Dogwood Water Requirements: Balancing Moisture and Drainage

Flowering dogwood (Cornus florida) prefers consistently moist, well-drained, acidic soil—not "a lot of water" in the sense of saturation. The distinction is critical.

Site Assessment

Before planting in your yard's center, evaluate:

• Drainage: Dig a 12-inch hole, fill with water. If it doesn't drain in 1–2 hours, the site is too wet.
• Irrigation: Lawn sprinklers often overwater trees. Dogwoods need deep, infrequent watering, not daily shallow cycles.
• Soil texture: Clay holds water; amend with compost or plant on a slight berm.

Planting Protocol

1. Plant crown 2 inches above grade to encourage drainage.
2. Backfill with native soil (no amendment in hole).
3. Mulch 2–3 inches, keeping it 6 inches from trunk.
4. Water deeply at planting and weekly (1 inch) during first two growing seasons.

Ongoing Care

Established dogwoods tolerate brief drought but suffer in waterlogged soil (root rot, Phytophthora). Monitor leaf scorch (underwatering) vs. yellowing/wilting despite wet soil (overwatering).
