  • One natural method is to pour or sweep into the cracks "corn meal gluten". Not "corn meal", which is the entire ground kernal. Corn Meal Gluten is the bright yellow, protein part of the corn. It acts as a natural preemergent and should inhibit weed or grass seeds from taking root. However, it is also a great fertilizer with its nitrogen content. So, any plants which are already growing will brighten up. This is used on lawns with great success. [You will also notice an increase in earthworms as you go more the natural way on your lawn and away from the very toxic chemical fertilizers and herbicides.] To kill already growing grasses in your cracks, spray vinegar mixed with orange oil and a little soap (the 10 percent vinegar with an ounce of orange oil per quart - add a little liquid soap). Spray the plant on a sunny day. Another method to kill already growing grasses is to cover the plant area with sugar or molasses. The microbes in the small soil area will "go into overdrive" and burn out the plant. Another method to kill some weeds in the cracks is to cover a moist plant with cinnamon. Cinnamon will also deter bugs. You will find information about orange oil and its uses on some of my other answers. NEVER use Roundup or other herbicides. Their toxicity is dramatic and will poison your lawn and family and pets.
  • Simplest remedy I know is to strain your pasta (yes, I said pasta) into a large container when you've cooked it and pour the resulting hot, salted water carefully on the crack that has the grass growing in it. The near-boiling temperature of the water kills off what's growing and the salt in it (I presume that you salt the water in which the pasta cooks) penetrates and inhibits new growth. Of course, the neighbors DO think you're crazy, but it works!
  • I don't like to use chemicals so I burn them with a blow torch. Works well. They actually sell landscaping blowtorches with a special adapter.
  • I hit them with a blow torch on a sunny day after a rain.
  • two things can be done for a long term cure. on is to power was the current sand out besure to let the joint completely dry then once dried sweet in a polymeric sand. the polymeric sand has a bonding agent in it adn once it get wet it acta almost as a mortor this also solves the problem of sand washing out. because of how firm the polymeric sand gets it wont allow seeds to germinate in the joints. the other option is to make sure you joints are filled with sand and the patio is clean and then apply a concrete sealer. the sealer will help bond the sand together, however its not as strong at the polymericsand but the sealer also protects the paver from staining. or for double protection apply both methods. just insure all plants or out of the joints when starting either one
  • I don't like to use pesticides so I pour salt in the grooves it kills and stops regrowth
  • Salt it. Usually absorbs better when mixed with water and a few drops of soap.
