Do you think this will work?

Hi,
When we moved here 4 years ago I built a beautyful (about 20x10ft) rock garden outside the windows of my screen porch. There was quack grass in the small strip bed that was there which I removed. I used the lasagnia method to kill the shape that I wanted using mostly anuals the first year I weeded out any quack that came up. Well durring the 3rd year with now mostly perenials in place I started working on other projects and the whole bed became infested with the most huge hardy quack that I have ever seen. I guess it liked all the compost and other good amendment that I put on it. Sooo..this summer I removed all the rocks (think large pile on the walk that must be removed before winter), dug out the quack, which of course was deeper than it normally would have been (this took all summer) and replanted the plants. Here's the problem. I'm thinking that since there was quack in the grass that where I made the bed that was not visable it is probably in the surrounding lawn also. I want to put in a barrior. I got some of the 15" aluminum sheeting on the roll that you would use for roofing. I plan to install it using a streight edge shovel and rubber mallat before replacing the stones. I'm thinking I'll leave it up about an inch and then cover it with an old soaker hose slit down the side to cover the sharp edge. Does anyone have any other ideas how to do this? How about better ideas of how to install the rolled sheet or ideas of how to keep the hose from popping off the edge? Do you think this will be sufficent to keep the quack out?
Some of the rocks are quite large. I really don't want to have to move them again.
Thanks,
Catrina

The aluminum sheeting sounds dangerous and sharp. I don't know how you would keep a hose on it - glue gun? Caulk? Installing it won't really be simple either. Doesn't really sound that workable . . .

How about using roundup to kill the quack grass rather than removing all your stones?

There are a few threads on the garden design forum on edging. Perhaps the simplest is to just have a trench between grass and garden, and keep after the grass as it tries to cross that trench.

Go to garden design forum and search on edging, you will see a lot of advice and people who have experience.
