Watering Your Tree

Dry conditions are a major cause of tree stress and can lead to permanent damage, especially in young trees. Unlike grass, trees do not go dormant during times of drought; they continue to try to grow. Global climate change is projected to increase the intensity, duration and frequency of dry events; therefore, watering your trees is an important step to help them establish and live a long, healthy life!

Trees need water even in the fall to be healthy and strong going into winter, especially evergreens.

How to Water a Tree

Water your trees regularly, especially trees planted in the last two years.

Like all plants, trees need regular water. Newly planted trees that are trying to establish themselves and recover from the shock of being transplanted are especially susceptible to dry conditions.

Watering your trees slowly and deeply is best.

  1. One easy way to do this is to turn a hose on very low and leave it at the base of the tree for 30-60 minutes, or use a soaker hose coiled around the “drip line” of the tree.
  2. Another way is to drill 2-3 holes (3/16 inch holes or less) in the base of a 20 litre (5 gallon) bucket. Fill the bucket and walk away, allowing the water to drain slowly into the soil.

*It is important to water your trees during the growing season from May until September*

Cost to Water your Tree

  • Your trees need around 2.5 cm of water per week (5 gallon bucket): One bucket per week costs around 7 cents
  • You need to water your trees weekly during the growing season from May till September: This will cost you around $1.40
