I was following the rec.gardening newsgroup early last spring and there was 
a lot of talk about this very topic.  It was discussed in the context of 
killing the weeds and weed seeds.  Seems the consensus was that yes, it 
works, and that clear plastic was better than black (something about the UV 
light).  I don't remember (if I ever knew) how long it was left on but I 
would think it would take at least a week.

While I'm here, I do have a question I saw asked a month or so ago but 
missed the answer.  I just relocated offices from northern VA to southern MD 
and was off the net for a couple of weeks.  I have some very healthy looking 
i. pseudacorus and i. versicolor I got from Clarence Mahan and am wondering 
what to do with the seed pods (one of them is the size of a small banana). 
 I have them planted in a "water bog"  of gravel with water circulating 
through it from my pond.  Is it difficult to grow seedlings?  How do I do 
it?
BTW, the bog works better than I had hoped.  I have absolutely NO thread 
algae or suspended algae in the pond.
