Here's a simple, inexpensive, organic solution for eliminating pesky weeds that invade those spaces wherever they can find a patch of gravel, cracks in concrete or asphalt, spaces between pavers, bricks and stones:
Simply bring water to a boil in a tea kettle or pot with a handle, carefully tote it to the area where weeds are invading your driveway, walkway, garden path, porte cochere or courtyard. Pour the boiling water over the weeds, letting it seep into the ground. The weeds will immediately begin to shrivel all the way down to their roots. Within a couple of days, you can sweep away their dried leaves and pull out the dead roots with ease.
