Introduction:
As the winter months approach, gardeners often face the challenge of limited outdoor growing opportunities due to cold temperatures and frost. However, the solution lies right within your home – indoor winter gardening! With a little creativity and the right choice of vegetables, you can continue to enjoy the joys of gardening even when the snow blankets the ground outside. In this blog post, we’ll explore the five best vegetables to grow indoors during the winter, bringing fresh flavors and a touch of greenery to your home all season long.

1. Microgreens: Tiny Powerhouses of Nutrition
Microgreens are young, edible seedlings of various vegetables and herbs. These little greens burst with flavor, color, and nutrition, making them an excellent choice for indoor winter gardening. They are quick to grow, often ready for harvest within 1-3 weeks, and they thrive in small spaces and minimal light. Popular microgreens include kale, arugula, radish, and sunflower. Not only are they delicious additions to salads, sandwiches, and garnishes, but they also pack a concentrated punch of vitamins, minerals, and antioxidants.
I have taken sprout seed mixes and let them grow into microgreens with tasty results. I have used a ceramic microgreen tray with a coir base for the roots with success. I’ve also used a larger plastic tray lined with paper, but this one did dry out quicker. A note on the latter: the paper is placed on a perforated tray with a drainage tray beneath it. I haven’t tried the tray with soil yet, so I can’t discount it as a good system to use yet.
No matter which method you use, regular misting of the seeds and greens is required. I failed to do it one day and was left with some wilted and withered greens.
2. Spinach: Leafy Greens for Nutrient-Rich Harvests
Spinach is a cold-hardy vegetable that thrives in cooler temperatures, making it a perfect candidate for indoor winter gardening. With bright green leaves and a rich flavor, spinach provides a steady supply of essential nutrients like iron, calcium, and vitamins A and C. Choose compact varieties and place them near a south-facing window or under grow lights for optimal growth. Regular harvesting of outer leaves encourages continual growth, giving you a fresh supply throughout the winter months.
I tried to grow spinach in my large hydroponic unit with little success. It germinated relatively quickly but basically quit growing after its first few leaves emerged. That’s not to say it’s not suitable for hydroponics. I do believe the room my unit is in is much too warm for spinach. It may do better during the winter months when the room is much cooler.

3. Herbs: Fresh Flavors at Your Fingertips
A windowsill herb garden is a delightful addition to any indoor space during the winter. Herbs like basil, parsley, mint, thyme, and rosemary not only bring wonderful aromas but also add depth and flavor to your culinary creations. Most herbs are relatively easy to grow indoors, requiring moderate light and well-draining soil. Regular pruning ensures bushier growth, and you’ll have a steady supply of fresh herbs all season long.
Although some herbs do not do well in hydroponics, my mint is flourishing. I cut it back yesterday and am dehydrating the sprigs for use in tea this winter. I have been eating it fresh as well, pinching back the growing tips to encourage bushier growth.
My self-watering herb planter (pictured below) will also be brought indoors this fall, which will continue to provide me with parsley, lemon thyme, lavender, dill, and calendula (marigold) for flavour and garnishing.
4. Carrots: Compact and Colourful Delights
Believe it or not, you can grow carrots indoors during the winter months! Choose smaller varieties or “baby” carrots that are well-suited for container gardening. Select deep containers to accommodate their taproots and provide well-draining soil to prevent rot. Carrots require moderate light and consistent moisture to thrive. Witness the joy of pulling up these vibrant orange roots from your own indoor garden.
I have grown carrots in containers before, but have yet to try them as an indoor winter crop. My house has a lot of natural light so I hope it’s enough for the carrots. I do have LED lights I can utilize as well.
5. Scallions: A Never-ending Harvest
Scallions, also known as green onions or spring onions, are a versatile and productive choice for indoor gardening. They can be grown from both seeds and kitchen scraps (using the root ends). Place the cut ends in water initially, and once they develop roots, transplant them into pots. Scallions can thrive in various lighting conditions, making them an excellent option for less sunny spots. Regular trimming ensures you’ll have a continuous supply of mild onion flavor for soups, salads, and garnishes.
I love green onions and there’s nothing better than fresh-picked. As they don’t have a deep root system they’ll be ideal for a pot placed on the kitchen counter. Between them and the chives I should be set for green onion flavour all winter long.
Wrapping it up
Winter gardening doesn’t have to be limited to the outdoors (and in a climate that reaches minus 40 degrees, it’s not an option). By choosing the right vegetables, optimizing light conditions, and providing proper care, you can enjoy a thriving indoor garden throughout the cold months. Microgreens, spinach, herbs, carrots, and scallions are five fantastic choices that offer a range of flavors, colors, and nutritional benefits. So, roll up your sleeves, gather your gardening supplies, and embark on a winter gardening adventure that will not only satisfy your green thumb but also add fresh, homegrown goodness to your winter meals.
