Your thoughts?
if i can do it by hand i will. i don't use sprays.
do you get a lot of dirt/sand blown on the wind?
it may be hard to keep a rock garden in a place that
gets a lot of wind.
you can always try it and do controlled experiments
to see if it makes any difference.

Yes, a lot of wind and dust storms.
I have so many weeds that is beyond my control.
I have "amber waves" of cheat grass.
for that you'll need a way to trap the dust and wind
blown seeds and get them down into a shaded area where
they won't germinate. not that it would be 100% effective
but it would reduce the weed burden. one design for a
weed free pathway i have in mind means a lot of work and
probably has flaws i've not considered but to put down
a trench and then to line it with thick mil plastic or
even aluminum sheeting (if you have a lot of digging
critters like moles, chipmunks, etc. about) and then
build a pathway about half a foot above it using a metal
screen so that any dirt and weed seeds can fall through.
set it up so that it drains to a few spots that can be
cleaned out once a year or so. a good rinse with a hose
or a heavy rain should work. some seeds will still be
trapped in the rock mulch above the pathway but it will
reduce the problem. an entire rain and rock garden
could be set up and then if you filter the water to
remove any weed seeds and dirt then the water could be
used on a garden. etc. no, i've not done anything
like it here yet, but i have some areas that are pretty
weed free just because they have deep rinsed crushed
limestone mulch and the only weeds that grow in those
spots are the large seeded ones that were grown on a
nearby fence. morning glories... ugh... almost ten
years later we still have some sprouting and growing.
another approach would be to design the place to funnel
the wind and thus any dust and weed seeds to go into
certain areas and not places where they'll be able to
grow.
just ideas to kick around... be glad you don't have
tumble weeds.
