Pond Irises
Hi All,
I've got some irises in my pond. They grow well enough, perhaps two feet tall, but they don't flower well. Most of them don't flower at all, if they do, then they put out plenty of buds, but then the buds turn crinkly and don't open properly. https://www.dropbox.com/s/bikvkjfue1...47_01.jpg?dl=0 What am I doing wrong? Thanks. |

Thanks. Think it may just be bad luck with the weather, our native yellow iris doesnt hold its flowers very long and if the weather is wet and windy they can come and go in a day, similarly if its very hot. 2' tall is very short, have they got enough root space? -- Charlie Pridham Gardening in Cornwall www.roselandhouse.co.uk |

I've just re-read the text on that first link, where he says the irises are OK, but I'd still check for evidence of lily beetle. Irises aren't affected by lily beetle. What they do go for, if they can't find lilies, are fritillarias. They can decimate snakes-head fritillaries almost as quickly as lilies. I stopped growing lilies because of them, but I'm trying again. I do have a yellow lily which they don't touch. In my experience, the insecticides available to the amateur said to treat lily beetle are a waste of time and money. Only dimethoate used to be effective, but that's been gone for years. -- Jeff |

It's hot at the moment. I don't think that the flowers are coming and going quickly, it's more like they go before they've come :-) 2' tall is very short, have they got enough root space? It could be that. I've just been out to count them, there's six or more in one kidney shaped pond plant basket. Do I need to take it apart and re-pot everything? When is a good time to do it? A few years back, one of them climbed into the next door pot and rooted, I separated them a couple of years back with loppers, was that an indication that it was getting crowded? I've got a green fibreglass pond, two feet deep. The pot is on one of the shelves (~9 inches below the surface), will it be ok if I put it on the bottom? Thanks. |

My Pond iris are all in about 25 lt containers (I make them bags out of ground cover fabric) the soil level needs to be near the surface, I dont have any detailed pictures but below is a pond pic from a few years back http://www.roselandhouse.co.uk/house4.htm -- Charlie Pridham Gardening in Cornwall www.roselandhouse.co.uk |

They need to be planted at or better slightly raised from the water level. They are bogs plants not water plants. Myself I would throw those common native iris away and get some nicer iris, the Japanese ones are all superb and come In a range of colours. Iris Siberia can take wet feet too. -- Regards Bob Hobden |

Your pond irises are marginal or bog plants, and should be either in very shallow water or boggy soil clear of the water. Ours have escaped into the flower bed next to the pond. It's quite damp at times - and floods in winter - but right now it's solid clay. And they are flowering nicely. Unlike the fancy irises at the end of the garden, where for the 3rd year in a row the flower buds have rotted before they opened properly, all crinkly inside. Which sounds just like the OP's problem... I've been meaning to post some piccies. Andy |
