A greenhouse can be a great way to grow vegetables during the winter months. The crops you choose to grow depend on your climate and what you like to eat. Here are some crops that can be harvested from a winter greenhouse:

• Leafy Greens: Cold hardy leafy green vegetables like kale, arugula, chard, collards, and some lettuces are perfect for winter growing.

• Root Vegetables: Root vegetables do very well in a winter greenhouse. Carrots, beets, radishes, and turnips are all built to survive freezing temperatures and are ideal for winter greenhouses.

• Alliums: Garlic, onions, leeks, and scallions do very well in winter greenhouses.

• Brassicas: Brussels sprouts, broccoli, cabbage, kohlrabi, turnips, cauliflower, and many Asian greens can also be grown in an unheated winter greenhouse.

In addition to these crops, some gardeners also propagate perennials for the following spring and continue to grow winter greens. If you live in an area where the winter nighttime temperatures drop below zero, you may need to install a heating system in your winter greenhouse. You can also use grow lights to keep your greenhouse warm and provide UV light to encourage plant growth even in the cold winter months.

To maximize growth, youll need to space your plants properly and continue to fertilize your winter greenhouse plants throughout the cold months. Good insulation is also important to retain heat in your greenhouse, especially when it starts to get really chilly. Horticultural bubble wrap can be used to protect your plants from UV rays and keep costs down.
