Damping-off: Symptoms, Causes & Control

What it looks like

The stem pinches in at soil level, turning water-soaked to brown and thin, and the seedling topples over. Infection before emergence makes the stand uneven with missing plants.

Causal organisms: Achlya klebsiana, Cylindrocladium canadense, Fusarium avenaceum, Fusarium commune, Fusarium oxysporum, Fusarium proliferatum, Fusarium solani, Fusarium sp. and 36 more

What other growers did about it

A page like this one can tell you what damping-off is and what to try. What it cannot tell you is what actually happened to someone who had it on the same plant, at the same point in the season, and what they did next.

Gadenin is a free garden journal built around that. You photograph the plant, tag what you are seeing, and the entries line up by date for each plant you grow.

• Tag the problem and the app tells you how many other growers have logged the same thing on the same plant.
• Growers who make their records public can be followed, so you can read what they did and how it turned out.
• Next season your own entries come back at the same point in the year, so you check the plant before it starts.
