Dividing Irises
Can anyone advise me how to (successfully) divide an iris clump. Someone
told me I need to just stick the spade down the middle and pull the 2 halves apart, then plant one half elsewhere! Sounds a bit brutal to me. I'm frightened I might damage the plant. Any advice would be appreciated. Jo |

Dividing Irises
I agree with Bob but Irises should be split straight after flowering,
also shorten the foliage to 3-4 inches above the Rhizome as this stops them drying out and allows the roots to get going in the new area you are planting them in. When replanting them don;t bury the Rihzomes to deep as the Rhizomes will root off, they like there rhizomes to be baked. Hope this help you, PS all Irses types like well drained soils.

Any advice would be appreciated. I presume you mean Tall Bearded Iris? Sounds about right. Usually in a clump the centre is old and leafless, throw this away and replant the young fresh outer bits, you can be quite brutal with them (use a sharp knife) and as long as there is some roots attached to the plant it should be OK. -- Regards Bob Hobden 17mls W. of London.UK |

I did exactly this last year based on what I'd seen on the telly. I also trimmed the leaves right down. I had no confidence that I had done it right but I had the best show of irises this year that there's ever been in the garden. If I can do it then anyone can. -- Paul C |

I was told to split them 8 weeks after flowering by a specialist Iris nursery which is about now. Anyway, as long as they have time to grow a bit by the winter and put some more roots down that will be OK. Incidentally, out of necessity we moved some of our irises from our old allotment to our new one after Christmas last winter and they still managed to flower a bit. I know everyone else cuts the foliage down but I usually never bother unless it's a very windy site and they would rock in the wind. The leaves are their power house. The last bit about sun on the rhizomes is very important and I usually try to point that bit towards the south and sun. -- Regards Bob Hobden 17mls W. of London.UK |

Then brush off the earth and pull the young growth from the old stuff (which should be composted),cut the leaves on the slant from about 3to 6". and plant shallow. Water in. I've had my irises many years and they always give a good show, |
