Watering Recommendations

Hillside Landscape, Inc.

How much water is enough?
Water stress is the result of both too little and too much water and one of the major causes of poor plant growth and death.

Over watering can be just as damaging as too little watering, especially to evergreens and perennials. Too much water will lead to root rot and drowning.

A two to three inch layer of mulch helps reduce water stress problems as it helps retain soil moisture and reduces competition from grass and weeds.

Most mature trees and shrubs should receive 1 to 1˝ inches of water per week. This is about the same as a mature lawn’s requirements.

Watering during the heat of the day or in the sun can actually burn the plant's leaves. It is best to water in the early morning or late afternoon; night watering is not recommended.

Each site’s water spigots or sprinklers are different. Grade and ground conditions can affect watering times. Recommended times are approximate and should be adjusted to your sites needs. Plant beds should drain away from the house.

Heavy clay soils predominate in our area will hold water like a bowl, drowning plants. Dig a test hole 12 inches deep and fill with water. The water should drain out in 15 -20 minutes. If it does not, you have poor drainage and you must adjust your watering schedule and resolve the drainage issues.
Follow these three rules when watering:
  1. Whenever you water, water deeply, not frequently and shallowly.
  2. Water slowly so that the ground can absorb the water.
  3. Put the water on the ground, not in the air or on the plant leaves.
Average Weekly Watering Times for new plants:
Trees: 4-5 gallons twice per week applied at a slow trickle.
(Tree gator water bags work well for new trees.)

Shrubs: 2-3 gallons twice per week applied at a slow trickle.

Perennials: Perennial and annual flower gardens should be watered daily until the ground is moist. Watering in the morning is best, although late afternoon/early evening is okay. Night time watering is not recommended.
Watering Frequency for New Sod:
(Do not water in direct hot sun-light)
  • Week 1: Water heavy, ˝-inch or more every day (In hot weather, water ˝-inch twice daily)
  • Weeks 2 & 3: Water heavy, ˝-inch or more every other day
  • Weeks 4 thru 6: Water heavy, ˝-inch or more every third day
  • Week 7 forward: Twice a week for the remainder of the growing season
Watering Frequency for a Mature lawn:
(Do not water in direct hot sun-light)

Water twice a week heavy, ˝-inch or more is better than frequent and shallow watering.

In extreme drought conditions, water three times per week.

Lawns need to dry out between watering cycles. Frequent watering does not allow the thatch layer to dry out and promotes mold and fungus diseases.
Give all plants a deep watering just prior to the ground freezing (around Thanksgiving) regardless of their age.

Consider a fall application of an anti-transpirant to any new or susceptible evergreens. Evergreens drawn water all year long. In the winter, new evergreens may not be able to drawn enough water to sustain themselves and dry out. This particularly true where evergreens are exposed to drying winds. Your tree care provider can apply the anti-transpirant. Try Autumn Tree Care at 847-729-1963 or visit their website at www.AutumnTree.com
