Self suffiency, can it actually be done? Well in a sense yes....to a degree!
Myself and my partner have grown veggies successfully for the last few years, either in pots or small raised beds. We also shared an allotment last yr with a friend (not recommended if both you and the friend are strong willed!)
We care for 8 lovely hens and one very singful cockeral, who give us enough fresh eggs to feed my family of four and half my friends!
This year we have moved to a new house with massive front & back cleared gardens - a complete blank canvas! Awesome!
Now both of us are no way the expert gardener/grower etc, we use the method - trial and error! I don't have the time to be faffing about too much about things, I don't care if my veggies are beautiful, I just care that they are edible, fresh and practically free!
Now we just need to get started........
