Garden Guy Tips

  • Sunburn damage on plants occurs more in the winter than during the summer. To avoid sunburn damage, paint exposed parts of thin-skin tree trunks with a white latex paint. This is especially important for trees such as citrus, apple, pear, peach and plum.
  • Begin mulching to maintain the warmth in the soil for plants. Spread about 2-4 inches of mulch.
  • Keep pruners away from any plants that are frosted such as lantana, hibiscus, asparagus and bougainvillea.
  • Stay away from fertilization on frost-sensitive plants.
  • Start spraying plants with liquid seaweed to protect plants from further frost damage. Liquid seaweed has 3-4 degrees of frost protection in it.
  • Place PVC pipe with rebar in the bottom in an arch over plants. Then cover the piping with frost blankets.
  • When using a fertilizer on grass, convert to a product with nitrate-nitrogen in it.
