When pulling out weeds in the vege patch, I want to think of more ways that I can put it to good use that might be even better than merely letting it break down above the ground on its own (assuming you are on a property where you are responsible for for the green matter disposal).
So far I can think of:
Eating them if they are edible (meaning you don't have to plant so many intended garden greens / buy as many seeds from elsewhere, with all the sustainability considerations that that entails) - many field weeds such as dandelion are edible (including even the root), the greens of which is actually extremely nutritious unbeknownst to most.
Contributing them to green manure compost to put back into the garden once microbes have broken the weed down into highly beneficial humus / organic matter.
But what might be other ways? The more ideas the better. I am sure there are many.
