Think you can't plant a garden in November? If you live in a milder part of the country, you can! Cold-weather gardening is fun, and a great way to boost your diet with high-nutrient foods, to boot.
There are a number of hardy salad greens that can handle the cold. (Here, we're defining "cold" as staying mostly above freezing during the day.) When you're looking at seeds, look for greens where the instructions state they can be planted in spring before the last frost date. Some to consider: Ruby, Salad Bowl, Red Sails, Lolla Rossa, and Buttercrunch. And as their names suggest, you can't go wrong with Winter Marvel, North Pole, and Arctic King.
While you can plant seeds separately, we've had great success in mixing our favourite seeds together and planting them in our very own customized mesclun blend. Just mix the seeds together, then scatter them on bare soil more thickly than you normally would. Make your rows about a foot and a half wide for easy harvesting. When you harvest, pick only as many outer leaves as you need right away.
Kale is another great cold-weather crop. Choose several varieties so that you can enjoy a diverse range of tastes and textures. Similarly, Swiss chard is another vitamin-rich must-have, and you don't have to limit yourself to the green end of the spectrum. Varieties like Bright Lights cross the rainbow from green to pink, red, and orange.
You don't have to limit yourself to greens. Carrots can be grown and harvested well into the winter. If the weather turns cold, cover the plants with natural mulch and you can continue to enjoy them for weeks.
Similarly, radishes and beets (best enjoyed while they're still small) are fast-growing crops that do well under mulch. Sow seeds once a week for a few weeks and enjoy an extended harvest that can take you right into spring.
