Three things I wish someone had told me before growing Cattail
After growing Cattail for over a year here is what I'd tell a beginner.
First: dividing overcrowded plants every two or three years in spring is not optional — it's the foundation everything else depends on. Second: root-eating by water lily aphids or china mark moth will happen and you should know how to handle it before it does. Third: a stream edge or bog garden genuinely matters — the right position unlocks natural filtration improving water clarity and quality in a way a poor position never will. overwintering dormancy in the pond bed is the payoff for getting all of this right. It's worth every bit of effort.
