Growing vegetables without the warm sun might seem challenging, but there are around ten leafy vegetables and root plants that thrive in cool weather. These cold-resistant vegetables offer the opportunity for winter gardening and can even withstand the cold to stay in the garden all winter. Here’s a guide to understanding which vegetables tolerate the cold and when to plant them:
Which Vegetables Don’t Need Sun?
The belief that nothing grows without the warmth of the sun is challenged by a variety of cold-resistant vegetables. Around ten leafy vegetables and root plants benefit from the coolness of winter. While winter gardening is considered risky, planting cold-hardy vegetables in the right season can lead to a bountiful harvest in spring. Some weather-resistant vegetables can even stay in the garden throughout the winter, becoming crisper in the cold.
Which Vegetable Grows Best in Cold Weather?
Several vegetables grow well in cold weather, and their exposure to prolonged cold transforms starches into sugar, making them sweeter. These vegetables can tolerate air temperatures below –2°C. Notable examples include onions, garlic, leeks, rutabaga, broccoli, kohlrabi, kale, cabbage, collard greens, Brussels sprouts, arugula, broad beans, radishes, winter peas, and turnips.
Which Vegetable to Plant in Winter?
The list of vegetables that don’t fear the cold is extensive. Planting garlic in autumn or February, for example, allows it to survive and yields a harvest in May. Other vegetables like beets, carrots, parsnips, lettuce, chard, garden peas (before flowering), Chinese cabbage, endive, cauliflower, parsley, and celery can withstand temperatures of –2 to 0°C. While a harsh winter may slow their growth, it doesn’t kill these hardy plants.
Specifics for Some Vegetables:
Spinach: Requires a soil temperature below 21°C for successful germination and around six weeks of fresh air with soil temperatures above 4°C to reach maturity.
Green Onions: Plant in fall for spring harvest; grows slowly over winter.
Leeks: Left outside in sand, they survive severe frosts and become crispy. Young plants tolerate light frost.
Broccoli: Grows most vigorously between 4 and 21°C, mature broccoli is resistant to subzero temperatures. Plant from May to November.
Each vegetable has its unique requirements and planting periods. Understanding these specifics will help you decide which vegetables to grow in cold weather and plan your garden accordingly. Happy gardening!
