The one thing I would like to add about the gnats. It's the larvae you need to be concerned about. The munch on roots that limit the plant's abilities to perform. You won't see the signs in the leaves like you would with leaf miners of thrips. I also avoid peat. when you start recycling your soil or perform no-till practices you might have some problems.Sorry, I should have added that I'm growing in organic soil (Equal parts peat/compost ((this batch is a 50/50 mix of EWC and Bu's Blend)) and pumice, with the usual added amendments), with barley mulch on top of that. I do also just throw the leaves that naturally fall off on top of my mulch layer, but I always do that and never seen gnats before. The only thing I can think of is maybe it has something to do with the Bu's Blend? First time I've used that in a soil mix and my plants are loving it. Like I said, the gnats don't seem to be affecting my plants, but they still bug me (no pun intended)(seriously, no pun intended haha).
Pull the plant gently out of the pot and scope the roots with a handheld microscope, sounds like it could be root aphids.
Hhmm...You just gave me an idea...DUCT TAPE!When you are growing using organic methods be very cautious about what you add to your environment. Advice about sprays and adding stuff to your soil can be very dangerous to your microbiology.
Does it work with coco coir too? I’m using mint but doesn’t seem to work.I’m a big advocate of diatomaceous earth. It gets rid of insects, is natural and non toxic, can be used to condition soil and helps plants absorb nutrients. I’ve been mixing it in with topsoil/perlite/vermiculite and my plants are loving it!
I was just going to suggest DE also. Not only will it clog and suffocate the insects breathing holes, it's also a good source of silica I believe. I'm on my first grow after 30+ years smoking. Growing in hydro but seeing 1 gnat got me nuts (killed it with my bare hands ☠, former MarineI’m a big advocate of diatomaceous earth.
