overwatering root rot and Boston Fern
Quick answer
If overwatering root rot is what's going on with your Boston Fern, the most likely cause is: Root oxygen deprivation from waterlogged soil — when pore spaces fill with water, gas exchange ceases, creating anaerobic conditions that favor Pythium and Phytophthora root rot pathogens in indoor fern containers without proper drainage
Start here:
- 1. 1. Test soil moisture with fingertip before watering — only water when surface feels dry
- 2. 2. Ensure each pot has a drainage hole and empty saucer 30 minutes after watering
