How to Water Trees with a Deep-Root Irrigator

Trees need periodic deep watering to survive dry seasons. If not on drip irrigation, use a deep-root irrigator (~$30) to deliver water to roots. Attach to hose, insert stem 6–12 inches into soil beneath the drip line, turn water on gently for 5–10 minutes (depending on tree size). Repeat at 3 spots for young trees, 5–7 for large mature trees.
