March Gardening Tips

  • As soil can be worked, trees and shrubs can be planted.  

  • Fluctuations in temperature can result in damage to the flower buds of plants such as hydrangeas and magnolias.  

  • Easter lilies that are done blooming can be planted outdoors. Set the bulb 2-3" deeper than it grew in the pot. Mulch well if frost occurs.  

  • Starting in late April, once the threat of frost is gone, summer bulbs can begin to be planted out: caladiums, gladioli, and cannas.   

  • Apply crabgrass preventers before April 15th. Do not apply to areas that will be seeds or germination will be inhibited.  

  • Protect bees and other beneficial insects and don't spray insecticides on fruit trees that are blooming.  

  • Hold off on planting some warm-season crops like tomatoes, okra, and peppers, until mid-May.  

  • Mid to late April, after the threat of frost, sweet corn and beans can be directly sowed outside. Protect if needed from cold temperatures.
