Florist Waste Risk
Someone on another forum suggested florists as a good source of greens for composting, so today I stopped by two florists who said they could supply me with plenty. But . . .
The second florist questioned the safety of using florist waste. He said their plants come from everywhere: Colombia, Ecuador, etc., and in those countries they use pesticides that were banned fifteen years ago in the USA, pesticides that are residual and will not be removed in the composting process. This includes some heavy metals. These would remain in the ground for an indefinite time.
Does anyone KNOW what actual risks/dangers there might be? I am into big-time--at least for non-commercial--composting. This would be only one of my many greens.
On the composting forum I've already been told to stay away from it, but someone suggested that this forum might have experts who could give a definitive answer.
I've already abandoned the idea, unless someone can authoritatively tell me there is no danger to soil, plants, or whatever.
