Hi, I bought 3 Iris Kermesina plants about 3 years ago and so far - plenty
of leaf but no flowers.
They are planted in a 6 inch deep trough and the top of the trough is about
4 inches below the water surface. This is a smallish variety and will grow
to about 12 inches above the water.
The 'pond' is plastic pre-moulded, 3 feet x 2 feet x 18 inches deep. There
is no pump/fountain/filter etc or fish in the pond and most of the other
plants have been doing ok. Any ideas please ?

Pete

I would raise the plant up a little in the water. Also, the lack of
fish may mean that there isn't enough fertilizer, unless you also add
that. The other plants may just not be as heavy feeders. You don't
say what they are, so it's hard to say, but that may be it. I just
noticed that you said most of the others are doing fine. Those that
aren't may also need a little feeding. Others here may know more, but
that's all I can offer, except that if you go on gardenweb.com, there
is an iris forum and a UK gardening forum. Someone over there might be
able to help if you don't get what you need here. Good luck. I like
irises too.

========================
I would guess they're lacking phosphorus. A few fertilizer tabs should do
the trick. They may also want to be closer to the surface.

I was thinking phosphorus too. I remember from my rose days that some
plants need quite a bit to flower well.

The first 3 are native : Lemna Triscula (Ivy leaved Duckweed), Eleocharis
Acicularis (Hair Grass), Nymphoides Pelta (Water Fringe), Scrirpus Cernuus
(Fibre Optic Plant), Lagarosiphon Major (Elodea Crispa), Azolla filiculoides
(Fairy Moss) and Aponogeton Distachyum (Water Hawthorn).

Thanks all, I will raise them and get some food tabs tomorrow.

Also keep in mind, you can't divide iris till after they bloom, otherwise
they may not till the next season. ~ jan
