Most of the hardy waterlilies are in one gallon pots. Some of the tropicals are, but most of them are going into either 4 inch pots or 18oz plastic cups, ala' Shawn.
With both, I'm looking for tuber production, more so than blooms, this year.
As for fertilizer, they all get a dose of Red Diamond prills in the bottom, with a regular "pond tab" as a "jump-starter." I'm experimenting with the Red Diamond, and have already decided that the label instructions of 3/4 cap full per gallon is kind of light and will be using a full cap full in those one gallon pots, maybe more.
Right now, my major concern is probably the same as most of you, pond space! Running low on funds so I'll be putting up some kiddey pools until I can get more grow out ponds up and running.
It's fun, but HOT out there!
