Well FWIW... We bought about a hundred pines last spring that were 10 to 15 foot tall and had them transplanted. After doing some research, we bought a Honda gas water pump and a whole lot of hoses. It is a 2" pump with the outflow split into two water hoses via some fittings. We don't crank it up full blast; but it seems to work pretty well. It really isn't that big or heavy. We haul it to the pond with a Rhino. Probably have about 500 feet each of 5/8" and 3/4" hose. Am amazed at how much more water the 3/4" hose seems to put out. Also, amazed at how noticable the extra weight of that hose (full) is when moving them. Overall, I think it was a good choice.
