14 Foods You Can Grow In Containers Indoors Throughout The Year

Estimated reading time: 12 minutes

Once you’ve started growing some of your own food, it’s hard to kick the habit. But what can you do when your region is experiencing frigid nighttime temperatures or your garden beds are covered in snow? The answer is to take up indoor gardening.

Many plants adapt well to indoor spaces – even small environments. You probably already keep your home at a comfortable temperature for them, and pests are not as much of a problem as outdoors. If you monitor the nutrients and drainage of your potting soil, water sensibly, and provide plenty of light, you can maintain an indoor food garden all year round.

Here are some of the best choices for plants to grow indoors in containers throughout the year.

1. Microgreens

Let’s begin with an easy one. You can grow a thriving microgreen garden on a sunny kitchen windowsill all year long.

Since you’re harvesting microgreens as seedlings, shallow pots and trays work well. Scatter your seeds in about two inches of moist, peat-based soil. Keep the soil moist; you should see some sprouting in a few days.

You can start harvesting when the seedlings are about two inches tall and have two sets of true leaves. Seed to harvest time is about 14 days. Try planting a mix of seeds from various herbs and greens, including Swiss chard, radishes, beets, kale, and basil. Here’s more on growing microgreens at home.

2. Herbs

Herbs are another excellent option for all-year indoor growing. They are easy to grow and don’t require much space. Plus, once you’ve grown accustomed to using fresh herbs in your recipes, stopping isn’t easy.

Many herbs, including rosemary, basil, oregano, parsley, thyme, and mint, grow quickly under the right conditions. Those conditions include plenty of direct sunlight and moist soil, but not too wet.

You also have to be careful not to over-harvest your herbs. You can snip herbs once they’ve reached about six inches in height, but take care not to cut more than a couple of inches at a time. Here’s more on growing herbs indoors.

3. Leafy greens

Lettuce, spinach, Swiss chard, kale, arugula, sorrel, and mustard greens are among your many indoor garden options. Baby varieties of leafy greens have shallow roots and grow quickly.

One of the advantages of growing these leafy greens indoors is that you can harvest as many or as few outer leaves as you like, allowing the center to continue growing.

Use a container that is two to four inches in depth and fill it with well-draining soil. After sowing, keep the seeds moist, and germination will appear in about a week. You can find more on growing leafy greens here.

4. Scallions

Also called green onions and bunching onions, scallions are perennial plants. That means you can keep harvesting the leafy green parts without replanting. And here’s a bonus – you don’t even need seeds to grow scallions indoors.

Soon after you place a bunch of scallions in a container filled with about an inch of water, you’ll notice thin, white roots forming. When the roots reach a couple of inches in length, move the bunch to a shallow container filled with loamy, well-draining soil to continue growth.

As you harvest the green tops, be sure to leave at least an inch of the stem for regrowth. Check out this article for more on growing scallions in containers.

5. Garlic greens

If you like the idea of growing perennials in your indoor food garden, garlic is another great choice. As with scallions, if you don’t harvest the bulb, you can keep growing tasty garlic greens all year round.

You also don’t need seeds to grow garlic. Plant garlic cloves two inches apart and two inches of soil. You should be able to harvest some greens within 21 days or when the greens are eight or more inches tall.

Garlic greens have a taste that is a bit milder than garlic and stronger than scallions. Read more on garlic greens, sometimes called garlic scapes, in indoor containers here.

6. Radishes

Radishes are satisfying to grow indoors because they grow quickly and do not need much space. You’ll need to plant seeds in a container of at least six inches of well-drained, loose soil.

Radishes sprout within a week or less, and you harvest this root vegetable in 30 to 40 days. You also can eat the radish greens, if you like.

For radishes all year long, plant them in stages. This article gives you the details you need to know to grow radishes indoors.

7. Beets

Like some of the other veggies on this list, you can grow beets for their greens or their roots. Beet greens look and taste like their cousin plant, Swiss chard. Baby beets, which go from seed to harvest in 40 days, are an excellent choice for indoor growing.

After planting beet seeds, you’ll need to thin the multiple seedlings that sprout from a single seed. You can consume the tasty thinned seedlings as microgreens. You’ll find tips for indoor beet growing here.

