Oidium or mildew in mint pot. Reuse soil?  RSS feed

I have oidium or mildew ( cannot see the difference from web pictures) on and off with treatments of water and baking soda. The plant seems healthy ( lots of folliage and blooming for months.) but is covered with this fungus (oidium or mildew).

To make short it is a Canadian mint ( Mentha arvensis subsp. borealis) and i don't really like it's taste so i won't keep it. Strange thing that it spread once on another mint variety and was treated with ease.

I planned to use this pot for another variety of mint i started growing from a stem actually in a smaller pot.

My question is: can i reuse that soil? Can i treat the soil kinda baked in the oven and refertilized by mixing with my garden soil or worm casting(not ready yet)? Should i clean the pot itself? If yes what with: boiling water? Vinegar? Baking soda? All of these method?

Thank you for your help.

Mint is tough stuff I owner if the issues drainage in the or lack of it . I would replace the soil with something better draining .
I was under the impression that odium is French for mildew

Mildew in french is mildiou (same prononciation and yes i'm french Canadian).

Found in Wikipedia that powdery mildew is one kind of oidium so at the end it is the same...

I don't think the draining is the issue since it is in pot and dry out quickly. All of my other plants did not had powdery mildew (except one contamination of the mint right next to it and was treated with ease).
This type of variery of mint even grow on lakes and river shores.

I highly recommend not using the soil from the infected plants.

hau Maxime,  

Mildew usually thrives in damp areas, I would look to the environment where the mint was growing.

You would need to sterilize the soil, the container, the container tray to keep those from being a source of contamination.

To sterilize soil you need to spread it thin on baking sheets if you are going to use heat as the sterilizing agent. It will need to be heated so the temperature of the soil is above 180 f, for 30 minutes, this will kill all organisms.

If the container is clay, you can use heat to sterilize it too.  If it isn't then you will need a chlorine bleach followed by a vinegar rinse then three or four fresh water rinses to remove both the chlorine and vinegar.
