Ready to beat the summer sun and hit the garden? Here are 19 vegetables to plant in September.
Best September Vegetables to Plant
What vegetables will thrive at particular times depends on where you’re in the world. In the United States, a system of zones can help you learn the best vegetables to plant in September in your area. However, here are 19 vegetables that are usually a safe bet for September sowing.
Beets
Beets can be harvested in both fall and winter if you’re looking for a bountiful harvest season. For a fall harvest, make sure to plant them at the end of summer. For winter, you can prolong this until fall. Unless you live in an area with warm winters, planting your beets anywhere from four to nine weeks before the season’s first frost is best. They can be harvested in around eight weeks after you first plant them. You can eat both the tops and roots of the beet plant. When you think of this plant, it’s most common to think of the beetroot: the small, purple or red bulb that the roots extend from. No matter which part of the plant you decide to enjoy, beets pack a powerful, nutritional punch. They’re also easy to can or otherwise preserve for year-long use.
Broccoli
Broccoli is a fairly hardy fall-time vegetable. As a result, they’re one of the best vegetables to plant in September. You can begin planting them in late summer into the beginning of fall, giving you time to figure out exactly how to run your garden. This is good because broccoli prefers loam soil, which you may need time to prepare. After your September sow season, however, you can expect to harvest most varieties of broccoli within eight to nine weeks. The broccoli that you eat is actually a juvenile flower bud. A member of the cabbage family, you can eat the flowering head and stalks of the broccoli plant, and you can even eat some of the smaller leaves you may find in your harvest. Broccoli is high in the daily vitamins and minerals needed for health, and they also offer a large amount of protein compared to other vegetables.
Brussels Sprouts
Compared to the other vegetables on this list so far, Brussels sprouts require a long growing period. They thrive during cool weather and actually taste better when they’ve survived a frost or two. It takes around 100 days to enjoy your labor’s fruits (or vegetables) from planting to harvest. This makes them the perfect vegetable to plant in September for a rich winter harvest. Brussels sprouts are a type of cabbage, and they’re related to broccoli, kale, and kohlrabi. Along with other crunchy vegetables, they’re one of the best ways to fight and prevent certain diseases and cancers naturally.
Carrots
The rule of thumb for carrots is that they can be sowed from the spring equinox in the middle of March to the fall equinox in the middle of September. In fact, you can sow a row every three or so weeks in order to have a carrot harvest year-round. Like Brussels sprouts, they have a long growing season of up to four months. By planting at least one row in September, you’ll have a carrot harvest just in time for your holiday dinners. Carrots are rich in vitamins, minerals, fiber, and even antioxidants. They support gut health, can reduce the risk of certain diseases, and even help boost your immune system. However, it’s important not to eat more than one to two carrots daily. Any more than that, and you risk it turning orange due to an excessive amount of beta carotene, which gives the carrot its color.
Cauliflower
Typically, cauliflower is harvested in September. However, it’s also possible to sow cauliflower in some areas in September for a winter harvest. Just make sure to check the temperature of the soil: it should be between 65°F and 75°F. You’ll also want to ensure that winters in your area are mild with little to no frost. If you’re willing to sacrifice the size of your crop, you can also grow cauliflower inside! It takes around 80 days to harvest your cauliflower. Cauliflower is often used as a substitute for meat in many recipes. However, whether it’s the star of the dish or a side, this September vegetable is rich in nutrients. It’s high in fiber and antioxidants and can easily be incorporated into a meal.
Celery
It takes around four months to grow celery. As a result, if you’re looking for a winter harvest, celery is one of the most popular vegetables to plant in September. You’ll want to ensure you start your seeds in advance so they can grow before the first frost date. Celery can also be grown from kitchen scrapes and kept indoors year-round. Celery is rich in fiber and can be used to improve gut health and digestion. Due to the structure of its crunchy, fibrous stalks, it’s also good for dental health. That’s right – celery can act like a natural floss!
Fava beans
You can grow fava beans in three main months: September, October, and March. Like many beans, fava beans will reach maturity at one date but continue growing. So, although fava beans will reach maturity in about 80 days, you can harvest them up until about March for a September crop. For beginners, fava beans may be one of the best vegetables to plant in September due to their hardiness. Although fava beans look similar to lima beans, they’re not the same. Fava beans have a milder, earthy taste that many people relate to nuts or cheese, and they’re high in protein and many other necessary nutrients.
Head Lettuce
Like many other leafy vegetables, head lettuce is a cool weather crop, which means it grows best in the spring and fall. To enjoy fresh ingredients into the winter, you can plant head lettuce well into September, around the first three weeks. Most head lettuce reaches maturity within a month to three months, but you can harvest it whenever it reaches the desired size. Head lettuce is also known as iceberg lettuce or crisphead lettuce. It’s not as nutrient-dense as leaf lettuce, but it offers a nice texture and sweetness to elevate your day-to-day meals and snacks.
