Oak Trees Under Vinyl Deck: Watering Strategy for Covered Roots

Twin oaks (39" and 50" circumference) with vinyl deck (no board gaps) built over half root system. South Jersey, zone 6. How to water covered roots?

Challenge

Solid deck = no water penetration to covered roots.

Strategy

• Water exposed root zone normally.
• Supplement under deck at least every other week during growing season.
• Method: 1 inch via pan/sprinkler (difficult but necessary).
• Trees will adapt, drawing more from exposed roots.

Without seeing setup, this adaptive approach should work.
