Watering Potted Trees: Reservoir vs. Top Watering

Is Bottom Watering via Reservoir Good for Potted Trees?

A gardener asks if watering an outdoor potted tree through its reservoir (saucer) is beneficial or harmful.

Expert Answer

Nick says reservoir watering is only for plants needing copious water (e.g., bananas). Most trees risk root rot. Better: remove reservoir, water from top until drainage flows, then wait until top 3 inches of soil are dry. Mulch the surface (keep away from trunk) to retain even moisture.
