Yes Alison I have manyyears ago grown nymphaeas in Lilypons tubs and fertilised with Lilypons fertilizertablets for nymphaeas. I had good results but the fertilizer tabletsneeded to be applied too often and I have a million other plants to lookafter. The shallower tubs are good, and similar to the washpans I amusing. Both the washpans and the pig manure are far cheaper than Lilypons products.

John,

I have grow water lilies and Lotus fordecades using water lily

pots. There are many sizesavailable of these from suppliers

such as "Lilypons".

Also, while I'm not advising on a mediumfor aquatic aroids, I

can confidently report one of the bestmedia for Nymphaea or

Lotus is the heavy red clay soil of theUS Southeast. Also, the

muck in the pond is called muck and madeup of more than the

fish waste ... the roots of my plantslove it as well when it has

accumulated enough :-) .

We cover the top of the clay soil in thepots with gravel. The aroids

along the margins thrive in this.

Have you tried these water gardeningtechniques and have you

read any of the information fromLilypons?

I would love to hear.

Alison

I have had very varied success with Nymphaeas. The books saylarge containers with no holes and NO animal manure; only good topsoil. Then you have to keep giving fertilizer (the Nymphaea fertilizer is EXPENSIVE)or the plants start decreasing in size.

But I observed that a yellow nymphaea which had grown over the edgeof the pot, had sent roots spreading in all directions in the gunk on theconcrete floor of the pond (largely fish excrement). And the lily wentwild! Huge leaves and flowers.

So I started putting nymphaeas in fairly wide, but very shallowplastic containers, reasoning that the roots like the aeration on the surfaceof the soil medium. I use cat litter trays or shallow “washpans” (pre-washing machine). In the bottom I put 4 inches ofwell-rotted pig manure, topped by 4 inches of loam. I plant the nymphaeain the centre and cover the loam with sand. Then I gently submerge thecontainer in the 18 inch deep pond, but not keeping the crown 6 to 8inches below the water surface, as the books tell you to do.
