    Do that in the Spring. Dig up the corms and gently pull them apart. Replant at the same depth they were in the clump.

    The corms form a chain, the uppermost corm is the youngest. I usually discard some of the older corms.

    Might be complicated for you Verdun, but not for me. Anyway you can't divide a Crocosmia plant, because a plant is a single cormimage

  • I call them zombies - previous tenants had them in a part of the garden where I didn't want them. I tried to get rid of them, but the tiniest bit surviving in the soil would become a 12" clump by the end of the following season! I have dug up such clumps, chopped them into bits with a spade, and given the portions to various friends who now have zombies in their gardens too. I have to say, these are the common-or-garden orange ones (sorry proper gardeners - I don't know what they're called) so varieties might be more sensitive, but if you've got the orange ones, dig 'em up, chop 'em up and replant.

    I've been trying for thirty years TTC image Crocosmia aka Montbretia! Thugs!

  • They grow like weeds here in Cornwall, in gardens and on waste ground, hedgerows etc.  You can have too much of a good thing in some cases and common Crocosmia/Montbretia certainly come in this group as far as I am concerned.

    I think that there is a massive difference between Montbretia and some of the more delicate Crocosmia, that multiply very slowly and are slightly tender in my part of the world. They need to be cosseted.

    Thanks to all who responded to my crocosmia request.

    Im now much better informed on how to proceed Although I love my crocosmia I am wary of them getting out of control now. Will keep a careful eye out for excessive spread!
