Removing the foil wrap is easy. Unlike some other methods the roots do not get tangled up or grow over and through the bindings.
Here’s the first after unwrapping.
And some more.
Now I can assess the shape better. Look at shape of the rock, flow of the trunk, flow of roots, etc to determine which side looks better. That can determine where the longer shoots will be chopped. These still have some growing to do so they may still change appearance. At this stage I’m just making some guesses and anticipating what may happen in the next few years and trying to direct future growth along the lines that I think will look best.
After preliminary pruning the tops.
Look at the mass of roots. Many of those finer white roots have grown since I wrapped it last winter. Provided moisture levels are adequate conditions between the rock and foil are ideal for root growth.
Roots do not actually need soil to grow. Humid conditions is all they need and that’s what foil wrapped rocks provide in abundance. Some of these did not even have roots sticking out the bottom of the foil last year but have since grown down and out into the soil.
From experience I know it is important to assess and manage the roots now. Too many roots may seem a good problem to have but over time they will all thicken and spread to completely hide the rock. No point having a root over Rock planting if nobody can see there’s a rock!
Also need to deal with crossing roots. As well as being confusing to the viewer, a root growing under another will push the overlying root out away from the rock as it thickens and spoil the arrangement.
After cleaning many of the new, smaller roots and removing some that cross over or under. This should allow the rock to show through the spaces even as the remaining roots thicken and spread.

and after cleaning the roots on that side.
Here’s another case of crossing roots.
A closer look at the root marked with blue….
Shows that it comes from the other side of the tree, ender the base of the trunk, under another important root then down the front of the rock.
That’s one root I will definitely remove now, before it gets the chance to start lifting the entire tree away from the rock.
A few of these little ROR starters are already good enough to pot up and begin training trunk and branches. Others still need some more grow time so those are rewrapped with fresh foil and will go back into pots or boxes so the roots and trunks thicken a little more next summer.
