Nedoc...I'm flattered to have an interested party in my "stuff". I enjoy compiling it, so enjoy!
I did find an article where hyacinths were used to battle high nutrient laden/polluted waters...
"STRIKING A DEAL WITH THE WEED FROM HELL" by Garry Hamilton
https://www.conservationmagazine.org/2014/03/water-hyacinth-in-kings-bay/The above article says that they used the WH to cover about 1% to 7.5% of the water's surface in multiple Large BOW's and recorded very good results. Some of the results were argued, but it's all I have found to base my little pond ramblings on.
At any rate, 7.5% coverage on my 1/4 acre pond amounts to about 1100 square feet. That equates to 11 of my 10 foot square corrals. I don't think I have it in me to spend the additional $400 for the corrals, sacrifice the surface area of my pond, dedicate a boat for maintenance, spend the time culling plants, etc, etc.
But 1% of my surface are is just a bit larger than one of my corrals. So, I will stick with my original plan and count on making a second corral should this one fill up quickly and reap arguable results all the while enjoying the flowers. If this one corral does not fill up quickly, I will throw and extra $20 at plants at the beginning of next season.
On a side note: dlowrance (fellow PB member) has stated that his WH (located in central Illinois) come back every year from seed (some years more so than others). By my estimations, him and I are in the same plant hardy zone (or very close). Next year will will be interesting at my pond to say the least to see if these crazy plants make me crazy (er). And, anthropic can tell me "he told me so".
Here's the thread where Dale talks about his WH...
