FAQ
Frequently Asked Questions
It is a hyphenated compound noun: damping-off.
Informally, some gardeners say 'seedlings damped-off,' but in formal writing, it's best treated as a noun (e.g., 'seedlings succumbed to damping-off').
It is primarily caused by various soil-borne fungi and fungus-like organisms (like Pythium and Rhizoctonia) thriving in cool, wet, poorly drained conditions.
Use sterile potting mix, ensure excellent drainage and air circulation, avoid overwatering, and sometimes use a fungicide treatment for seeds.
