outside.

Planting Winter Salad Leaves

Set your winter salad leaves out at the recommended spacing. Planting in a block, so plants are the same distance apart in both directions, is perhaps easiest. Allow 7 inches (17cm) both ways for mache, 8 inches (20cm) for claytonia, and 9 inches (22cm) for land cress and watercress. Dig holes into prepared soil, enriched with organic matter such as compost if it鈥檚 likely to have needed a boost after summer, then pop the young plants in. Fill the soil back around them, firm in and water.

Caring for Winter Salad Leaves

Weeds and slugs are the enemies of winter salad leaves. Keep on top of both. Slug traps, filled with beer to attract them, work to a point, but keeping growing areas clear of weeds and debris, while planting at the correct spacing should do a lot to deter slugs.

How to Harvest Winter Salad Leaves

Harvest leaves once plants have formed mounded clumps. Cut stems with a sharp knife, taking care to leave the lowest leaves and those towards the center untouched so they can continue to grow. As growth picks up in spring, so do the harvests and how much you can remove from plants on each occasion.

By mid spring plants will be flowering. Young flower stalks may be eaten but in time they will become tough. At this point it鈥檚 time to dig up and remove winter salad crops to make way for your summer staples.

If you thought winter meant time to retire the vegetable garden till spring, think again. Winter salad leaves will keep the fresh pickings coming. Tell us down below if you鈥檙e growing some of these sensational salad crops this winter. What are you growing and how?

Am growing a variety of veggies in our greenhouse. This was a one car garage that we converted into a greenhouse! Right now am growing radish, peas, green onions, Tom Thumb lettuce, romain lettuce, spinach, carrots, celery, broccoli and green beans. I had a mini greenhouse full of Ozark Beauty strawberry plants but just transplanted them into the big greenhouse...they are still producing albeit slowed down due to season. Also have a dwarf Meyer lemon tree and Clementine Mandarin tree, small pine tree, herbs and 2 blueberry bushes. We are in Zone 7B so we get cold and some snow...this morning was 22* outside but with small heater greenhouse was 37*...which these plants seem to love! YES! GROW IN WINTER!
