You did not indicate if you are dealing with sandy soil or heavy soil, marshy, deep or ?? Also, do you want to coppice to make Hugelbeds or do you use wood to heat? Comfrey is an excellent plant that produces a lot of biomass, if you can keep it from the deer. If you have chicken, they too will love it, just don't let them have the run too long or they will destroy your comfrey. If it is allowed in your state, Industrial Hemp also makes a lot of biomass (as tall as big sunflowers, and you could chip it?) Otherwise, depending on the size of your trees, you may want to put a crop like pumpkins, that could also bring income in the fall, while your trees are growing. Wood chips are a good alternative if you don't add too much at one time, but that can be pricey too. Poplars and quaking aspens grow fast, and although you cannot exactly "coppice" them, in a few years they would be the size of your thigh and you could grow pleurotus mushrooms on them: When you look at what will grow, look also at what will sell. A nice crop of pumpkins, squash or even cukes would also solve your mulching problem if you plant them thick enough. Good luck to you. Frenchie
I am planning to use the coppice wood for heating eventually with a few trees left to grow nuts. We don't need as much grass as we have as we are not planning to keep many animals, just a few chickens. Therefore, a fair proportion of our land can be turned into woodland as this will produce a useful crop and give us an element of energy security in the future. Our soil is a deep loamy one, it has managed to retain moisture despite a very dry summer and is being helped by mature grass which has toppled over forming a natural mulch. I have finished this years experiment. About 200 trees have gone in with a good organic mulch around them, I will periodically check them to stamp down tall grass and/or re mulch with chip or straw and see how they get on next year and continue to plant with any necessary adaptations. I will experiment with the pumpkin idea, perhaps a few handfuls of compost in amongst the organic mulch and a few seeds on perhaps 15-20 of the trees as an experiment. I will also order some Comfrey root cuttings and see how they go as well. All in all, the trees have gone in well, they look happy and it took about 2 days of work to collect, plant and mulch, so fingers crossed for a good success rate!
Many thanks for all the suggestions
