I’m a firm believer in not drawing a line like that. You’re not a bad person if you wanna use some miracle grow or pesticide spray. Just know what you’re using and research the chemical a little. But… I’m curious, what issues are you facing that makes you want to use some instant cure? I haven’t really come across an issue that requires something so powerful (and I’ve had swarms of issues with a new garden lol). There are some pretty gnarly products out there that are certified “organic” that will absolutely work instantly. Is there something in particular going on currently, or just asking in general?
P.S. I can definitely attest to the planting loads of different (native) flowers all over your garden. It does take a season or two for the array of bugs to gather, but it’s pretty amazing how well it balances out once established. It’s also a super easy (and beautiful) fix/investment for your yard. Just Google “(your state) native plants”, and take that list to Home Depot
