About River Birch
River Birch (Betula nigra) is a native deciduous tree of the eastern United States recognized for its exfoliating cinnamon-to-cream papery bark and diamond-shaped glossy leaves. The most heat-tolerant birch, it naturally thrives along streams and floodplains; in NE Florida landscapes it performs best in zone 9a and with heat-tolerant cultivars (e.g., Dura-Heat®) when planted in moist, acidic soil with reliable irrigation. Starting at $24.95.

Care essentials
Light
Plant River Birch in full sun to partial shade; full sun with consistent moisture produces the best growth. In NE Florida heat, afternoon partial shade helps reduce stress, especially in drier sites.
Water
River Birch requires consistently moist to wet soil — it naturally grows along floodplains and tolerates periodic flooding. Water deeply and regularly, especially during establishment and dry periods; do not allow soil to dry out.
Soil & Fertilizer
Requires acidic, moist soil (pH 5.0–6.5); chlorosis develops in alkaline soils. Amend with sulfur if needed. Fertilize in spring with an acid-forming slow-release fertilizer. Avoid heavy clay without drainage or extremely dry sandy sites.
