lots of plants can be used for cordage. you might already be growing something.
stinging nettle works well, you would want to rett the fibers. you can lay long stocks on top of some
pallets and leave them there through fall and winter and then collect the fibers in the spring or summer. I saw a
video once about crowing cannabis for fiber and they where doing snow retting which left lovely white fiber. If I got snow where I live I would try snow retting stinging
nettle. any plant that after you pull off the outer bark has lots of long thin fibrous material can probably be retted. anotehr way to do retting is to leav the plants under
water for a season. I think that can be one of the smelliest methods. I have never done any retting. if you can find a book or web page with
native basket plants used for basket weaving you will probably find plants listed that grow wild where you are that will be suitable. I don't know if there is anything you can grow that would provide you with a rope or cord faster. maybe someone else will know a faster means to having your own rope. I am very curious what others will say. This is something I want to do myself.
