Very odd that you can not find a DW supply. If I had DW on my pond, I would insist that you come back every month all growing season long...all or nothing!

I suspect DW is a particular plant. I say this because some DW got into my pond with some plants I bought online and my heart sank. I found several little specimens floating around the banks...took out what I could, but surely did not get it all. That was over a year ago and no DW to date.

Can you get a handful from a pet store or water garden store and see if it takes to your BOW. If it does, it will not stop...if not, it may be a waste of efforts unless you are just wanting it temporarily for feed or draw in ducks.

Fish on!,
