Diatomaceous Earth
eurorackstarted grow question 2 years ago
Is it OK to mix in diatomaceous earth to my soil mix? It seems to have just about sorted the few Fungus Gnats that I had. Using a Half litre Pot I made a mix of:
4 Parts Shop bought compost
1 Part Vermiculite
1 Part Pearlite
2 Heaped Tablespoons of diatomaceous earth

Diatomaceous earth needs to be dry in order to work on bugs... so I would say this is not your solution! If you have fungus gnats (and who hasn't?!), get yourself some Mosquito Bits and use it... the package will tell you how to do that but I soak 4 tablespoons of the granules in a gallon of water that I'm going to use for 30 minutes (I put the granules in a strainer to soak as it's easier to remove them) and then, after adjusting the PH if necessary, use it to water your plants (or add nutes if you're going to feed). Takes care of the problem almost immediately.... if you have a really REALLY bad infestation, they recommend using it once a week for 3 weeks.
Fungus gnats live in damp soil so it says to me you're probably overwatering.... make sure the soil is super dry between waterings/feedings...
Good luck!

Plants do absorb diatomaceous earth from their roots and give new leaves with more silica content, therefore more pest resistant. I also read that it can help with fungus on soil. I always use on mine and they do fine outdoors (no pests). For large infestations of mites on my tomatoes I'd apply on the leaves and on soil, and it'd work.

some people mix it into their soil for a silica boost for anti pest properties it has to be dry powder afaik but not 100% on that. i stopped using it since i started doing my ewc loaded with hypoaspis miles and dont want to hurt them. they’re the true gnat killers :)

Just being cautious. I had a friend visit today. Long story short, before visiting me she went to a nursery notorious for spider mites. I did not know thisHow much should I be worried? She did not touch any plants directly. I cannot be certain that she had any mites on her. I am just being cautious. What is the best course of action? If my current flowering plants get mites, can I wash the mites off and still use the flowers2 years ago
