How to Plant a Fall Garden

There’s something so invigorating about getting my hands dirty in the garden. It’s become a part of my (almost) daily routine and the kids love helping too. Not only does it help reduce stress and improve the immune system, but I get tasty, healthy veggies too. Gardening doesn’t have to be relegated to summer crops though. Here’s how to extend your growing season with fall gardening!

Growing Summer Crops

When you think of a veggie garden you likely picture watering zucchini and cucumbers in the summer heat. Seeds get their start in late spring depending on your climate and what’s growing. And then by autumn, after all that summer squash has turned into zucchini bread, it’s time to call it quits.

You don’t have to wait until next year to grow more plants though! Certain veggies and herbs will also grow into the cool seasons of fall and winter.

Benefits of a Fall Vegetable Garden

Our family tries to eat seasonally as much as possible. This means cold slices of watermelon in the summer heat and pumpkin pie in October. There are some plants that grow well (or even better) in cooler weather. For example, spinach grows great in the early spring and fall. Once summer hits though, it can bolt and become practically inedible.

Fall gardening certainly has its benefits. In the summer I try to tend my vegetable garden in the early morning to avoid the heat. Fall crops grown in cooler temperatures don’t have that problem. They also experience fewer pests and weeds than summer season vegetables. Not only do certain plants grow better in cooler weather, but they taste better too.

Veggies like Brussels sprouts and kale produce more sugars after a frost. The result is sweeter vegetables. Dandelions are another plant that’s sweeter in the fall months, which is an ideal time to harvest them for dandelion root tea.

List of Plants to Grow in a Fall Garden

If you want to start a fall garden, the first step is to decide what you want to (and can) grow. You’ll want to pick plants that have a shorter growing season or are specifically listed as fall vegetables. The best vegetables are frost-tolerant and stand up to colder weather. Certain plants, like spinach, do well with a fall planting and can overwinter.

Here are some plants that do well in a fall garden:

Beets
Radishes
Brussel sprouts
Collards
Swiss chard (protect from frost)
Kale
Turnips
Arugula
Spinach
Bush beans (will need grown before or protected from frost)
Mustard greens
Lettuce
Carrots
Parsnips
Broccoli
Kohlrabi
Asian greens
Peas

Herbs and Flowers for a Fall Garden

Herbs not only make for tasty dishes, but they’re also good companion plants for your veggies. You’ll find basil nestled in between my tomato plants and nasturtiums bordering my squash. Some herbs and flowers have a short growing season, but some will last in cool weather.

Another tip is to plant your herb garden in pots so they can come inside for the coldest months. Herbs that are annuals in some climates can be grown as perennials with a little care. Many pollinators rely on these plants to give them the nutrients they need before winter migration or hibernation.

Here are some herbs that grow well in a fall garden:

Parsley
Chervil
Rosemary
Sage
Chives
Thyme
Mint
Lavender
Cilantro
Marjoram

Flowers:

Nasturtium
Calendula
Marigold
Joe Pye Weed (good for pollinators)
Black Cohosh
New England Aster

When to Start Seeds For a Fall Garden

When you start seeds and your planting dates depends on your USDA hardiness zone and first frost dates. You can look up your frost dates here. You’ll also want to add an extra 2 weeks to the grow time since plants mature slower in cooler weather. For example, if your seed package says the plant is ready for harvest in 60 days, expect it to take closer to 74.

Some seeds can be started indoors and then transplanted. Examples include bush beans and lettuce. Others can be sown directly in the ground (like root veggies). By starting the plants indoors you can have the summer veggies in the ground while you get a head start on the fall ones. Transplants should go into the ground in late summer or early fall for a fall harvest.

This is a really handy chart that tells you exactly when to plant different veggies for a fall garden harvest.

Rotate Crops For Healthier Plants

It’s also a good idea to rotate your plant families so you’re not planting the same thing in the same soil plot year after year. This depletes nutrients in the soil and causes poor plant growth. Here’s more on why. If you planted tomatoes in a certain garden bed for the summer (a nightshade), you could grow bush beans (legumes) there for the fall.

Grow For Even Longer

There are ways to extend your growing season even longer (especially if you live in an area with short summers). Cold frames and row covers can insulate plants from cold weather or a light frost. And if you’re lucky enough to have a greenhouse, these work even better to extend harvest well into winter.

Cold frames are an economical way to insulate plants and work as a mini greenhouse. They’re great for smaller plants. For larger spaces, row covers can be a better option. The ones with heavier fabric can increase the temperature by up to 10 degrees Fahrenheit.
