Living in a temperate climate that basically gives us a tropical sumer has it's advantages. one of these is water spinach (ipomoea aquatica). I can get this from a local farmers market, but would rater grow it myself.
My wife puled the leaves off for a meal and stuck the stems into the mud of our small garden pond. They have taken root and put out new leaves. The concern I have is that we got them out to late to get more than another meal or two before it gets too cold.
if citrus can grow in the alps, I should be able to find a way to grow water spinach here. The problem is that this is obviously a frost pocket. I realize that the water will give off heat for a little wile, but the heat will be gone soon after the cold comes. I might try to over-winter some indoors for "seed stock", but it would be awesome to grow it outside all year.
How can I design a system that would allow for that? Any thoughts would be much appreciated. I will try to get some photos up later today.
I grow water spinach year-round indoors in my hydroponic Tower Garden. It-re-roots easily and grows fast.
I don't have any experience growing it outdoors, but most sources list it as extremely frost-tender, likely will need to maintain above 40F and it will stop or slow any new growth if it gets that cold.
You could try some Eliot Coleman-style winter techniques with a plastic hoop over row covers, but I expect limited success with this tropical plant in Tennessee, where it hit 5 or 10 degrees every winter.
