There’s something about the cooler autumn weather that just makes you want to get in the kitchen and cook a nice soup or stew or something.

Maybe it’s the fact that summer’s heat is finally over, or maybe it’s the delicious smell of pumpkin spice in the air. But whatever it is, there’s no denying that fall is one of the best times of year to cook up a storm.

And if you’re a gardener, fall is also the perfect time to start planning your next crop. That’s right, fall is the perfect time to start thinking about extending your vegetable garden into the cooler months. There are a variety of crops that will withstand cooler temperatures and sometimes even frost.

So let’s talk about how to grow a fall garden! and why grow a fall garden.

How to figure out your average first frost date

Before you plant any seeds for fall, make sure you know when your first average frost date is for your area.

  • Do a Google search for “Average first fall frost date in (insert your zip code here)” for an answer.
  • Now, calculate how many days are left before the average last frost date.
  • Next, note down the days to maturity of each seed you want to buy or sow for fall. If there aren’t enough days left this year, consider saving the seeds for next year instead. Or attempt winter sowing!

When you go to plant seeds for fall, make sure you’ll have enough time for each variety to mature and fruit before the frosts hit.

Some cold-hardy greens and veggies and withstand a bit of frost, so if you’re a couple of days or weeks off, my vote would be to plant them anyway.

How can you extend your vegetable garden into the cooler months?

While most people think of gardening as a summer activity, there are actually many ways to extend your garden into the cooler months.

  • One way to do this is by planting cool-weather crops like kale, spinach, and broccoli. These vegetables can tolerate colder temperatures and still produce a bountiful harvest.
  • Another way to extend your garden is by using row covers or cold frames. These structures provide protection from the elements, allowing you to extend your growing season by several weeks.
  • Don’t forget about less conventional methods like hydroponics and indoor gardening. These techniques can be used to grow delicious vegetables year-round, regardless of the weather outside.

What are some of the best fall garden crops to try growing?

While many people think of spring as the best time to start a garden, fall is actually an ideal time to plant many vegetables.

In fact, fall gardening can result in tastier and more nutritious crops, thanks to the cooler temperatures. Some of the best fall garden crops to try include leafy greens, root vegetables, and cold-hardy perennials.

  • Kale and spinach grow best when planted in the fall, as the cooler weather helps to improve their flavor.
  • Carrots also prefer cooler temperatures, and fall is the ideal time to plant them if you want sweet-tasting roots.
  • Potatoes are another fall crop that benefits from cooler weather; they tend to be larger and less drought-sensitive when grown in fall conditions.

So if you’re looking to try something new in your garden this year, consider planting some fall garden crops. You may be surprised by how much you enjoy the results.

I generally have a better harvest from my fall garden here in Colorado because the grasshoppers and the sunscald are crazy during summer.

What are some of the benefits of growing vegetables in the fall?

Many people think of spring as the best time to plant a garden, but fall can actually be an ideal time to grow vegetables.

For one thing, there is less pest pressure in the cooler months, which means that plants are less likely to be damaged by insects.

Additionally, fall gardens need less watering than those planted in the spring, since evaporation rates are lower. As a result, gardeners can save time and money by growing their vegetables in the fall.

In addition, the cooler temperatures of autumn can actually improve the flavor of some vegetables, such as cabbage and Brussels sprouts.

So if you’re looking for a bountiful harvest with minimal effort, consider planting a fall garden.

How can you prepare for a fall garden vegetable crop rotation?

Crop rotation is the practice of growing different types of plants in different areas of your garden from year to year. This helps to prevent nutrient depletion and reduce the risk of disease and pests.

When planning your rotation, it’s important to consider the following factors: the size of your garden, the climate, the type of soil, and the amount of sunlight each area receives.

Once you’ve taken these factors into account, you can start planning which crops to grow where. For example, if you have a small garden, you may want to consider growing leafy greens in one section and root vegetables in another.

Or, if you live in a warm climate, you may want to start your rotation with cool-season crops like broccoli and cabbage.

Once your summer garden starts taking off, think about starting seeds for the fall garden. Here in Colorado, I start many fall seeds indoors in late July through mid-August. Faster-maturing plants, like radishes, can be planted even later.

What are some of the most common pests and diseases to watch out for in a fall garden?

Powdery mildew

Powdery mildew is a fungal disease that thrives in cool, humid conditions. It appears as a white or gray powder on the leaves of affected plants and can quickly spread to other parts of the plant.

Unfortunately, there is no cure for powdery mildew once it has taken hold. The best way to prevent it is to water early in the day so that the leaves have time to dry before nightfall.

Root rot

Root rot is another problem that can affect plants in the fall. This fungal disease occurs when roots are constantly wet, causing them to rot away.

Gardeners can help prevent root rot by ensuring their plants have good drainage and by avoiding over-watering.

Late-season blight

Late-season blight is a fungal disease that affects tomatoes and potatoes. The first symptoms are small, dark spots on the leaves, which eventually turn brown and wither. Blight can also spread to the fruit of affected plants, causing it to rot.

To prevent late-season blight, gardeners should water early in the day and avoid wetting the leaves. They should also remove any affected leaves and dispose of them immediately.


Caterpillars, such as the cabbage looper and the tomato hornworm, can be a problem in the fall garden. These voracious eaters can quickly strip a plant of its leaves, causing serious damage.