Kale
You don’t just have to sow kale in September; it can also thrive in May, June, and October. Kale is one of the hardest vegetables to plant in September, making them a great choice for diverse regions. Not only are they resistant to frost but even snow! As a result, planting them often during September and other cool months can lead to a large harvest throughout the year. It takes up to 95 days for your kale harvest to be ready. Kale is also known as leaf cabbage. They’re a leafy vegetable with a unique texture, making them a popular addition to sandwiches and salads.
Kohlrabi
It takes around 55 days for kohlrabi to mature for harvesting. They’re hardy enough to survive mild temperatures, making them a great addition to your September garden. You’ll want to plan your harvest for a week or two after the first frost of the fall season. As a result, timing is everything when starting and sowing your kohlrabi. You can start your seeds indoors up to six weeks early if needed. Kohlrabi is an interesting vegetable, and they look similar to a turnip, which has earned them the names German turnip and turnip cabbage. It can be eaten raw or cooked, and it’s popular in various dishes.
Leeks
The middle of September is the end of the leek sowing season, and this is the best time to finish the year strong with a healthy harvest of leeks! Leeks have one of the longest maturity times out of all of the crops on this list. It can take up to 150 days, or around 5 months, for your leeks to reach full maturity. Leeks are related to the onion, although they have a much milder and sweeter taste. They’re often used as a compliment to potatoes. Although it is common to only look at the white section of leeks, the leaves offer benefits when cooked correctly.
Leaf Lettuce
Leaf lettuce is related to head lettuce. However, rather than growing in a tightly knit rosette, leaf lettuce grows more freely, with bushels of leaves. They’re a fairly hardy plant and the perfect vegetable to plant in September. They can be harvested within a month of sowing, making them a quick crop to squeeze in at the end of the sowing season. Make sure to sow your last batch of leaf lettuce when there’s still plenty of time for them to grow and mature before the first frost of the fall season. Leaf lettuce is one of the most versatile fall vegetables, and it’s great in salads, sandwiches, and wraps. The variations allow you to grow the perfect ingredient for different flavored meals.
Mustard greens
Although they’re similar, mustard greens aren’t the same as collards. One of the main differences is that you want to plant collards in early spring or late summer, while mustard greens can be planted in September. They’re fast growers, and depending on the size of leaves you want to harvest, you can pick your mustard greens between four and eight weeks! Mustard greens can be eaten raw or cooked. They’re popular in salads for their texture and flavor. However, some people may find the flavor too strong, making cooking them a popular option as well. When it comes to cooking, most people choose to steam or stir-fry mustard greens, although the possibilities are endless.
Onions
There are several varieties of onions. For more varieties, the best time to grow this popular vegetable is late summer to early fall. In fact, because of how they grow, they’re considered one of the best vegetables to plant in September. This gives the onions ample time to reach their full potential. Because they’re root vegetables, like potatoes, they’re hardy and can survive colder temperatures than other plants. Onions are also especially easy to grow from kitchen scraps, which helps create an eco-friendly and low-cost garden that’s easy to start. You can grow them from scraps indoors and have an onion harvest within about 120 days or four months.
Parsley
Herbs like parsley are a subset of vegetables. Because parsley, in particular, is a cool-weather herb, they thrive in the latter months of the year. This includes September. However, they have a rather long growing season, so don’t expect a harvest within the same year! Instead, look to May and June for your first parsley harvest. Because they’re annuals, you will need to plant them again once September rolls back around. Parsley is a popular ingredient and garnish for many dishes. Elevate your summer cooking with this powerful herb by taking advantage of their cool-weather growing season this September.
Peas
If you’re not quite ready to start your garden for the season and you’re looking for a vegetable to plant at the end of September, look no further than peas. Peas can be sowed through September to November, making them a great addition to a last-minute fall garden. Sowing around this time will lead to an early spring harvest. Please pay attention to the variety in growing peas in the fall. While some peas can thrive when planted in September, some may need earlier sow times.
Potatoes
Potatoes are one of the easiest vegetables to grow, and they’re also a popular vegetable to plant in September due to their lack of maintenance and overall hardiness. Although they’re typically planted in the spring, they can also thrive in a fall garden. In fact, planting them in September will give them plenty of time to grow and mature in time for the holidays. Like onions and many other vegetables on this list, potatoes can be grown from kitchen scraps.
Radishes
To grow radishes in the fall, you’ll need to plant them earlier in September. However, they can thrive indoors all year long. They’re one of the fastest growing plants on this list, with some being ready in as soon as three weeks. That’s right, as long as they’re of usable size, you can harvest radishes. It’s recommended to harvest them sooner rather than later because too much time underground can cause a decline in their taste and texture.
Rutabagas
Rutabagas are considered a cross between a turnip and a cabbage. They can be eaten raw or cooked, although the flavor can vary greatly between the two options. Like radishes, you can sow them in September and then harvest them until they’re of a usable size.
