I did this many times as a youth, very poor return. First thing I see wrong is SWAMP, plenty of damn rich soil you where thinkin, me too. Survey says! Root Rot is the number 1 answer! slugs and snails is #2. You have to take care of em when they are little put a cut off plastic bottle or jug over them. plant on the very fringes of the wetland on a hill or rise dryer than where mint would grow, where the wild black berry vines grow.... Now there are deer and even coyotes that want to chew on your tender young plants you have to put a wire mesh around them, but damnit the slugs are still chewing up the tender leaves! loosely wrap several twists maybe 5 or 7 of bare copper wire 10awg spiraled around the stock. check it every so often and loosen the winding as needed as the plant grows. the wire carries enough current to deter a slug from climbing it. They touch it and recoil in horror, it's kinda funny to watch.
Oh yes and now we've made it through the hot summer and the cool fall days bring the swamps cool mist to rest upon your large thick colas. but what is this?
brown nasty fuzz? coming from inside my tasty nugs? oh no! the mold has been growing undetected for days thriving in the moist environment just inside the
suface turning those beautiful nugs into icky grey goo! perhaps the dryer soil beneath the alder trees would sheild them from the perpetual mist? If the plant filled the space wear a sapling once was, noone might ever notice the difference... and what is this on the roots of the alder? Nitrogen fixing nodules? how interesting...
A few well placed and well cared for plants will yield much better results. The larger they are when you put them out (within reasonable transport size) the better they will do on they're own. Once you have mastered this, then grasshopper you may turn a hillside into your own special garden.
