Tracy, that area where the offshore lilies are growing is on a big flat. Before all the rain we've gotten over the last 4 years, we used to walk out there and fish so it was easy to plant them, but it was just a shot in the dark to see if they grew. It'll be interesting to see how big that batch gets with no limiting factors other than rain.
I haven't tried to control any lilies yet. If I do need to trim them back, I'd probably do it in the fall, and just use a weed razor to cut the stems off near the bottom. Just a guess, but I would think that the tubers would need to be cut to properly treat just a section of the lilies. Maybe a drag with a blade on the bottom using a tractor or truck to pull it back to the bank? Now you've got me thinking.
