Hello everyone...I want to build a 5 foot Hugelbed like the one featured in the 2011 Permaculture magazine featuring Sepp Holzer. I've built other Hugelbeds but none approaching that height. I gave it a go a few days ago but can't get the soil to stick to the steep slopes...plus, it's not 5 feet, looks unstable..a virtual mess really..so...I need help. A step by step to building a steep 5 footer (it should look like a tipi). Many thanks.
