Pests & Diseases > Collar Rot

Seedlings are wilting, look weak at the base, are falling over or going rotten. Often white spider web thin white growth around the stem on soil surface is visible.


When the stems rot at the point of contact with the potting mix. This occurs when the tubes remain frequently wet on the surface overnight.


To avoid this you must water early in the day so the surface mix has a chance to dry out and the seedling stems remain dry. Once Collar rot is present it will most likely affect most or all of your seedlings.


No Cure. If seedlings are affected, separate them from healthy plants and destroy them – they will not survive. Ensure healthy seedlings are in a sunny, ventilated area.
