Why do you need good OPSEC in the garden? Well, when SHTF, rest assured hungry and unprepared neighbors will look upon your preps with great desire. And that includes your garden.
For those new to the world of prepping, OPSEC means Operational Security. The term is military in origin and means, in the vernacular, to keep your preps secret. The Organic Prepper has many articles stressing the importance of good OPSEC.
So how can we maintain good OPSEC in the garden?
Fences are one obvious method. Fences make it a bit more difficult for nimble (thieving) feet as well. But there are more subtle ways to hide a garden, most notably the idea of edible landscaping.
One note for clarity: I am NOT advocating tearing up functional garden space in favor of edible landscaping. I AM suggesting a way to turn otherwise unproductive spaces, such as front and street-facing side yards, into productive food areas. This method can also work for apartment and condo dwellers, who may be dealing with property management/condo associations who want to see flowers growing, not food.
There are also many edible plants growing in city yards that most people have no idea are edible. Some are very decorative. Be aware, however, that some are considered noxious weeds. Your municipality may fine you for growing them. As always, I suggest some research into your municipalities' regulations.
Identifying edible plants to use as landscaping
A plant identification app in addition to books on local plants might also be helpful. My favorites are Picture This ( app ) and a book called Midwest Foraging. I would suggest obtaining a book on foraging in your specific area.
