River Birch Leaf Drop: Water Stress Solution

Paper bark river birch planted last year yellowed and dropped leaves in mid-summer, greened up, then yellowed again heavily. Owner asks if more water is needed.

River Birch = High Water Demand

Native to riverbanks, they need consistently moist soil. Drought causes rapid yellowing and leaf drop.

Watering Protocol

• 1 inch of water every 3 days until rain returns.
• Then 1 inch weekly.
• Measure with pan under sprinkler.

Mulch Is Critical

Apply 3 inches of organic mulch 3 feet wide around trunk (not touching it). This conserves moisture and cools roots.

Consistent deep watering will restore health. River birches recover well from drought stress if caught early.
