Safe way to kill weeds etc

A friend of mine wanted a safe way to get rid of the millions of lilac trees that had sprouted in the new house she had bought.  After searching a ton of different sites I found one that suggested Vinegar and rock salt.

It didn’t give you amounts just that if there was left over salt that didn’t dissolve after being left for awhile then you had enough.  What I did was every time I cleaned my coffee pot/kettle etc  I would put it in a left over vinegar jug that I had poured some rock salt in.  If the next time I went to put more vinegar in there was no  left over salt I added a bunch more.  I kept doing this all winter long.

Come spring in one of my flower beds there was this plant growing that I hated and it kept spreading…it seemed like the more I tried to get rid of it the more it spread.  SO I got a sprayer from the local dollar store and put some of this mixture in it and sprayed this plant and went inside for lunch. I came out about an hour and a half later and the plant had already started to die.  I checked it this morning and it was still very sickly looking but unfortunately it started raining so I’m not sure how it’s going to work.  guess I will have to see.

Next thing I’m trying this on is the wandering or wild grapes growing all over my trees.  I’m going to try drilling a hole in the stump after I cut it off and pouring some in…I’m hoping this will work.  I did it with a  couple of sycamore trees growing around here and it worked great.  I’ll keep you posted.
