Maybe make it every 3 weeks. My 2nd and 3rd double rows (of about 35 feet) are now ready, and we still haven't finished off the first row yet. Kind of figured I would give most from the 4-8th rows away to a homeless shelter, and even then 150lbs may be too much for that one particular shelter-if the plants can even survive the frost that historically could start happening any day now-even though we don't see any in the 15 day forecast. I didn't expect that the 2nd and 3rd row would ready at the same time (I don't remember planting them at the same time), and no way we can eat about 70lbs of green beans that quickly-so I guess we'll be trying to give those away too as we certainly don't have the freezer space.
Anyways, as I said towards the end, if you do this for survival you got to properly manage what you grow-especially if your resources are scarce. Otherwise you can run into situations with an overbundance at one point and nothing later.
