Watering New Red Oak: Ditch the PVC, Use Sprinkler Method

Why PVC Pipes Fail

Two 3″ pipes only wet two narrow columns. Roots need uniform moisture across the entire root ball.

Better Method

1. Pan test: sprinkler until 1″ in pan.
2. Water every 3 days for 1 month, then weekly until leaf drop.
3. Mulch 3″ (off trunk).
4. Next spring: weekly if no rain.
