The best way to prevent weeds is to use polymeric sand, which hardens and blocks weed growth when activated with water. If you're using regular sand, you'll need to refill and compact it more often. Keeping the surface clean and free of debris can also help prevent weed seeds from settling in the joints.

There are many options to eradicate weeds right down to the roots. Vinegar works, but it takes a week or so to do its thing, and the same goes for many commercially available herbicides. Boiled water is a quick way to kill off roots, or you can pull up weeds at the root.

Noxious weeds can be poisonous or act as an irritant to humans, but not all are directly harmful. However, indirectly, noxious weeds also compete with native species, effectively affecting our local ecosystems of plants, pollinators, and other animals.

There are organic herbicide options that will kill grass but not flowers, including white vinegar or a dish soap solution. Commercial selective herbicides can also target grass over other plants, but read the instructions carefully to avoid damaging your garden. Herbicides that kill grass but not flowers usually include ingredients like clethodim and sethoxydim. Otherwise, your best bet will be to weed by hand.
