Prevent Weeds From Growing


Q:  What can I use to prevent weeds from growing between my patio paving stones? There are fairly wide gaps between the stones so I get a lot of grass and weeds coming through. I have two dogs and a cat so I would like to find a solution that will not be harmful or toxic.

A: I receive a lot of requests for a homemade weed killing formula that really works for these areas; however, it is only recommended for driveways, sidewalks and patios. If you spray it on weeds in your lawn, you're going to kill the grass as well and create a big ugly brown spot.

Mix the following ingredients together:
- 4 cups (1 Litre) of white vinegar
- 1/4 cup (50 ml) of table salt
- 2 tsp (10 ml) of your favorite liquid dish soap
- Put this mixture into a spray bottle and spray it on your weeds when it's bright and sunny out.

Depending on how wide the cracks are you may want to consider filling in the gaps using a Foam Backer Rods available in different diameters.  First clean out the crack and wash with Shell Busey Home Cleaning Formula. Place the backing rod down into crack 1/8" from the surface.  Apply Weldbond or concrete adhesive over the foam backing rod. Allow to cure for 1-2 hours. Then apply Polyurethane caulking (gray or concrete color) into crack crevice so it sticks to both sides of the crack to prevent weeds.

Sprinkle dry sand over caulking and brush excess off using a paint brush. Allow to cure for 12 hours before using area. The end result will look like a real mortar grout joint.


It's Just That Easy.
