Dividing Crocosmia (Montbretia) in Pots | How & When to Divide Crocosmia | How to Split Crocosmias

Crocosmias are the highlight of a late summer border with their bold bright colours and striking sword-like foliage. We love them and have many varieties in our garden.
In this video we are dividing a clump which has been growing in a container, and removing the old corms to rejuvenate the plants for better flowering next year.

    FINALLY, an answer! I had to dig up my crocosmia as it was very root bound. I noticed that there were three corms on top of each other. I wanted To replant them because they are absolutely gorgeous But the other videos that I watch never said how to replant them especially If the bulbs were on top of each other so now I know What to do and I thank you so much for saying That you remove the top bulb and discard the others. Thank you. Again, so much. Greatly appreciated

    Hi Paul and Andrew, Thanks for showing us this. I always learn a lot from you. I didn't know about discarding the old corms as I assumed they would sprout as well as the new corm but when I come to repot mine I'll do this. I had a massive clump in my old garden and it was a bit invasive so I've always grown them in pots in this garden. I didn't get many flowers this year and put it down to the hot summer weather. Now I know that they probably need refreshing. Thanks for your last message. I can imagine that the editing takes skill and time. I wouldn't know where to begin as I'm useless with technology! Take care.

    Hi Wendy. Thank you such for your lovely message. You are very welcome. We are so happy that you have been able to take something from the video. Its true and most people do not realise that they not only need dividing, but they appreciate the old corms being taken off too. They are such beautiful plants though, the foliage is gorgeous, but nothing can beat those vibrant flowers. It could have been the sun, as so many plants have suffered this year, but have a go at dividing and taking off the older corms and see how they do next year. It's well worth it. The amazing thing about gardening is it's like life, we learn by experience and from eachother 🙂🤓🌹🪴 Have a great day Wendy from Andrew and Paul.

    Useful advice, as always. I always break off and discard the old corms, but on Gardeners’ World last Friday, Monty Don just divided his up and did not remove any corms. Not what I do, so you have reassured me. I’ll carry on as I always do, as you do too.

    Thanks for your comment and kind words about our videos. I too noticed Monty didn't remove the old corms and said they flower better if conjested. We've never had any problems with our method, in fact, the very reason we were dividing the plant in the video was because they hadn't flowered very well. We will keep doing what works for us, you too. Thanks for watching 🙂🤓

    Great vid, short at to the point. I too thought the ones underneath could be split and grown separately, but obvs not. So do the corms multiply side by side, or do they just grow down, so there is no actual net increase in corms, you are just getting rid of the old ones, a bit like deadheading, but underground.

    Many thanks! Each year they produce another new corm on top of the old ones, but they also produce new smaller corms by the side of the corms too, which can be separated and grown on to produce flowering plants within a year or so. The underneath corms will grow but they won't be as good and vigorous as the top ones. They can however produce new corms so can be used to increase numbers too.

    I found some crocosmia growing in a discarded plantpot behind my shed - I had weeded it out and just left it there - then one day I noticed it had produced these lovely bright orange flowers right at the edge of the container - it had another pot on top of it too - amazing how nature can win sometimes - there's 3 of them still at the edge of the pot they've died back now so I'll have to have a look and see if I can help it along by pulling any extra corms off - I have no memory of planting it 🙄🤷

  • @MadAboutGardening

    @MadAboutGardening

    2 ай бұрын

    If its bearded iris, these grow from rhizomes which need to be baked in the sun in summer which is why they need to be planted with the rhizome above the soil. If you never get flowers they may be too overcrowded and/or not getting enough sun. If you want to divide them, it's a case of slicing up the rhizome into smaller pieces each with a fan of leaves and replanting on a ridge of soil with the rhizome out of the soil. Cut back the leaves to prevent to wind dislodging the plant while its reestablishing. This ideally should be done after flowering or after they should have flowered in mid- late summer. Hope this helps 👍

    are those discarded corms going to form a new plant? how likely is it that a discarded crocosmia root is going to grow a "volunteer" plant? say if I composted it or threw it in the garbage and it went to the dump. Will it form a new root and possibly become an invasive plant? The runners my potted crocosmia produced resembled those of some grasses that have made a nuisence of themselves in the community garden. I got my first crocosmia last year, pretty sure it was a lucifer. I brought it in in the winter hoping for flowers but it went dormant with just some pretty grass like foliage. I figured it would start back up again in spring and it was like amaryllis where watering controls its dormancy triggers. Then it started growing out of a crack in the plastic pot in mid december and I went "uh... oh..."

    The discarded corms may try and grow but will never produce very healthy plants because they are old. Crocosmia x crocosmiiflora is the plant that is invasive, the ones we grow in our garden are clump forming varieties that are not invasive but its a good idea to dispose of them rather than put them on the compost. Crocosmias are herbaceous perennials, which means they will die back in winter and regrow in the spring, sometimes before as ours are already producing a lot of leaves. They flower around mid/late summer so you'll get to see it in flower then. Lucifer is a tall fiery red variety and is easy to identify.

    We don't have a video about Crocosmia seeds (yet!). We'll have to check if ours are ready to collect. When the seeds pods begin to open to reveal the seeds, collect them by gently releasing them from the pods and put the seeds into paper envelopes. Store in a cool dry place until the spring and then sow them. Hope that helps 👍

  • @MadAboutGardening

    9 ай бұрын

    Yes, Montbretia is the common name for Crocosmia, but it used to be restricted to the invasive hybrid Crocosmia × crocosmiiflora. If you want to sow the seeds of Crocosmia, they should be sown fresh when they are collected in autumn and left to germinate somewhere warm. Keep seedlings frost free until the spring and when large enough plant out. It may be several years before they flower and the plants may not be identical to the parent. To get identical plants it's best to divide. Hope this helps.

    You can divide either spring or autumn although I'd wait until autumn now as you will probably affect the flowering if you do it this late in spring. Wait until after the plants have flowered this year and then do it 👍

It's a vigorous orange flowering plant which is classed as an invasive species in the UK. If this is what you have the best disposal is in landfill through your local waste service. The only way to completely remove it is by digging it all out.