8. Carrots

For indoor container growing, baby carrots fit the bill in many ways. They are easy to grow, mature quickly, and don’t require as much space as regular carrots. You can go from seed to harvest in just 40 days for baby carrots.

Plant your seeds in loose, well-draining soil, lightly covering them with damp peat moss. Keep the soil moist, and you should see germination within two weeks. Here is more on how to grow and harvest carrots in indoor containers.

9. Bush bean

 Bush beans are compact plants that can produce a sizeable harvest in a short time. After planting your seeds, you should see sprouts within two weeks. You’ll be able to harvest in six to eight weeks.

Beans like moist soil conditions and abundant light. However, they can develop root rot if their roots are left in standing water for too long, they can rot. Here’s the information you need to know for container bush bean success.

10. Peas

Peas are another option for indoor container growing. For best results, consider snap peas, snow peas, or dwarf peas. They all do well in containers and don’t require much attention as long as they have adequate light, well-draining soil, and biweekly watering.

As the plants grow, you can snip the pea shoots for salads and then harvest the pea pods when they are ready. You can sow peas every few weeks for an ongoing harvest. Here’s what you need to grow peas indoors in containers.

11. Tomatoes

 Some tomato varieties adapt well to indoor containers, and you can grow certain ones in hanging baskets to take advantage of vertical space.

Look for compact varieties with “bush” or “patio” labels. These plants produce cherry, grape, Roma, and other small fruits. Indoor tomato plants tend to have weaker stems than outdoor tomato plants, so you may need to stake or trellis them for best results.

Tomatoes require a minimum of 10 hours of light each day. They prefer loamy, well-drained soil. You can expect a seed-to-harvest time of 50 to 65 days. Check out this article for more info on growing tomatoes indoors.

12. Peppers

With their interesting textures and bold colors, hot peppers are an attractive choice for indoor container gardening. Use containers that are at least eight inches in depth and plan for 10 hours of light exposure. Peppers prefer well-draining soil.

Depending on the variety, germination typically occurs between two and three weeks, with harvesting within 60 to 90 days. Here’s a video that shows you how to grow peppers indoors in containers all year.

13. Strawberries

Let’s not forget fruits on this list. You can grow and harvest strawberries in indoor pots and hanging baskets. Alpine strawberries are an excellent choice.

Sow alpine strawberry seeds in moist, well-draining soil. Place containers in a south-facing window that gets eight to ten hours of sun each day. Or, use a grow light for about 12 each day.

In the outdoor garden, bees distribute pollen, but indoors, you’ll need to help the process along. Use a small, soft paintbrush to spread pollen across the flower from the male to the female parts. This video shows you how.

14. Citrus trees

The next time you visit your local nursery, check out the compact citrus trees designed for indoor growing. The Meyer lemon tree, which produces fruit that tastes like a cross between a lemon and a Mandarin orange, is a good choice

These trees produce lovely flowers, but they do like things warm and humid. If your home gets dry, you may need to mist the leaves once or twice a day. Running a humidifier is another option.

As you learned with strawberries (above), you’ll need to pollinate the fruit by hand. Here’s more on growing Meyer lemon trees indoors.

Tips for indoor container growing

Here are some general tips for growing vegetables and fruits indoors.

• Grow vegetables in containers with ample drainage openings and are the correct size for the plant you’re growing.
• Use a quality potting mix. These mixes usually have vermiculite or perlite as ingredients, which allow for better drainage.
• Provide adequate air circulation to prevent fungal and root problems.
• Provide access to direct sunlight and consider some type of supplemental lighting.
• Aim for a home temperature range of 60 to 75 degrees F.
• Learn about each plant’s nutritional needs and apply fertilizer accordingly.
• Consider grouping plants with similar watering, light, and humidity needs together.
• Water with care, paying attention to the soil. The best way to tell if water is needed is to feel if the soil is dry one to two inches below the surface.

Like outdoor gardening, successful indoor gardening can be a matter of trial and error. Keep track of what works and what doesn’t. Make necessary adjustments, and try again.
