Every vegetable and herb worth growing at home to cut your grocery bill — what each one costs in the shops, what it costs to grow in a pot, and how long until you're eating it.
Everything here is grown in containers, organically, with no chemical pesticides — on a windowsill, a balcony, a doorstep or a patio. No garden required. The numbers are per crop, not averages: what it costs, how long it takes, how big a pot it needs.
The direction your window faces, the month it is now, and the size of the pot you actually own decide which of these is a good idea and which wastes six weeks. The free web version works that out for you.
