Diatomaceous Earth: The Natural Killer
Diatomaceous Earth, also commonly referred to as “fossil shell flour”, are finely milled fossilized shells of minuscule organisms called Diatoms.
…..basically, it kills most “exo-skeletal” insects almost instantly. It’s like a flour. You dilute ½ tsp into a spray bottle. Try to find a bottle that allows you to twist the the nozzle to disperse up so that you can get under the leaves where the larvae and insects feed and hide.
Diatomaceous Earth is safe to use on your marijuana plants, and it works. Aphids, mites, whiteflies, etc. Use it a few days in a row as needed.
