Permaculure zones – in a bag
Zoning is a Permaculture design technique where we put the elements or items of a design in areas according to need. The needs of the item and our use of it. For instance, we need tea herbs, so we plant them in pots on the kitchen window sill, (zone 0) some more near our doorstep (Zone 1) and other types of mint that love a lot of space, can serve other purposes such as suppressing weeds and only need occasional attention (such as mint) further away, perhaps in Zone 3.
Permaculture Techniques such as Zoning are scale-able. The design technique called Zoning can be applied on large farms, city apartments, urban homes, kitchen design, and even in the design or re-design of a little bag. (you can redesign a bag by inserting pockets, wallets or compartments. This is similar to how we re-design a property by using fencing for the zones).
