There's so much info out there, all our brains would explode if we tried to learn everything!
I have a background in science, so the chemistry comes pretty easily to me. Start throwing around traditional methods (what's the phase of moon got to do with it?!?!), and my eyes glaze over. And even though I spend my day with the Latin names of bacteria, I can't begin to handle all the hybrids and cultivars that exist among garden plants. We all have our own strengths and weaknesses, so go with what works for you
