Definitely, this place is a goldmine of information- little quieter in the last few years but it’s a quality forum and always has been imoI spent much of this season fighting aphids and fungus gnats; I hear ya.
The thought of sterilizing soil is worse than the cure IMHO
I now keep fresh nematodes handy (Steinernema feltiae) and Dr Zymes eliminator. Best practice is to keep my soil healthy but sometimes….you need an intervention.
I even use potato slices as opposed to sticky traps to monitor my soil for fungus gnats. I found that info on a local agricultural extension service web site. (works for me anyway)
Every time I check in here (almost) I find a new medium being used or a new twist on what I’m doing. It’s amazing the information freely available here.
