1. Turnips
Choose a quick growing variety and you'll be sure to get a wonderful harvest of clean white roots. Turnips grow quick, easy and relatively trouble free and is a perfect crop when any beds are left bare from summer's harvest.
2. Broad Beans
Broad Windsor beans are the best for autumn planting and can sown from September until early November for harvesting a month earlier than a spring sown crop. Another perk of sowing broad beans in the winter is the plants protect the soil that would normally be exposed to wet winter weather. Think of this planting similar to a "cover crop". Don't forget to stake your plants to protect from any harsh winds.
3. Onions
Growing onions from sets anytime in autumn will produce an earlier harvest the following spring. This is generally not recommended, however, if your garden is prone to lots of water during the winter months. Plant onion sets and shallots in Sept/Oct for harvesting around May.
4. Kale
Kale is very easy to grow, highly nutritious and, tastes delicious when cooked or even raw in salads. It also can survive the harshest winter. If your plants are large enough you will get some beautiful winter greens but the main reward will be when the plants get back into action once spring arrives and there is little else in the garden.
5. Radish
Radishes grow quickly and you can harvest them only about 4 weeks after sowing. The trick is to get them quick while they're still small for a fresh peppery bite.
6. Cabbage
Spring Cabbage plants are sown during autumn for a harvest of tasty heads the following spring. Just keep and eye out for slugs, they can still wipe out your new seedlings even during winter-time.
7. Kohlrabi
It’s fast growing which makes it a good choice for an autumn crop. Growing inside in a tunnel is ideal if you have harsh winters.
8. Mustard Greens
These grow much more successfully in cooler temperatures. Mustards tend to be frost hardy and while they don’t enjoy being frozen they certainly tolerate it well.
9. Garlic
Just plant the a clove in the ground and without much intervention you should end up with a full bulb the following autumn. You can also plant garlic in the spring, however the bulbs won't be as large if you had started them in the fall.
10. Swiss Chard
Some people do not care for the slightly bitter taste of chard, but this is where Autumn and overwinter planting are an advantage. Chard is less bitter in the colder months of the year because the plant puts out more sugars when temperatures are cooler.
