If you decide to use a torch to burn out the weeds, be careful around anything flammable, such as mulch. I've always been amazed that many of my friends don't realize that most mulches will catch on fire and burn. I had one friend put out a cigarette in one of my front flower beds, and it caught fire. I was lucky that another friend noticed the thin wisp of smoke rising from the bed several days later! My house could have burned down!
Another friend decided to bury her cigarette in one of the wood flower boxes on my patio. I kept smelling smoke, and finally looked out the back door to find the thing fully engulfed in flames!
Non-gardeners seem to think "the ground" won't burn. [img]https://bestsmileys.com/clueless/4.gif[/img]
