My mom has a 3-4 acre pond on her property. Not realising it would spread, she put water lettuce in there 8 years ago. Needless to say, it went wild and went everywhere. At one point it looked as if you could walk across the pond - even though it was still 12-14 feet deep. 2 years ago it was poisioned - not sure with what, but it didn't cause a fish kill so I didn't really care (pond record fish is a 14lb bass a friend of mine caught in '76, and I pull one out pushing 10lbs every couple of years).
Now the water lettuce is growing back. What can I do to keep it "in control". I don't mind small rafts of it, as long as most of the pond surface is clear. We've had triploid carp and they didn't help, and we've tried physical removal (too much effort for no return), and I don't want to poison it again.
Any suggestions on early treatment, long term control, someone to contact, etc. would be appreciated. We're in N. Florida if it matters.
Thanks!
