I have a tropical water lilly that was kicking out pads at a fast rate I had it on one of my planter shelves at about 16" deep. My other lillies are hardies and are all over 4 ft deep in the bottom of my pond. When I dropped the hardies to the bottom all the pads made it to the top within 3 or 4 days. I thought the tropical would do the same so I dropped it to the bottom and even after 4 days the pads were not even close to the top. The pads stayed under water too long and the koi started nibbling and they started turning black. I then pulled the tropical back to the shelf it was on before at the 16" mark and trimmed off all the beat up pads. It has been about 2- 2 1/2 weeks and this lilly has not put out one pad. It was doing so well before shooting out so many pads. Did I put too much stress on it by dropping it? Will it come back and start putting out pads again or is it done? Thanks you!
