Q.Is All Your Advice Based On Being In The USA Please?
I have 3 acres of land in Puglia, mostly covered with olive groves, however I want to build a garden that compliments the groves, allows for a kitchen garden, reduces risks such as ticks, rodents and supports my intention of being as self sufficient and environmentally caring as possible. But all I can find is information for plants etc by zones which only apply to the USA. Really wanting advice and an area to share experiences not in the USA and hoped this would be the place, please advice
