I’m having a hard time understanding the weeding proscess, I understand that some weeds need different tools (ie a hoe, Werder, or herbicide) but I don’t understand exactly what weeds do and how to prevent them from growing (I originally thought to just weed them when their small and it’d prevent the large or partial weeds but it doesn’t seem to. Am I making a mistake or what?
