Arborvitae Taproots: PVC Pipe Watering Is Unnecessary

Roots Find Water Naturally

Taproots grow downward seeking moisture. Installing PVC pipes to "direct" roots is a myth—it adds cost, compaction risk, and no benefit.

Proper Watering Method

1. Place pan under tree.
2. Run sprinkler until 1 inch collects.
3. Frequency: every 3 days for first month, then weekly through growing season (skip if rain ≥1″).

Why This Works

Deep, infrequent watering trains roots to follow moisture downward. Frequent shallow watering creates surface roots vulnerable to drought.

Mulch Matters More

3 inches organic mulch conserves the deep moisture you apply—far more effective than any pipe.
