Regular trees work quite well and are cheaper. You just have to harvest them and not burn the wood, or turn it to biochar.

Actually burning the wood works just fine, provided you can sequester (see BECCS, along with recent developments in basalt based CCS).

There are not enough natural trees to do the job because we have taken most of the really productive land to grow food. While there is some potential to use biochar in some locations, it is not going to be enough to get the CO2 levels down at the pace we need.
