See What Good Is A Cottonwood Tree?
The more I read about Populus deltoides, the more I love it. It’s a really fast-growing tree and apparently it can deal with the muck in my yard I call soil. If one wants to sequester carbon from the air, why not plant a bunch? I can envisage an acreage just filled with these giants. One could easily be self-sufficient in firewood, lumber for beehives and fencing, mulch for the garden, have abundant shade, food and shelter for many birds, swings for the grand kids, etc. Just plant cuttings or seedlings, add water, and wait five years. Amazing.