Gardeners can prevent caterpillar damage by keeping an eye out for these pests and removing them by hand when they’re found.


Aphids are small, winged insects that feed on the sap of plants. They can cause serious damage by weakening the plant and transmitting diseases.

Aphids are most active in the spring and summer, but they can also be a problem in the fall. To prevent aphids from damaging your plants, try planting companion plants that attract beneficial predators, such as ladybugs.

There are also a few organic or homemade remedies for aphid infestations. One of them being the good ‘ol eco-friendly dish soap and water application. Neem oil is another popular organic pest control method for aphids – just be sure to dilute it according to the package directions so that you don’t burn your plants!

Slugs and snails

Slugs and snails are common problems in the fall garden. These slimy pests feed on leaves and can quickly damage a plant.

To prevent slug and snail damage, gardeners can try using traps or barriers. Copper tape is a popular barrier material, as slugs and snails will not enjoy crossing it and in many cases, they will avoid that area.

Another idea to tackle a slug problem is to plant a little plot just for them and don’t take any pest control measures on it whatsoever. Protect your main garden and allow the slugs to feast on their share to keep them away from your crops.

What are some tips for harvesting vegetables in the fall?

Fall is the perfect time to harvest many vegetables, including potatoes, carrots, cabbage, and Brussels sprouts.

Pay attention to the weather forecast and plan to harvest your vegetables before a hard frost hits. Eating freshly picked vegetables is one of the great joys of gardening, so don’t wait until it’s too late!

Here are a few tips to help you get the most out of your fall harvest:

  • Start by preparing your garden beds for the winter. Remove any remaining crops, and add a layer of mulch to protect the soil.
  • When harvesting root vegetables like potatoes and carrots, be sure to loosen the soil around the plant before pulling it up. This will make it easier to remove the roots without damaging them.
  • Harvest cabbage and Brussels sprouts when the heads are firm and compact. Cut the heads off at the stem, being careful not to damage the leaves.
  • Store your harvested vegetables in a cool, dark place. Root vegetables can be stored in a root cellar or basement, while cabbage and Brussels sprouts can be stored in the fridge.

How can you preserve your fall garden harvest?

Canning, freezing, and drying are all great ways to preserve your fall garden harvest. Canning is a particularly good choice for high-acid foods like tomatoes and fruits.

Freezing is a good option for most vegetables, and it preserves flavor better than canning. Drying is ideal for herbs, spices, and fruits. It’s also a good way to extend the life of perishable items like mushrooms. To get started, you’ll need some basic supplies.

  • For canning, you’ll need a large pot, jars, lids, and a jar lifter.
  • For freezing, you’ll need freezer bags and a sharpie.
  • And for drying, you’ll need an oven or dehydrator and some cheesecloth or towels.

With a little planning and effort, you can enjoy a bountiful fall harvest that will last long after the growing season is over.

What are some recipes that feature fall garden crops?

Pumpkins, squash, and apples are just a few of the delicious crops that come into season in the autumn months.

And what better way to enjoy these fresh-from-the-garden goodies than by whipping up some homemade recipes?

  • Baked pumpkin chips. Simply slice a small pumpkin into thin wedges, brush with olive oil, and sprinkle with salt and pepper. Then bake in a preheated oven until crispy.
  • Roasted acorn squash. Cut the squash into quarters, remove the seeds, and drizzle with maple syrup and melted butter. Roast in the oven until tender.
  • Baked apples are always a hit. Core several apples and stuff them with your favorite filling. We like a mix of brown sugar, cinnamon, and raisins. Bake in a glass baking dish until soft and bubbly. Serve warm with vanilla ice cream for a truly decadent dessert.
  • Pumpkin pie. A classic.
  • Roasted butternut squash soup. This soup is perfect for chilly evenings. Simply roast some butternut squash in the oven until it’s nice and soft, then blend it up with some chicken or veggie stock, onion, garlic, and spices. Top with a dollop of yogurt or cream and some chopped fresh herbs for extra deliciousness.
  • Winter squash pasta. I love using butternut squash or honeynut squash for this, but you could use most winter squashes including pumpkin for this. Squash pasta is in one of my favorite meals overall and I really encourage you to try it! My kids love it, too, which is a bonus.
  • Autumn salads. A great way to use up any leftover veggies. So many ways to go with this but you can’t beat a good salad. Add some quinoa in there or some beans for extra substance.

What else can I do to benefit my garden during fall?


As the weather cools and the leaves begin to fall, it’s important to take some steps to prepare your garden for winter.

  • You can start by cleaning up any dead leaves or debris, as this will help to prevent disease and pests. Dead leaves are perfect for composting, so make sure to do that for a soil boost next season!
  • Fall is a good time to fertilize your plants and add organic matter to the soil. This will help to ensure that they have the nutrients they need to survive the winter and thrive in the spring.
  • Be sure to water your plants and trees well before the first frost. This will help them to stay hydrated and prevent them from becoming damaged by the cold.
  • Explore the idea of planting cover crops for fall to enrich your soil.

TLDR; Why grow a fall garden?

Fall is a great time to start a vegetable garden. The weather is cool and the days are shorter, which means that plants won’t dry out as quickly.

Fall gardens also benefit from fewer pests and disease pressure. And, of course, fall vegetables are absolutely delicious! Cool-weather crops like kale, lettuce, cabbage, and even squash are at their peak in the fall, and they are versatile and easy to grow.
