Monday afternoon The Engineer I were entering our subdivision and we saw a pillar of smoke three blocks from our house. We drove by and noticed all the neighbors were out so figured 911 had been called. About half a block later we heard sirens.
Our neighbor is a fireman and he came over last night to fill us in. The homeowner had gone outside to smoke and put out the cigarette in potted plant. It turns out potting soil is flammable - with wood chips, Styrofoam and fertilizers.
The homeowners wicker furniture caught fire and the fire went into the attic. The whole ceiling was waterlogged and came down.
Fireman neighbor says they have about 4-5 potting soil fires a year in our community of 33,000.
