Recently I learned something new about using vinegar to kill weeds,
For several years I have used 30% strength vinegar in a ‘chemical resistant’ spray bottle to spot spray weeds. This is a very effective weed (and grass) killer.
This spring I sprayed some weeds but the result was not what I expected. The weeds stayed green and growing.
Turns out that the acidity of vinegar declines over time when exposed to air. The vinegar I used this spring was a bit left in a gallon jug that I purchased last year. A few days ago I bought a new gallon jug, sprayed some weeds and they died just as I expected.
If you want to try this, do not use grocery store vinegar. It is not nearly strong enough. I buy mine at the local big box lumber/hardware store. Make sure what you buy says 30%. Look for it where they have cleaning supplies. And if you use a standard spray bottle then the acid will destroy the spray mechanism after a bit. That is why I use a ‘chemical resistant' spray bottle.
Also, when I spray this stuff I am wearing rubber gloves that come halfway to my elbows.
