Several years ago we completed taking down five huge pine trees! We chipped what could be chipped and then I had a bunch of pine that was left! I had just started learning permaculture and decided that I would give it a shot...not sure what the tannin would do for the bed! I installed the first one in my front yard just inside the easement in fall, planted it with peas and oats to over winter and then that spring planted a blueberry at each end and 3 asparagus on each side! I am so thrilled with the results! I only "tasted" the first year...I immediately installed another one!
Picture 1- dug a trench and laid down logs. Picture 2- pyramid as high as it would stack, mixed with rabbit
compost, etc. Picture 3- spring planting of blueberry and asparagus before mulched!
