October Isn’t Too Late to Plant – These 10 Vegetables Deliver Harvests Through Fall and Beyond
October feels late for sowing, but plenty of crops are just getting started. Discover what to plant now, with advice on zones and timing.
Plenty of gardeners treat October as cleanup month. The tomato cages come down and the squash vines get yanked, then the beds sit bare until spring. That ground still has plenty of use left in it, though. Cooler nights and a lower sun happen to suit a whole group of crops that bolt or turn bitter in summer heat, and quite a few can go in this month for harvests running from late fall into next spring.
Timing is where it gets tricky. Anyone starting a vegetable garden this late in the year still has options, but much depends on USDA zones (or your equivalent growing zone for non-Americans) and first frost dates. A gardener in mild zone 9 has months of planting weather ahead, while someone in cooler zone 5 might see the soil freeze solid by Thanksgiving – pretty different situations.
The solution is to choose crops that are suited to shorter days and chillier evenings. From leafy greens that thrive with fewer pests in fall to root vegetables that overwinter underground, and even hardy herbs that normally bolt in the high heat of summer. Plenty of options are available for anyone who wants to keep planting seeds in October and enjoy a home-grown seasonal bounty.
How USDA Zones Shape October Planting
One detail catches a lot of people off guard. USDA zones are built on average extreme winter lows, not frost dates, so two towns sharing a zone can see their first frost weeks apart – elevation and coastal influence skew things quite a bit. Zones still work as a rough guide to what can sit in the ground over winter. Frost dates tell when to stop sowing; zones hint at what survives after that.
Count back from the average first frost date using the days to maturity on the seed packet, then add a week or two. Growth slows as fall days shorten, and packet numbers usually assume summer conditions. Overwintering crops are a different story – they only need roots down before the soil freezes.
Cool-Season Vegetables to Sow in October
A few of these work across most of the country this month. Others only pay off where winters stay mild, so it helps to know the zone before buying seed.
1. Garlic
October is prime time for growing garlic, with cloves going in a few weeks before the ground freezes in zones 3–8. However, planting times for garlic vary slightly by region. Down in zones 9 and 10, there's no rush – November or December works fine.
Break the bulb apart and set individual cloves pointed end up, roughly 2 inches (5 cm) deep and 4–6 inches (10–15 cm) apart.
You can plant grocery store garlic, but it is usually a softneck variety grown in mild winters, and it can struggle in colder regions, unlike hardneck garlic types. A garden center or seed catalog is the better source – you can pick up a flavor sampler organic garlic bundle from Botanical Interests, which includes two hardneck varieties and elephant garlic.
Up north, pile on straw mulch once the soil cools – 4–6 inches (10–15 cm) is typical. Freeze-thaw cycles can heave bare cloves right out of the ground otherwise. Harvest comes next summer as the lower leaves brown.
2. Spinach
Spinach sown in early October across zones 5–7 often overwinters as small rosettes. Come spring, those plants are usually ready to cut weeks before anything sown in March. Zones 8–10 get the easier deal, with steady cutting straight through winter.
Bloomsdale Long Standing, available from Eden Brothers, is a lovely, rich heirloom spinach that performs well with fall planting, while Noble Giant produces huge sweet leaves that do not turn bitter as temperatures drop.
Plant seed ½ inch (1 cm) deep. Germination tends to suffer in warm soil, roughly 75°F (24°C) and up, and a warm spell in early October can push beds into that range. In colder spots, row covers, like these Agfabric ones on Amazon, or loose straw help young plants through hard freezes.
3. Radishes
Small round radishes rank among the quickest crops around, going from seed to harvest in three to four weeks. That speed makes them a safe October sowing in zones 6–10, while zone 5 gardeners can sometimes squeeze in a crop during the first week or so.
The big winter types are another matter – most need closer to two months, so they're better started in late summer outside the South.
If the idea of classic white and red radishes bores you, then try black radishes. This resilient variety thrives in cool seasons across USDA Zones 3–9 when planted in well-draining soil and full sun. Pick up a pack of Round Black Spanish Radish Seeds at Botanical Interests.
When planting radishes, sow seed ½ inch (1 cm) deep. Crowded radishes tend to put everything into leaves, so thin seedlings to 1–2 inches (2.5–5 cm) apart.
4. Lettuce
Lettuce tends to get filed under spring crops. Through much of zones 8–10, though, October is when its best stretch begins. Loose-leaf types may be ready to cut in six or seven weeks, and light frost rarely does much damage. A hard freeze is another matter – expect mushy leaves.
