Subject says it.

We have a yellow-flowered pygmaea lilly in a half barrel. First year, it
did very little, 2nd year it flowered well but for last 2 years,
nothing. It seems very happy - lots of leaves but no sign of a flower
bud. There are quite a few frogs, toads and newts using the barrel but
no fish.

Any suggestions, please.
