Key takeaways

What to know before you act on this, from the SteadScape editors.

  • Install shade cloth by late spring to prevent bolting in salad greens, ideally by mid-May in USDA zones 5-7.
  • Use 30 percent shade cloth in northern regions and 50 percent in southern regions to optimize plant health during summer heat.
  • Construct support structures using 1/2-inch EMT conduit or steel T-posts, ensuring they are at least 12 inches deep for stability.
  • Suspend shade cloth at least 2 feet above plants to allow airflow and prevent heat buildup, especially in temperatures above 90°F.
  • Consider using white shade cloth in extreme heat (over 100°F) to reflect sunlight and maintain cooler conditions for plants.
