How to Remove Weeds from Sidewalks

I was watching my neighbor dousing the weeds in his front walk with one of those jumbo jugs of weed killers. You know the ones I mean, where it's not just a little spray bottle, it's now a spray nozzle connected via a thin hose to a big ol' jug of chemicals? Yikes.

Anyway, I was watching him getting all weed-killer happy on the spotted spurge in the cracks of his sidewalk (incidentally, he was using enough weed killer to exterminate an entire football field of spurge) and I was thinking that for the amount of money he paid for that jug-o-chem, he could have bought himself a couple of vegetable starts instead. Weeds that grow in sidewalk cracks are really not all that hard to get rid of. Like most things related to gardening, it takes a little bit of elbow grease and a bit of staying on top of it before it becomes a bigger problem.

Here are a few chemical-free ideas for getting rid of sidewalk weeds:

• Use a flat-head screwdriver or a dandelion digger to scrape them out.
• Boil water and (carefully!) pour it on the weeds.
• Make a simple spray with 1 quart of vinegar, 1/4 cup of salt, and 2 tablespoons of dishwashing detergent. Stir it all together until the salt dissolves. Add it to a spray bottle and spray directly onto the weeds. This works best when there's no rain in the forecast for a couple of days!
• You could flame them.
• And, of course, you can pull them. Pulling is especially effective for roots with taproots, such as dandelions.
