Just thinking out loud here. Why do things grow where they grow?
AI Overview
Bacterial-dominated soils (high Nitrogen, low pH) favor fast-growing crops, vegetables, and weeds, while fungal-dominated soils (high Carbon, higher pH) are essential for trees, shrubs, and woody perennials. Bacterial soils cycle nutrients quickly, whereas fungal soils provide long-term stability, water retention, and, according to a Review Considering fungal:bacterial dominance in soils, enhanced carbon sequestration.
I planted Bur Oak acorns years ago and as they grew moved some of them around our farm. Some took and some did not. Those planted near other tress seemed to mainly survive while those planted in grassland away from trees did not. Was it the fungus in the soil near the trees that allowed the transplanted oaks to take root and grow? The acorns were started behind our farm grove sandwiched in between a shelter belt. The survival rate of the acorns was very high except the fox squirrels found some of them !
To add further to the above. The transplanted oaks were mainly bare root with very little accompanying soil. If we could have moved them with more of a root ball along with some soil maybe those planted in the remote locations would have made it?
