6 Tips for Growing Winter Salad Greens
1. Prepare your soil – If you’re growing your winter salad greens outside, find a sheltered and sunny spot in your garden. Or choose large and narrow containers or pots for growing in a greenhouse or polytunnel. It’s important to choose a spot (or pot) with good drainage as seedlings can freeze if left in pools of water. Sift your soil into a fine grade if using your own compost, and add any necessary nutrients such as lime or potassium to make potting soil.
2. Sowing the seeds – The ideal time for sowing seeds is between early September and late November, depending on the first estimated frost date in your area. Sow your seeds in short and shallow rows, spaced as instructed on your seed packet. Cover with a thin layer of soil and water. If you have sown your seeds outside and a cold night is in the forecast, cover them with a fleece or cloches to protect them. For a continous supply of salad greens, sow seeds apporximately every 3 to 4 weeks.
3. Caring for your seedlings – Keep the soil moist but don’t let it get too wet, as the seedlings can die from the chill. Don’t water your winter salad greens in the evening or too early in the morning.
4. Thinning your greens – If you have sown ample seed, your beds or pots will have likely have too many seedlings trying to grow in them. You can thin them so that the ones you’ve left have ample growing space. Use the thinned baby greens in a salad!
5. Harvesting your greens – Your winter salad greens are ready for harvest when they are about 4 inches tall. Harvest the outer leaves, letting the smaller inner leaves form to full size.
