Brick patio: weeds out of control

[Mitch]

I have a 1,200 sq ft brick patio. The weeds are rampant. I have to spray the entire patio with Roundup every 2 weeks.

Is there anything I can sweep into the cracks to keep new weeds from germinating?

Got a propane torch? You don't have to burn them to a crisp, only wilt them. They'll die.

Interesting. Just water it in?

[Dave]

If you want to do that. Not needed though. Any moisture will leach some salt and carry it to the roots of the plant. Very few plants will grow in a high salt (sodium) environment. Dave
