Hello everyone, I appologise if this has been discussed already a bunch. I'm new and not to good at searching the forums yet...forgive me please:) However I am really excited to participate here as I love cacti and well any enthnobotony.
My main question is, does anyone know of a safe pesticide thats ok to use on cacti that will not damage the skin in any way?
so far I personally havent heard of any good ones, I want to make a tea/spray with the N. Rustica(tobacco), as I know that works great on alot of things but not sure for the cacti, I have been noticing alot of really little red looking insects on my cacti..it's really bothering me.
I have alot of black spots that are forming on my Trichocereus bridgesii, could this be from the bugs/insects?
any ideas on how to treat these black spots?
Thanks in advance everyone/anyone, real good community you got here...Peace:)
