I'm thinking of rejuvenating an old rock garden. (Think of a
mini-Stonehenge: the boulders are now too heavy and too deeply sunk to move.
Which makes me wonder if anyone knows how much of those real Stonehenge
boulders (on average) are below ground now four(?) thousand years later )

Yes, Stonehenge has been studied in minute detail. There's something
about it in Mr Darwin's excellent book on earthworms.

An old hops vine has crept into the rock garden. Can I get rid of it without
disturbing the other well-established garden plants in there? I hate
poisons, but I'm thinking the only way to do this, is to paint some chemical
on the new hops shoots and hope it will do the job. Question is: what
poison? And is this my only option?
Also, do I have to wait until next spring, when there is an abundance of new
shoots to play with? .... Pinetree


If you want to use chemicals, glyphosate gel is probably best.

If you prefer to avoid them, cut the shoots off at ground level. They
will regrow: each time they come up, cut and cook like asparagus.