Zones 6 and 7 can pull it off with shelter – a cold frame similar to the Zenport folding cold frame at Lowe's can trap enough daytime warmth to keep leaves coming into early winter. Crack the lid on sunny days, though. It gets hot in there fast.
There are so many varieties of lettuce to choose from, and so it's worth getting a mix pack of seeds, like this Survival Seeds 10 Heirloom Lettuces Collection, from Amazon. Many can be harvested as cut-and-come-again.
Scatter seed thinly with barely any soil on top; often lettuces germinate better when a little light reaches them.
5. Fava Beans
Snap beans rarely survive a frost. Fava beans are a different animal, a cool-season legume that can take a fair amount of cold. Gardeners in zones 8–10 can sow them anytime from October to December, and growth crawls along all winter before pods show up in spring. Zone 7 is more of a gamble – seed labeled for overwintering helps, but a rough winter can still set plants back.
Windsor fava beans from Botanical Interests are tasty and look pretty in beds. You can eat the young pods like snap peas.
Plant 1–2 inches (2.5–5 cm) deep with about 6 inches (15 cm) between seeds. By spring, the stems may be tall enough to need a stake. After the last pods come off, cut plants at the soil line and leave the roots where they are. They return some nitrogen to the bed for whatever goes in next.
6. Carrots
This one mostly belongs to Southern gardeners. October-sown carrots in zones 8–10 typically need two to three months to size up, and a carrot pulled in January often tastes noticeably sweeter than a summer one. Cold soil pushes roots to turn some starch into sugar. Farther north, there usually isn't enough time before the ground freezes.
Organo Republic sells a 10 Unique Carrot Seeds Variety Pack on Amazon, which offers all the flavor variety you could want.
Seed goes in ¼ inch (6 mm) deep, and it's slow – sometimes two weeks or more to sprout. Keeping that top layer moist is honestly the hard part. A strip of burlap laid over the row helps, as long as it comes off the moment seedlings appear.
7. Herbs
From parsley to cilantro, starting an herb garden is a great way to fill your life with fragrance and flavor in the months to come. Get started with Home Grown's 15-Variety Herb Pack on Amazon; if you're worried about cooler temperatures, you can always keep them in pots on a sunny windowsill. Most, however, should cope in zones 5–10, making them ideal crops to plant in October.
October is best for planting cool-season herbs such as parsley, cilantro, chives, dill, and chervil, which can handle lower temperatures and may keep producing into fall. You can also plant hardy perennial herbs like thyme, sage, oregano, and mint in many areas while the soil is still workable. Some herbs will need winter protection in colder regions.
8. Snow Peas
Snow peas are cool-season vegetables that are quite frost-hardy, but don’t worry; they require no more work than growing other varieties of peas, making them one of our favorite low-maintenance vegetables to plant in October (particularly if you’re based in USDA zones 8 and 9).
Just make sure you get them in the ground about 6 to 8 weeks before your area's first fall frost to allow the roots to establish before a hard freeze – and mulch well, too. We’re fans of the Dwarf Grey Sugar heirloom snow peas, available from Eden Brothers.
Plant snow pea seeds directly into loose, well-drained soil about 1 inch deep and 2 inches apart, ideally beside a trellis or other support for the vines to climb. Choose a spot with full sun and keep the soil consistently moist. Harvest the flat pods once they reach a useful size, before the peas inside begin to swell.
9. Shallots
One of the easiest vegetables to plant in October, shallots are very similar to garlic in lots of ways; all you need to do is sow sets or seeds, like the sweet, mild Zebrune Shallots from Botanical Interests, in loose, well-drained soil amended with organic matter, then wait until June or July to harvest.
Fall planting is generally most successful in USDA Zones 4–10, although gardeners in colder Zones 3–5 may need to add a thick layer of mulch or plant in raised beds for extra drainage and protection. In the coldest areas, spring planting may be more reliable.
10. Beets
Of course, beets are on our list of vegetables to plant in October; these tasty red crops can be grown all winter long in many southern states (though you’ll need a soil temperature of at least 40°F in the north).
Sow beet seeds directly into loose, well-drained soil around ½ inch deep, spacing them roughly 1–2 inches apart. Once seedlings emerge, thin them so the remaining plants have room to swell, or harvest the thinnings as baby greens. In warmer Zones 7–10, October sowings can provide a steady winter crop, while gardeners in colder areas may need to use row cover or a cold frame.
Most will be ready for harvesting after seven to eight weeks, although beet greens can be picked earlier. And, if you want to up the ante, try something like Organo Republic's 10 Rare Beet Seeds Variety Pack from Walmart; it should make for a truly spectacular display!
