Diatomaceous Earth as a seed starting medium - Page 56

Greatgardens · April 14, 2019

I've tried DE with fairly fine particle size from an auto parts store. (Think sizing similar to coarse sand.) Does OK, but I have one issue with it. Keeping it damp, the particles seem to "weld" themselves to each other after awhile. I don't get any better results than with Burpee's (coir) seed starting mix that is topped with about a 1/4" of vermiculite. Has anyone else noticed the DE particles sticking to each other?

Has anyone started leeks in DE? If yes, what were your results?
Thanks, Steve
