I love to do things as organically and cheaply as possible.
I have learned a few new things I would like to share.......
Weeds
you can rid yourself of weeks by spraying them with vinegar. Tough weeds with long roots like Dandelion are a bit harder for this method but if you keep at them, they will go away . This will also kill grass so be careful where you are spraying - best to do it on a non-windy day.
Ants
Sprinkle corn meal where you see pesky ants. They will eat the corn meal but they can not digest it so they die. This is extremely effect.
