They need warmth to take off (and some potash if you have fish, full
fertilizer if not). They suck nutrients up like crazy - The University of
Vermont has even experimented with them in "green houses" to scrub sewage.
VT is too cold for them to survive in the winter and most lakes are too
cool
for them to spread very much in one summer. Thus they are no treat as an
invasive species in VT.


Where do you find fertilizer that has a low nitrogen and low phosphorus
content, and is fairly high in potash?
