I would like to take some good suggestions/advices here because I
guess the garden people are all here.

I am not a garden person myself, I hate lawn care. I did some crazy
things, and probably ruined my backyard, (which is about 33'x33') --
took away all the grass, lay down filters, and pave the yard with 4"
G.A., and on top of the compacted G.A., I put 2" pebbles. I still
leave 3 8'x10'-sqared bare-earth areas, now I am planting some trees
and peony on them. And my house is very close to my neighbors, even
the smallest truck can not pass to the backyard, I did all the above
stuffs with a small cart. If I had known the drawbacks, I would not
have ever done so.

I did these last year, thought it could stop the weeds, but I started
seeing the weeds soon. Now it is the second year, and now more weeds
are poping up the pebbles. Currently I spray salt on the weeds, in
order to kill them.

What would be an easy way to prevent the weeds on the pebbles?

Also if I do not have to remove all the pebble and GA, what can I do
to improve the yard? I wish I could have some simple solution, say how
about put concrete on the yard? I know this is some kind of madness.
But any good ideas?

Thanks a millions.

Perhaps the most sane thing would be a torch attached to a grill sized
bottle of to flame the weed seedlings periodically.
Seeds will come in on the wind and in the birds and soil sterrilants
are less than eco friendly.
You could get yourself a nice sized scrap of black rubber roofing/
pond liner and move it over areas you want dead during the heat of the
day.

Forget a Japanese garden as they require meticulous care and
maintainance to not look foolish and that doesn't sound like it fits
your lifestyle .
