During winter nights, greenhouses can become cold and your plants are at risk of frostbite. However, if you keep temperatures in the greenhouse relatively stable and plant the right vegetation, you can have a thriving greenhouse throughout the winter months. Hardy veggies like cabbage and leafy greens such as spinach fare well in the winter greenhouse. If you’d like to grow herbs, consider perennial ones like parsley and fennel. Flowers like calendulas and pansies will bloom even in winter.
Key Takeaways:
- There are plenty of growing options in an unheated greenhouse, such as spinach and broccoli.
- Perennial herbs like parsley and chives handle the cold well.
- For flower options, try cold-resistant options like pansies or chrysanthemums.
