Keep Shade Cloth Ready for Autumn Heat

Many new gardeners believe that autumn weather is entirely safe for plants, but late-season heatwaves can still severely scorch your garden.

Keep Shade Cloth Ready for Autumn Heat

  1. Keep your summer shade cloths easily accessible instead of packing them away for winter.
  2. Monitor your local weather forecast daily for unexpected hot days.
  3. Identify tender young seedlings or cool-season leafy greens that are sensitive to intense sun.
  4. Drape shade cloth over these vulnerable plants when temperatures spike.
  5. Secure the cloth with stakes or clips so it stays in place during autumn breezes.
