I had a spot on my asphalt driveway that was obviously being pushed up by a
root (there was a seam between two sections where water could get in so that
wasn't surprising). The last couple of days I tackled it, chopping up the
asphalt and digging around the root.
I expected to find the usual shape for roots, getting bigger as it got
closer to the tree. Instead I found something very strange. There was a big
lumpy bundle of twisted roots, up to 4 inches in diameter in places. But
they didn't go anywhere. They just wrapped around themselves and disappeared
into the soil in various directions. The really strange thing was that all
the branches were quite small - no more than one inch.
It's almost as if the bundle wasn't attached to a tree at all, but I assume
that one of those little side shoots must lead to a tree. There's a mature
ponderosa pine about 12 feet away so I assume that must be it.
I didn't know that roots could take such a bizarre shape, and also I'm
wondering how to prevent this thing happening again. I presume some small
deep root must have come to the surface some years ago and started that
whole process. I don't want to dig up more of my driveway than necessary to
get every tiny little root. I'm wondering if simply digging a deeper hole
and filling it with gravel before repaving would prevent root growth by
drying the zone out. (There's gravely soil there now).
Roots can do some strange things, as I have observed from many tree and shrub
autopsies in the past. As for the gravel- Roots will actually grow quite
easily through gravel due to the larger pore spaces, which allow for more
oxygen. We use gravel for healing in trees at the nursery, and the roots grow
through the gravel just fine.
There is a massive Norway Maple which straddles the property line between
the neighbor's house and my property. There is a communal driveway on a
steep slope, with a tall solid concrete retaining wall making a boundary
between the steep aspahalt-paved driveway to the east and my lower, level
driveway to the west. Halfway up that steep driveway the base of the norway
maple has been completely asphalted around as part of the upper driveway,
(I'm guessing at least 15-20 years ago), but it survives and thrives. At
the base off my side of the retaining wall, the soil is dense with maple
surface roots. So, apparently the roots have traveled straight down 8 feet
from the trunk of a tree, tunneled under whatever the foundation of the
concrete wall consists of, and then gone sideways for a considerable
distance. Even a person like myself, who has no great love of Norway maples,
has to have respect for the tenacity of a creature like that.....

How does the gravel heal a sick tree?
Or were you just heeling them?
Let's here if four homophones!
I would bet the term came from the same term used to describe the lean
a sailing vessal gets from the wind.
Apparently you have lived in a cave for most of your adult life... healing in
is a process of burying the rootballs of trees that have been balled and
burlapped, so the roots are protected from the elements. There are a number of
materials that can be used for this, mulch, dirt, sand, peatmoss, sawdust,
gravel, and so on. I was refering to the fact that roots grow through the
gravel quite easily due to the amount of oxygen in the pore spaces that the
gravel forms naturally.
Plants normally get carbon and energy from leaves. Were there any at all
I'd seal the pavement to prevent any further growth.
