How do you grow cauliflower in a greenhouse for perfect results year-round? Growing cauliflower in a greenhouse ensures consistent conditions—steady temperature, even moisture, and protection from extreme heat—leading to larger, sweeter, and more reliable harvests than outdoor crops. Start seeds indoors, stagger plantings to avoid a glut, and choose self-wrapping or colorful varieties like Veronica or Susanna for visual appeal and flavor. With drip irrigation, airflow, and soil amendments, your greenhouse can produce A+ cauliflower from spring through winter.

Seed:

Nature hates a gap. That’s why weeds fill in every nook and cranny available to them outdoors. Sprinkling desirable seeds outside as the snow thaws on the south side of your home or Greenhouse Garden this spring lets you copy nature’s best efforts. Inside your greenhouse, scatter seeds on top of pots or flats. A light dusting of soil and a sheet of glass laid flat over trays keeps the humidity high until the seeds grow.

What Are the Tips for Growing Greenhouse Tomatoes in the Heat?
To prevent heat stress and flower drop in greenhouse tomatoes, use 40-70% shade cloth to reduce temperature and light intensity, maintain good air circulation with fans and open screen doors, and regularly water soil and paths to cool the environment and increase humidity. Selecting heat-tolerant tomato varieties, like smaller-fruited types or proven heirlooms such as Juliet and Cherokee Purple, helps ensure fruit set during hot spells. Combining these strategies allows growers to maximize tomato yields and extend the harvest season even in extreme summer heat.
