Plants in the ground — especially newly planted trees, shrubs and perennials — need the equivalent of one inch of precipitation per month. If we have a dry period that lasts longer than two to three weeks, you’ll need to water according to these guidelines – when the ground is not frozen:

  •  Water during the day when temperatures are at least 50 degrees F to allow water to percolate through the soil.
  • Finish watering before 3:00 PM so water can drain away from the surface before sunset.
  • Water the soil around the plants, avoiding the trunk and crown of the plants. You can use an oscillating hose sprinkler for larger areas or open-end hose with water turned on low for smaller areas. Water beneath entire canopy starting 1/3 away from the trunk out to drip line of canopy.
  • A typical medium sized shrub may require twelve gallons of water and a large tree up to forty- five gallons per watering.
  • For potted plants, assuming they are in a quality frost-resistant black clay pot and have well drained potting soil, water approximately every two weeks.
  • Be sure to thoroughly drain your hoses and store them inside your garage or shed so they will be easy to access and use.
  • We recommend using Bonide Wilt Stop, burlap, and G&B Organics Soil Building Conditioner to help protect your plants through our cold, dry winter. All of these products are available at Moana Nursery

Remember not to water when the ground is frozen.
