Lol! I don't keep up with it. I figured with 40 rows, even if I could do one a day it would take me over a month to go through the entire garden and in one month's time, that is the kind of weeds I am dealing with. I was using a heavy mulch of chopped straw but I ran out so all the most recent rows have no mulch. If I can mulch it helps tremendously, not only with the weeds but also the watering.
And of course I don't get to be in the garden evey day so you just have to prioritize and look the other way sometimes! i have seedlings I cannot find for the tall grass! right now I'm just trying to keep the money maker crops weeded...
