To me, this is the one downside of ATP that I've discovered. So many members have been gardening for so long and so expertly that their memories of starting out are decades old.
I haven't noticed you doing this, but I do have advice for any expert giving advice to any beginner.
Any time you start a sentence with "Just ...", just delete that sentence and replace it with several paragraphs that explain everything that you've known and taken for granted for years or decades.
But, of course, that's incredibly hard for the expert! Those things are like breathing to the expert, but a mystery to the beginner. That's why experienced people say "I've forgotten more about XYZ than ..."
That's why my college used to pick out a few students who almost failed some hard course, but managed to figure it out by the final exam. The college hired THEM as teaching assistants because THEY knew what parts were hard to understand AND how to explain to someone who did not already understand. That's hard! It's easy for an expert to explain the complicated details that he or she still wrestles with, but explaining the basics is as hard as a fish explaining how to swim.
