A walkway free of unsightly weeds can make all the difference in keeping your home’s landscaping looking well manicured. The way a stone or block walkway is installed can limit some weed growth in the cracks. A layer of landscape fabric beneath the pathway prevents weeds. The fabric is held in place with U-shaped stakes and covered by sand or gravel as the base for the walkway. Another preventative measure is to use polymeric sand between the rocks instead of regular sand. When dampened with water, the polymeric sand solidifies with some flexibility in the joints. The solid nature of the sand makes it difficult for weeds to protrude.
That being said, weeds are extremely aggressive and can still be a problem. Also, grass seed applications that carry over to walkways can cause grass to start growing in the cracks. There are many commercial chemical applications sold to control weed growth, but the eco-friendly homeowners of today are now going toward more earth friendly options. There is an all natural solution that you can mix up to kill weeds in a brick walkway that is safe for children, pets, and won’t break the bank.
The recipe for natural weed killer is simple. Combine 1 gallon of white vinegar with 1 cup of salt and a tablespoon of liquid dish soap. The soap is a wetting agent that helps the vinegar and salt mix. Stir it all up and pour or spray on the weeds. Use this and you won’t have weeds for 3 to 6 months. Don’t get this natural weed killer on any plants you want to keep because it’s actually a soil sterilizer. It isn’t selective and could harm shrubs and your grass!
To avoid damage to grass, consider “painting” the vinegar directly onto weeds with a brush. If you do spray with vinegar, don’t pull the trigger until you’re right up close to the targeted weed. Don’t spray on a windy day, as the wind could carry your vinegar spray where you don’t want it to go — on your grass.
