Don’t grow weed in your garden unless you are certain it is legal to do so.

It is a manual process, but I’ve become reasonably good at identifying them when they’re just saplings. 5 mins a day of just me pulling on stuff keeps the yard mostly weed free. I do let some “weeds” stay that are pollinator friendly.

Also what has helped are native grasses and pollinator friendly ground covers like thyme that usually reduce the ability of weeds to take over.
