What Vegetables to Plant in Fall: Quick Crops and Overwinterers

Vegetables worth planting in fall belong to three groups: quick crops such as radishes, lettuce, rocket and spinach that mature before hard frost; hardy greens like kale, chard and winter lettuces that keep producing through cool weather; and overwintering crops such as garlic, onion sets and broad beans that go in now and are harvested the following year. What you can sow depends on how many growing weeks remain before your first frost.

Start with your first frost date

Look up the average first frost for your area, then count backwards. Seed packets list the days to maturity; add a couple of extra weeks, because growth slows as days shorten. If the total fits between today and the frost, the crop is worth sowing. If it does not, choose something faster or one that is happy to overwinter.

Three groups of fall vegetables

Group	Examples	When you eat them
Quick crops	Radishes, rocket, baby spinach, loose-leaf lettuce, Asian greens	Within weeks, before hard frost
Hardy greens	Kale, chard, lamb's lettuce, winter purslane, spring cabbage	Through autumn and into winter, depending on climate
Overwinterers	Garlic, onion sets, shallots, broad beans, hardy peas	Late spring and early summer

Quick crops

These are the gap-fillers for beds cleared of summer tomatoes and beans. Sow little and often, a short row every week or two, so you are not faced with a glut. Radishes and rocket are among the fastest; loose-leaf lettuces can be picked a few leaves at a time rather than as whole heads. Cool weather actually suits many of them, as they are less likely to bolt than in summer heat.

Hardy greens

Kale and chard planted as young plants in early autumn will keep giving leaves for months in many gardens, and some say frost sweetens their flavour. Lamb's lettuce and winter purslane are small, tough salad plants worth trying if you want something fresh to pick in midwinter. A cloche or a sheet of fleece extends the season further in colder spots.

Overwinterers

These crops do most of their growing next spring but need to be planted in the cool months. Garlic is the classic example, and our guide to planting garlic in autumn walks through it clove by clove. Onion sets and shallots follow a similar routine. Broad beans sown in autumn tend to crop earlier than spring-sown ones in mild areas, though in very cold regions spring sowing is the safer choice.

Preparing beds after summer crops

1. Clear spent plants. Compost healthy foliage; bin anything that looked diseased.
2. Loosen the surface. A fork through the top few centimetres is enough; there is no need to dig deeply.
3. Feed the soil lightly. A layer of compost or leaf mold improves structure without pushing soft growth that frost will damage. Here is how to turn fallen leaves into leaf mold for next year's beds.
4. Water before sowing if late summer has been dry, then sow into the moist soil.
5. Protect seedlings from slugs and birds, which become very active in damp autumn weather.

Containers and small spaces

A trough or a few deep pots by the back door can keep you in salad well into autumn. Rocket, baby spinach, radishes and loose-leaf lettuces all do well in containers. Move pots against a sunny wall as the nights get colder, and bring the most tender ones into an unheated porch if a hard frost is forecast.

Mistakes that waste a fall sowing

• Sowing too late. Seeds that germinate just before frost rarely reach a useful size.
• Overfeeding. Lush, soft growth is easily damaged by cold.
• Ignoring drainage. Winter wet harms overwintering crops more than cold does.
• Planting everything at once. Staggered sowings give a steadier supply.

Flowers belong in the plan too

The same cool weeks are perfect for spring bulbs. If you are already kneeling in the beds, set aside a corner for colour and read our guide on when to plant tulip bulbs. A few flowers near the vegetables also bring pollinators in early spring, just as the overwintering crops begin to grow again.

Quick answers

Is it too late to plant vegetables in October?

Not necessarily. In many temperate gardens, garlic, onion sets and broad beans can still go in, along with fast salads under cover. In colder regions, the overwinterers are the safest bet.

Can I grow carrots in fall?

In mild areas, an early autumn sowing of a quick variety can produce small roots before winter, especially with a cloche. In colder places, it is usually better to wait for spring.

Do I need a greenhouse?

No. A greenhouse helps, but cloches, fleece and a sheltered wall extend the season enough for most fall crops.
