Bagged salads are (weight for weight) one of the most expensive items on the supermarket shelves and they rise even higher in winter. Growing your own is easy to do, because winter salads tend to feature oriental salad mixtures and these thrive in cooler temperatures.
If you sow seeds in September (or in greenhouses in October), you should be able to pick two or three times a week from mid-October right through until March because winter salads grow slowly due to cooler weather and lower light levels. You’ll be eating really fresh leaves, full of vitamins for virtually nothing.
If you want to keep a crop going through the coldest weather, you will need some winter protection in the shape of a cold frame, or unheated greenhouse.
If you don’t have either, make a small raised bed in a sheltered part of the garden and cover it with thick horticultural fleece on cold nights. Harrod Horticultural sell a good one.
Sow winter salad seeds in September.
You could buy separate packets of seeds, or invest in winter salad mixes. There are spicy oriental ones containing different mustards and milder Mediterranean ones on offer.
Always grow some rocket, it’s a particularly useful crop in winter because it doesn’t suffer from flea beetle.
You can use ready grown plugs from seed companies online.
If you’re growing tomatoes in an unheated greenhouse, you will be able to use the same space for salad crops.
Remove your tomatoes by mid-October and tidy up the bed and then pop your winter salads in. A frost-breaking heater will keep your plants frost-free in very cold weather.
The Italians grow winter salads and their seeds are tested in the Alps. They offer good value and Italian winter salads have a much milder flavour than the spicy oriental ones.
Most winter lettuces form heads: they curl their leaves to keep out the cold, so allow them to heart up before harvesting.
This will also provide shelter and drainage, although in cold weather your leaves may stop growing. They will carry on again once the temperatures rise.
