What Vegetables Do Not Grow Well in a Greenhouse

Greenhouses provide a controlled environment for growing vegetables, but not all vegetables thrive in this setting. Vegetables that require cooler temperatures, full sun, or specific soil conditions may not grow well in a greenhouse.

Vegetables that do not grow well in a greenhouse include:

  • Root vegetables: Carrots, turnips, and beets need loose, well-drained soil to develop properly. The limited space and lack of soil depth in a greenhouse can hinder their growth.
  • Cool-weather crops: Broccoli, cauliflower, and spinach require cool temperatures for optimal growth. The warm, humid conditions of a greenhouse can promote disease and inhibit their development.
  • Sun-loving vegetables: Tomatoes, peppers, and cucumbers require full sun for at least 6 hours per day. A greenhouse may not provide sufficient sunlight, especially during the winter months.
  • Nitrogen-fixing vegetables: Beans, peas, and lentils form symbiotic relationships with nitrogen-fixing bacteria in the soil. The sterile environment of a greenhouse may lack these bacteria, limiting their growth potential.
  • Vegetables that require pollination: Squash, pumpkins, and melons rely on insects for pollination. The absence of pollinating insects in a greenhouse can hinder fruit production.
