Physan as preventative

[Lin]

Want to inlcude Physan on a regular basis to keep rot under control. What is the dosage of Physan per gallon of water? Would I just water them, or dunk?

Thanks so much for your help.

I have not found this practice to be necessary.

It is also in my experience and opinion not something that I'd advise doing as it may cause undue root damage to some of your plants.

I use it once a month regularly and it does help in my circumstances (and others I've talked too).

I have to look up what ratio it is, but I just spray it on. It has helped with the Phals and some of my older more delicate Catts.

Did you ever get a chance to look up the ratio?

I use one tablespoon of physan 20 per gallon. My plants are outdoors so I use a sprayer to soak my plants and the potting medium, once a month during the humid summer months. I don't use it during the winter. There's a new product physan 27, but I've never used it.

thanks so much!

the lable on my Physan 20 says 2 teaspoons per gallon...but as King mentioned it can cause root damage used too much ...especially if mixed strong ...I have one or two that dont like it at the 2 teaspoon per gallon so I do 1...I do use it once a month ...but usually spray twice on sucessive days when I do

I use it at the ratio: 2 tsp/1 gal. I've never done it twice successively. But I think I will go to 1/1 and twice. I like that. Thanks!
