Now if you actually want to have a survival garden in the woods it must blend in with the landscape, no matter where you are at it must blend in so it will not be stolen. Some things to do is cover the soil with leaves or some type of cover to make them blend in. Now you have to remember exactly where they are at or you may walk right over them yourself. Also don't leave any trails to your garden and come in from a different direction every time you go there so you don't leave a trail.
You still want to plant this garden in a remote place where no one will find it. But you also want your garden to be close to where you are. So you can keep an eye on it, and keep it properly watered and also watch the health of your plants. Now make sure your garden gets plenty of sun, this is important for the growth and development of your garden.Make sure you plant this garden in a place where it drains well like on the side of a hill. If you plant it in a low lying area it may trap water and drown your plants. Or be washed away by running water that flows down hill. Just be careful where you plant.
These are just a few things to consider if you ever have to plant in the wild, But be sure to have seed handy even if you have to buy it from a seed company at least you will have seed to survive.
