I have tackled plenty of 500 foot rows of things to hand weed, like carrot where there are four laps of them in the bed, but here on my new place, the end of the row comes like a surprise. I love the interaction, the intimacy, getting low down with the garden, the moments squatting and traveling along bright lacy green carrots full of ladybugs and other splendid things.
I do many different types of "weeding": tilling, cover cropping, hoeing - I till the paths with a walk behind and scuff with my foot. I want to make a little snap-on hoe for the front of my boot - that would be really handy. In the past, with many more acres to weed, I used several mechanical implements on the tractor.
But the most pleasant hours in the garden are when I am off the machine, slowed right down by a squat, and fully present with the life of the garden.
