No problem, the well pump supplies the fountain, The plants you are talking about are dwarf musa cavendish bananas, I have to dig them up ant put them in the grenhouse for the winter as they would die if I didn't I also grow them in the large greenhouse and have one blooming now should have fresh bananas in January! Yes I put the galvanized bolts through the pipe drove 2 pieces of rebar into the ground in the center of the pipe and then filled with concrete. Very sturdy and will never rot. I had to raise the dock because the wood is about 3 inches under water when I am at full pool. I am getting ready to dig another well so I am able to keep it full the well I have is too slow but will have to wait until after I buy the new 10 acres. I am about 2 ft low right now but have only had 1.5 inches of rain in the past 60 days. Looks like my sister in Virginia Beach is gonna get my share today! I believe you are in the same zone 7a as I am so you might be able to get away with leaving EE's in the ground I would get a few in the spring and give it a try. They look real good lining the pond where I have them.
