What happened to my water lily?

catherinet(5 IN)September 28, 2013

I have in inground Rubbermaid stocktank pond (300 gallon).
I had a waterlily in there that I had divided just last year. Also in the pond were 2 water irises......one of which got way too big over the summer.

I think I lost a fertilizer tab into the water, while feeding the water lily. Then duck weed went crazy. Then the water lily totally quit........maybe put out 1-2 leaves, but no blossoms.

I cleaned up the pond today. There were alot of tadpoles, which should have eaten the duck weed.......not sure why they didn't.
Question: Why did the waterlily poop out? When we pulled it out (was in a 7 gallon container), half of the container was still dirt.....no expansion of the water lily. There was a growing point putting out little leaves.

Could the overgrown water irises have been taking all the nutrients away from the lily? Could the duck weed covering the entire surface have shaded the lily too much?

I've been growing lilies in this pond for quite awhile, and I've never had one act this way. Never had such a huge water iris in with it either.
I had been fertilizing the lily ever 3-4 weeks, prior to it pooping out.
Any ideas?

My guess would be that the growing point was damaged somehow. Another thought would be some sort of larva inside the tuber but those might have affected the iris too.

Thanks Sandy. I guess I'll have to wait until next year to see if it grows better. It was beginning to make some baby leaves, so it does have an least one growing point.

I had water hyacinths in my pond this year for the first time with my water lilly, and it didn't spread like it usually does, it did bloom, but no spreading, I think it was the hyacinths.
The water iris I have is not invasive, so it really didn't bother the lilly.
I only fertilzie the lilly once in spring with tomatoe spikes in the clay in the pot. It bloomed all summer.
I am not placing water hyacinths in the water next year.
I'm going to let the lilly spread out a little more. I think they do affect the sun hitting the lilly through the water.
I could be wrong, but I did notice a difference this year.
