You do have to be careful when you ask for gardening advice online. People can say anything they like, so you're going to come across different people with very, very different opinions.

Everyone sounds equally confident online

The internet has a way of making everyone sound equally confident. Someone passionately recommending you plant tomatoes in shade gets the same megaphone as someone with thirty years of dirt under their fingernails. You click through gardening threads and find absolute contradictions—sometimes on the same page. One person swears by organic methods, another insists synthetic fertilizer is the only way. Both write with total certainty.

This applies far beyond gardening. We're all navigating expert-sounding advice on health, money, relationships, and work. The real skill isn't collecting more opinions; it's developing a feel for which advice actually fits your specific situation. That neighbor who grows incredible roses probably knows something valuable, but their exact method might not work in your climate or with your schedule. The trick is taking what resonates, testing it small, and trusting your own experience as much as the confident voice on a forum.

The uncomfortable truth is that you become your own expert by trying things, failing quietly, and paying attention. No amount of scrolling replaces that.
