Here is also another home made less toxic weed killer since it is garden season.
Homemade Weed Killer
by Rachel Paxton
When I saw this article I knew I had to give this natural weed killer a try. It is very inexpensive, non-toxic, and yes it will kill your weeds.
Here is what you will need:
1 gallon of white vinegar
1/2 cup salt
Liquid dish soap (any brand)
Empty spray bottle
Put salt in the empty spray bottle and fill it the rest of the way up with white vinegar. Add a squirt of liquid dish soap.
This solution works best if you use it on a hot day. Spray it on the weeds in the morning, and as it heats up it will do its work.
