It got to be too much to use the tea kettle to boil the weeds in the patio and gravel driveway. I went to home depot and bought a pump sprayer that is meant to hold bleach but I poured in the cheap white vinegar I bought for 99 cents at Shoprite. Worked like a charm! DH came home said the garage smelled like salt and vinegar chips. Since it hasn't rained the driveway still smells of vinegar but no more weeds!!
Anyone else have any environmental green weed killing ideas?
