Google is a great search engine, directs me to old threads here with good info all the time...but as you already know I came up empty on this subject.I wont lie I GOOGLED it!.....There was no definate answer but I would use at least a 1cup per bag.....or more?....ive used de before,only outside.I did not know there was so many uses.There is food grade and garden grade.From what I gatherd food grade has been washed/cleaned?,garden grade has not.I only knew De was sold at the feed store and was used for garden bugs and livestock for ticks and fleas.You can eat DE and is used for all sorts of stuff.Ive also learned about all the uses for Colloidal Silver.....anyway www.dirtdoctor.com
www.themorristribe.com
www.earthworkshealth.com are a couple sites with good info.
You're topdressing with it, while I'm mixing it right into the medium before I plant. Perhaps there isn't a correct measurement, so I guessed at 1/4 cup/gal.I just ran it around the top of the whole pot. I didn't know you were suppose to measure it,lol
Can you dust plants with it or only for use in soil. Thanksi use mabe a cup per 5 gal pot, im all organic

Im looking for a good organic insect repellant options.
I am re-thinking my quantities on DM, as in I need to use even more. I still have a few gnats, but they are adults and wingless...DM must have cut holes in their wings.I use it in my soil mix and just eyeball it. I don't measure, but probably use a couple pints for 20 gallons of soil. I don't know if it adds calcium to the soil, probably over time, but I use it as an anti-caking agent; that is what it is used for in the food industry.
As for using it in teas, I don't think it would add anything to the mix except viscosity.
Responded via other thread, pasting text below:Getting the DE wet I think would make it less effective. We use it as pool filter media. The way it works is when wet, the sharp glass-like edges lock together letting only the smallest particles pass through. If wetted all the sharp edges would be locked together and do a minuscule amount of cutting I would think.
