How do you stop invasive weeds from next doors garden growing in mine?

I hope you and your neighbor are on talking terms. Some folks don't care what their neighbor's feel. . and then some are great., and try to keep their lawn in order of neatness. I am always pulling the weeds from our yard, because he doesn't care of his. Then, of course, the weeds will blow with the next storm, or birds can share too. This is a on-going project. Best wishes, J.

If they are encroaching in the ground into yours, trying digging a strip at your lot line and insert some 4" black plastic edging. It does help to stop weed creep. if the weed seeds are blowing in your yard from your neighbour's (like mine), then the only solution I know is to diligently weed your yard and use "weed and feed" products in spring and fall. Good luck!

That's not the neighbors fault. Spray weed eater all along the fence, that's the only thing you can do.,

If it's windy most of the time like it is here, you just have to keep a handle on it.

We have no fences in the front yards, So if I see dandelions poking up I walk over and pull up the flower so it can't bloom. Did this last year and we have only a few left Between our yard and their parking strip. Die weeds die! Also my husband mows their parking strip, makes for friendly neighbors.
