Check the soil. There is no way to look at the soil from above and tell how much moisture is in it. Dry soils can cause the death of small roots and reduce a tree’s capacity to absorb water, even after the soil is re-moistened. Drought stress can increase a tree’s susceptibility to certain diseases and insects. To check the soil’s moisture, use either a hand trowel, a soil probe, or place your finger into the soil Very dry soil will resist penetration and indicate the need for watering.
When filled with water and placed by or around a tree trunk, these vessels will allow water to drip directly into the soil around the roots. The bags let you deliver a set amount of water each time. They are a good way to keep your younger tree well watered.
There is no reason to water the leaves of a plant. Water the soil, where the roots are. The Arboretum recommends watering within the drip line of a tree, from the trunk out to the end of the branches, to reach the roots most effectively. The water-absorbing roots are within the top two feet of soil; you want to keep these roots moist but not wet. Avoid frequent, light watering. Instead, water deeply at wider intervals such as once a week. Let a garden hose run slowly at the drip line of the tree, moving it around occasionally. At medium pressure it will take about five minutes to produce 10 gallons of water.
If using a sprinkler system, place a straight-sided container under the sprinkler and water until it has filled one to two inches. If you deliver the equivalent of one to two inches of rain, the water will percolate into the soil about six inches, reaching the fine, water-absorbing roots.
Proper watering is the single most important maintenance factor in the care of transplanted trees. Too much or too little water can result in tree injury. More trees are killed by too much water than by too little.
Check new plants and trees often. Newly-planted trees, shrubs, and perennials are still establishing their root systems. Check the soil around their roots often to see if it has dried out. The tree draws most of its moisture from the root ball. The root ball can dry out in only a day or two, even while surrounding soil remains moist.
