Plants are popping up in my rock garden and I want them gone, Help?

I had it laid 2 years ago and until now there have been a dandilion here a clump of grass there at most. This spring I got all sorts of green stuff coming up especially under the over hang of my neighbor's tree. There is a smal flower bed right near the house but the rest should be nice yellow pebbles and 6 flagstone squares. You can barely see two of the flagstons now for the weeds and grass. I usually pull up what ever stray green pops up but this year I can't come close to keeping up with it. What can I use to kill this stuff without haveing to take up all the stones and the garden sheeting beneath it? there used to be a lawn beneath and I do not care if it is all killed, except for my flowers . What can I use to kill off the greenery. Im on a fixed income so something do it yourself works best.

at little cost, you can just dump very salty water on the plants.
Reply:I use ortho "season long weed killer", works great!
Reply:I would take the time to pull it all up and do the sheeting beneath (pain I know) that is the only way you wont battle it every year.
Reply:Go to Menards and get some "Vegitation Killer".


This is exactly what it sounds like.


It kills everything!
Reply:Regular maintenance that includes weeding.
Reply:Round UP
Reply:Round-Up


It will kill everything though.
Reply:spray with round-up. 1 cup of bleach to a gallon of water works some times too.
Reply:Pull as much as will easily pull spray the rest with Round Up then sprinkle on Preen. It will keep seeds from germinating, it lasts for 3 months repeat if you have a long growing season or every spring. Anything growing from creeping roots will need to be pulled or sprayed as necessary.

Reply:Well, diesel or gasoline is what my grandfather always used to kill grass along his fense....once it kills it ....the smell goes away....
Reply:You should take some black garbage bags and cut to lay them out underneath the rocks. With no sunlight and it being dark it will get hot underneath killing weeds and other plants even before they began to grow. You might want to spray some weed killer before laying the rocks on. Ask a neighbor to lend you some ;)
Reply:There is a product called Roundup. It does an excellent job and will not hurt surrounding plants if the chemical were to runoff the sprayed area.
