Soil and mildew


(Paul) #1

I have a 5 gallon bucket of bonsai soil.
About 2 days ago I tried to use it but it had a mildew smell.
Is it useable or is there something that can be done to make it usable.

Just spread it out in the sun and let it dry out, then collect it. If you want to go the extra mile, snag some concentrated H2O2, dilute it 50:50 with water and give it a good rinse. I’m sure there’s other stuff you could do. Definitely don’t toss it.

Drying it out in the sun is a good idea. What are the soil ingredients?

  1. Napa #8822
  2. Pumice
  3. Lava
  4. Chicken grow grit
    All in = parts by volume
    If I have it I sprinkle a handful “Espoma Bio-Tone starter Plus”. it’s a mycorrhizae inoculate.

Hmm, no obvious candidates for the source of mildew. I wouldn’t hesitate to use the soil once it dried out, though I might not use it for my best trees.

If you dry it and use it and the smell comes back, I’d look into where it’s coming from.

Thank you everyone for your help. If anyone else has different ideas send them along.

BTW Tyrones I use a cap full of H2o2 on cut flowers in a vase of water. It gives me an extra week or 2 of nice flowers.
