The most common reason newly planted trees fail in the Treasure Valley isn't poor species selection or bad soil — it's inadequate watering during the first one to two summers after planting. The root system of a newly planted tree is a fraction of what it will eventually be, and it simply cannot pull enough moisture from the surrounding soil to sustain the canopy through a dry July and August without help.
The watering guidance we give every client after a planting or transplanting job is consistent: water deeply and infrequently, not shallowly and often. Surface watering encourages shallow root development and doesn't get moisture to the depth where it matters. A deep, slow water application two to three times per week during peak heat is far more effective than a short daily spray that barely penetrates the mulch layer.
Volume matters too. A newly planted tree needs roughly ten gallons of water per inch of trunk diameter per week. For a three-inch caliper tree, that's thirty gallons a week — more than most homeowners assume. A soaker hose laid around the perimeter of the root ball, or a slow-release tree bag, can make consistent deep watering much more manageable through a full Treasure Valley summer.
If you've planted trees this spring and are heading into the hottest stretch of summer, now is the time to confirm your watering routine is actually reaching the root zone. We're happy to answer questions about newly planted trees on your property.
Do you have any trees planted in the last year or two that you're trying to get established? How has the summer been treating them?
