Just like humans need food to survive, trees require water to flourish and thrive. While watering may seem like a simple task, improper watering techniques can put trees (especially newly planted ones) at risk for disease or death. Too little or too much water can damage a developing root. Plants eventually wilt if the roots are waterlogged or dried.
No matter if you have a “green thumb” — follow these best and worst practices for watering plants to help you encourage growth and health.
DO:
- Water trees when they need it – Although watering plants every morning is a common practice, trees are more likely to benefit from infrequent deep watering (no more than twice a week). Fully grown trees have no problem dealing with infrequent watering. However, newly planted trees require regular and consistent watering until their root system becomes fully developed and established. See the table below:
- Check water moisture before watering – Using a trowel, dig a few inches of soil to check the moisture level. The soil should not be dry or drenched. If the tree requires watering, dampen soil with a steady stream of water for about 30 seconds.
- Water trees at a soil level – Directing water at the base of a plant helps deliver the hydration to its root system. Use a trickling hose to slowly and deeply soak the soil and promote healthy growth.
DON’T:
- Water Too Little or Too Frequently – You may be tempted to water a tree frequently during hot weather. However, shallow water has an unfavourable effect on root development. Instead, choose a less frequent watering routine that thoroughly drenches the soil and encourages roots to reach for residual water found deep in the soil.
- Use Broadcast Sprinklers – Broadcast sprinklers can soak the trunk and leaves of a young tree, increasing the risk of a fungal disease. On a hot or windy day, much of the the water distributed by the sprinkler can easily dissipate before reaching the plant. If you do not have other watering options, turn down the sprinkler to prevent water from splashing on the leaves. Roots require water, not the leaves.
BEST WATERING TOOLS
- Garden Hose – Turn on the hose at a slow trickle and place it on the ground near the tree trunk. After 30 minutes, move the hose a few feet from the original position (still near the trunk). For large trees, keep it moving (and watering) for an hour or two.
- Soaker Hose – This watering tool allows water to slowly ooze out from its hose. It is perfect for slow, deep watering. Turn the water on to allow beads of water slowly escape and place the hose on soil surrounding the tree. Leave for it for an hour or more, depending on the size of a tree (or shrub).
- Bucket – Use a bucket if your hose does not reach the tree. Slowly pour water on the soil around the tree trunk. Use at least 10 gallons when watering young trees.
