Hi, I live in the north of Sweden right at the arctic circle. I'm planning to set up some permaculture at my moms garden this summer. I'm especially interested in hugelkultur as we have lots of wood for this.
Our average annual temperature is around -5 degrees Celsius. Sounds cold, but in the summer the climate is great for growing, and my mom has been growing large amounts w/o permaculture for ~25 years.
I have a few questions:
Will hogelkultur work great in this cold climate?
I read somewhere that the wood breaks down in winter time, my guess is that this wont happen as much in this cold climate? Maybe I'll have to use solar heating and some pipes trough the beds to get it warm early in the spring, anyone tried something similar?
What size of the beds is recommended for colder climate? I'm thinking BIG, maybe close to 2m high?
And my final but most essential question; My speculation is that the colder climate will make the wood decompose at a slower rate. If this is true, would it be a good idea to put some manure in the beds as well? This manure will probably serve as a boost for the plants the first few years, but how will it effect the decomposing of the wood? Will it serve as a catalyst and have a long term positive effect?? My plan would be to put the manure together with the wood as the hugelkulture core.
I'll wait with great anticipation for all your experienced minds to work your magic!
Thanks! -Ivan
