After pruning my trees I piled up branches and I was thinking of shredding these with some wood shredder and using them as mulch. But unfortunately there is no shredder nearby this village and I can't do it. My options are:
With a branch pile you can do many things including:
- leave them to provide cover for animals
- grow mushrooms in them letting them grow good there
- burn them
- make biochar with them
- dig a pit to provide a cool spot for water to come up through Based upon where you're at I highly suggest doing this: https://www.youtube.com/watch?v=2xcZS7arcgk
They will decompose in a few years. I have such a pile behind the house. It gets built up to about 5 feet each year, and drops to about 3 a year later. This is in a fairly dry climate with below freezing temperatures for 6 months of the year. In warmer, wetter climates decomposition will be faster. In colder or drier climates decomposition will be slower.
You can speed it up by adding finer cut material (lawn clippings, weeds) that help retain moisture. The bigger branches take a long time.
