the guys took down an old hackberry on the campus the other day. it was decaying badly, had hollowed out and the hollow had filled with debris that eventually turned to soil – the tree was putting out roots from callus tissue inside the hollow – roots in the soil in the ground and inside itself both. kind of interesting.

The roots look like advantitious roots that were growing into itself, not just roots coming up from the soil. Interesting.

I was once in a huge silver maple when I realized that a limb, which was about 12" in diameter, was actually another tree growing out of a large pocket of decay!

I hade one where the water draining out of a huge cavity supported roots growing out of a fissure. it would take long enough to drain out that it looked like hydroponic drip irrigation.

I've seen rooting into "decay humus" at 40 -60 ft up.

seems to be mostly the riparian species that can do it though.

Yes seen in maples and willow oaks, but also in xeric red oaks too. I doubt there are any sp. that do not make adventitious roots if conditions are right.

Glad m-sama is still with the u and still enjoying the wonder of trees' adaptability
