2. Fungal Diseases Like Boxwood Blight

Fungal infections can also cause boxwood branches to become soft.

When you see soft boxwood branches with black streaks or leaf drop, a fungus might be involved.
 
This disease spreads quickly, so catch it early if your boxwood branches are soft from infection.
 

3. Environmental Stress

Extreme conditions make boxwood branches soft as the plant struggles to adapt.
 
Hot sun, freezing temperatures, or drying winds can damage branch tissue.
