Vinegar and salt weed killer recipe in the link... Very effective. http://www.hgtv.com/outdoors/gardens/planting-and-maintenance/make-your-own-natural-weed-killer

Boiling water or vinegar. Salt-we won't go there, it is not environmentally savvy. It is raising the salinity of all the fresh water streams and lakes and causing changes to the natural flora and fauna. It does not disappear ever and just keeps building as it is washed into the water through the soil or run off.

Go to the grocery store and buy Pickling Vinegar - same area as the regular vinegar. It’s inexpensive and works! You need no recipe such as adding salt and blue Dawn dishwashing liquid - just straight Pickling Vinegar. I bought a plant mister at the dollar store and funneled some into it. Then at the START of a hot, sunny day, I spray the weeds that pop up between my patio pavers. The combination of the hot sun (all day) and the strong vinegar burns the weeds.

Be sure to avoid the lawn, shrubs and flowers! I do this about once or twice a week. If I miss a weed and it has time to produce a few good sized leaves, I sometimes will rip off a few of the leaves so the vinegar spray has a better chance of hitting the weed and seeping down into its roots.

Easy to mix...1 gallon of water, 1 cup of table salt, 2-3 drops of liquid dish soap. Spray onto tweeds during hot part of day and allow to dry thoroughly. Within 1-2 days, weeds will begin to turn brown and die. This will also kill grass and plants so be careful not to get it on things you want to keep.

hot water and/or salt in between the cracks should do it

I boil kettles of water and pour it in the cracks. It works.

You can also use white vinegar.

Thanks Elaine.
