when transplanting a lot of duckweed, ive laid a tarp down on a trailer, put a lot of duckweed on top of it, made sure it was good and wet, put another tarp on top and went with it. obviously i would try to get it there as fast as possible, but i would try not to let i dry out. although, i have seen some that dried out on the bank when water level fell, water level rose and it turned back green again. Some ponds ive transplanted to, it didn't grow at all, and others it exploded in. the water has to be right. under optimum conditions(fertility, ph, and water temp) duckweed can double in surface area every 2-3 days. It may be illegal, but what isn't these days. When will tpwd starting harassing and ticketing ducks, cranes, water turkeys, etc for transplanting?
