Hi,

I soak seeds in 5% household bleach (1 part bleach and 19 parts water).

they are robust seeds (hard-coated or hard to germinate), or if they have

me fungus problems before, I use 10% household bleach. I stir several

and let the seeds stay in the solution for 10 minutes, stirring every

or two. I use this to clean up bulb scales and cuttings too.

One other approach for keeping seedlings fungus-free is Consan or Physan

generally use Consan Triple Action 20). I use 1 ounce per gallon of water

the seeds and soil surface to full wetness. These gentle fungicides are
biodegradable and have no lasting effect, so I mist the soil surface 2 or

a week while seeds are germinating if I have a bit of fungus problem or if

dealing with a seed type that has had fungus problems before. I find

to be safe with even the tiniest seedling. Consan is a quaternary

fungicide/bacteriocide, and essentially the same thing is used as a

disinfectant in hospitals (floors, bathrooms, etc.).

I also use Consan to wash down surfaces that have mildew and algae growing

them such as windows that get a lot of moisture, or lawn furniture, etc.
Although a fungicide its toxicity is quite low compared to something like

detergent or even caffeine. I do take care not to get it in eyes or stay

skin, it can irritate.
