I'm not aware of any home remedies you can make to kill weeds selectively over a large area. For weeds growing up through the gravel you can try spot spraying them with vinegar (vinegar is not selective though, so be careful). You need a hot sunny day for this for it to be really effective. You could also burn weeds with a propane torch. This method seems to work really well for weeds in gravel driveways or paths. Pouring straight Epsom salt on some weeds will turn them black and kill them over the course of a few days. Another strategy is to prevent weeds from germinating by applying corn gluten meal to the area. This is a natural corn by-product (usually used in animal feeds) that provides pre-emergent weed control by interfering with root development. You should be able to find it at feed stores and some garden centers. Corn gluten meal is also non-selective, so you need to time application with when your weeds normally germinate. It won't harm already planted grass or bulbs (in fact it's a great lawn fertilizer), but if you planning on re-seeding your lawn or planting flower seeds in the area you'll need to wait 6 weeks. It's usually applied at a rate of 2 lbs per 100 square feet and provides 6 to 8 weeks of control.
Hormoban is a selective spray. It will kill the weeds but not the lawn, trees or anything else you want to preserve.

I have a beautiful gravel driveway but the weeds are driving me crazy (no pun intended). Do you have a low cost solution?

I find that pouring boiling water on weeds helps to keep my gravel driveway quite clear. I attack them as they appear so they do not get a chance to take hold. Best of luck.
I have used the vinegar, but I used plain old kitchen vinegar. Just bring it to a boil to concentrate, let cool, put into a spray bottle. I also add some undiluted lemon juice with the vinegar.
All you have to do is dissolve ordinary table salt in some water and pour it onto each weed - make it quite strong though. I used to do this on our tennis court where the odd weed came up and it works like a charm. Happy weeding!
The best non toxic thing to use is Vinegar. Not the stuff you get @ the grocery store but @ the garden center. It is 20% vinegar. It works well and it is not picky about what it works on so be careful not to spray plants you want.
I use epsom salt to kill plants
Pour on plain old table salt - right from the package. cheap and effective.
I vote for vinegar too.
Buy a 4 litre jug of vinegar and remove @2 cups.
Add 1 cup salt shake and use to spray on weeds.
It will kill anything it touches, so be careful.
If I do any of these tips... will I ever have to 'reapply' again or would this be the only time? I want to take care of this and not add this to my yearly 'To Do' list.
