The list we have provided below are plants that can thrive under tough conditions and are ideal picks for winter greenhouses.

  • Broccoli
  • Spinach
  • Brussel sprouts
  • Beets
  • Cabbage
  • Carrots
  • Parsley
  • Oregano
  • Pansy
  • Chrysanthemum

If properly installed, your greenhouse should effectively capture and trap the warmth from the sun throughout the day to sustain the correct temperature all through the night. Though on nights when temperatures dip into the extreme lows, it is important to take extra measures to protect your plants. Things you can do to keep your plants warm include covering the actual plant with frost fleece while wrapping the pots in bubble wrap. These layers of protection should keep your plants warm from top to bottom to prevent them from freezing during the night. Then, unless there is an extreme blizzard or cold during the day, it is important to remove these covers so the plants do not overheat.

If wanting to add more full coverage to your entire greenhouse, there is the option of adding another layer of greenhouse plastic to the inside of your hoop house. This will help to insulate the space a little more than the existing plastic will. Please note that even if this extra layer is added, you might still need to cover your plants if the temperature does drop.

During the Springtime, temperatures can greatly fluctuate. Due to this, you might need to remove or add a layer to your greenhouse plants to keep them from overheating or freezing, depending on the weather.

Keep your vegetables, flowers, and herbs protected all year round, in all types of weather, by coving them with sturdy and reliable plastic. Choose one of the best options on the market at an affordable price by looking over our inventory today.
