I noticed how rapidly the weeds grow, even with very little water. Whenever my drip system turns on, the initial burst of pressure causes the hoses to spray a small stream of water about 3' long, for about a second. I frequently find tracks of weeds growing along this little path that got dribbled on.
And they're incredibly robust. I'll cut them off with the stirrup hoe, and they'll re-root themselves where they land.
Weeds are like the perfect plants.
And then it occurred to me--why don't we just eat the weeds?!?!?
