We have an area near a rain spout that seems to grow every kind of weed that we do not want. Even though I consider weeds wildflowers, this area is right by the pedestrian door of the garage and near a bed of low-growing sedum which I do not want “buried” amidst the weeds.
We preferred not to have anything growing in this area but the rain spout seems to dump every seed there that has blown into the gutters and with the moist ground, they take root quickly.
The solution we chose was to use salt in this small patch of ground. It worked. There hasn't been anything growing there for two years, but this year a few things are taking root, so I will again spread some salt in that small patch.
Since my last application lasted two years, it's sure a simple approach to keeping an area clear. I do mean clear. The salt doesn't allow anything to grow so don't use it if it will wash into an area you want to grow things.
This is a great way to keep weeds from growing between pavers and stones. I imagine it would also kill moss which is a common problem on pavers. Give it a try and let us know by posting a comment on this blog post.
We also use this on areas of the gravel driveway that are prone to growing things. It's level so we just let the rain wash it into the ground. It does better if you remove the plants that are already there.
