Watering Asparagus Plants

General Guidelines

  • During the first 2 years after planting, asparagus plants need 1 to 2 inches per week. If you are not receiving adequate rainfall you will need to water. Use drip irrigation if possible.
  • Mulch around the plant with compost or grass clippings to help soil moisture and reduce weed growth.
  • After year 4 you can reduce irrigation to every 2-3 weeks.
