Physan 20 in terrestrial soil
 

Is Physan 20 safe to use as a soil drench in dirt? After going through the insert that comes with it, it mostly mentions sprays and soaks.

I'm having problems with mold and mildew under the bark mulch in several planters (even in full sun, go figure)- and if it becomes a problem with any planted Bletillas that I might have some day, I want to know if it's safe.


I just used a 1tsp:1gal on my roses (the moldy sunny planters) and I'm hoping they'll be okay- since I might have to use it on terrestrial orchids.
I might go back through later today and run regular water through the planters just to be safe....

No comments?

I lost my insert that came with the physan :(
I have used it in a potted plant that had a bunch of fungus growing in the soil - didn't hurt the plant at all.
I would think if it's safe for orchid media, it would be safe in soil - but hopefully others will chime in

Thanks Sonya- I was kind of thinking it might be okay, since it has directions to soak orchid 'compost'.

Yeah - I think so long as you follow the dilution guide it should be safe.
