The peculiar thing is, it has only happened to a couple of stems. The
rest are fine.

M experience is that slugs return to the same leaf night after night,
so that they will completely denude one plant before moving on to the
next. The exception is something like a runner bean, where they find
the stem more amenable to attack than the bristly leaves - once they've
chewed through the stem and felled the plant, they move on to the next
plant rather than continuing to eat the fallen stem.


Ah. That explains it. It is very strange that a few stray potato
plants have appeared in the earth next to my pots of potatoes and they
are totally unscathed.
