Preparing Your Garden for Late Frosts

To protect your plants from unexpected frosts, implement the following strategies:

  • Use Frost Cloths: Cover tender plants overnight with frost blankets or burlap to insulate them from cold air.
  • Mulch Heavily: Apply a thick layer of mulch around plants to retain soil warmth and moisture.
  • Choose Frost-Resistant Plants: Select varieties known for their cold tolerance, such as kale, broccoli, and lettuce.
  • Delay Sensitive Planting: Wait until the risk of frost has passed before planting sensitive crops outdoors.

March is an excellent time to plant a variety of vegetables and herbs in Zone 10. These plants can thrive despite the occasional late frost with proper protection.

  • Leafy Greens: Lettuce, spinach, Swiss chard
