Whether you are craving fresh harvests during the winter or live in an area without gardening space, you can grow edibles in your own indoor garden.

Winter always seems to sneak up on me. It’s not until the first snowfall that I consider the growing season over. Up until then, I am still clipping hearty herbs and fall greens. Once the snow falls, I am reminded that soon the ground will be frozen, and the garden covered with a heavy winter blanket. I start to miss freshly harvested greens quickly. Most years, I have a good supply of fall greens such as lettuce, spinach, chard, kale, pak choi, and other leafy greens to fill the refrigerator before the hard freeze. Some years, I lose my fall greens to the hungry deer as they prepare for winter too. Since I can’t garden outside during winter, I began experimenting with growing food indoors. I started with herbs and then progressed to salad greens and more.

What Can You Grow in an Indoor Garden?

Over the years, I have tried growing edibles indoors in winter using these DIY Grow Light Shelves. It is amazing what you can grow with just a little effort. Harvesting fresh vegetables and herbs add lots of flavor to winter comfort foods. For the best results, choose plants that will grow under artificial light, mature quickly, and stay compact enough to grow in containers without outgrowing their space.

Beets

Growing beets indoors will provide you with delicious beet greens and delicate baby beets. Beetroots will need deep pots, at least 6-inches high. Harvest: Ready to harvest as baby beet greens in about 6-weeks.

Harvest young baby beets in about 30 days depending on the variety. Varieties to Consider: Detroit Dark Red BeetsGolden Boy BeetsChioggia Beets, or this Gourmet Beet Blend for variety.

Bok Choy and Pac Choi

Bok Choy or Pac Choi is a delicious addition to soups, stir-fries, and salads. Harvest: Ready to harvest whole in 4-weeks at the baby stage. They tend to bolt quickly, so go ahead and harvest them small and sow more seeds, or snip the outer leaves and let the plants continue growing. Varieties to Consider: Bok Choy Tatsoi Rosette, and Bok Choy Toy Choy.

Carrots

Short and round carrot varieties grow very well in 6-inch deep pots. Choose a deeper pot for longer varieties. Harvest: Baby carrots are ready to harvest in 6-8 weeks.
