    I'd love to grow some. I tried and failed a couple of years ago, so I might give it another go this year. We ought to give Snadger a shout, I know he grows them.

    Yes, I remember reading about it but couldn't find the thread when I looked last night. I think he was keeping them in the GH during Autumn/winter? I'm going to choose my varieties later. Looking forward to doing something a little different.

    OK well as I mentioned, I want to take cuttings from the yellow ones ("Bloom Gold" according to the label) that I've been growing in my back garden.

    My old book says that I should have lifted the plants (stools) after flowering and kept them in a frame away from the worst of the weather. As it happens I did that. But then it says I should cut off green growth and box them up in early January to encourage them to produce shoots for cuttings. So that's what I did this morning according to the instructions:

    - cut the old stem down to six inches
    - wash all the soil off the old roots
    - cut back longer roots back to six inches
    - cut off existing green shoots back close to the rootstock
    - replant in a deep seed tray in fresh compost
    - plant them half an inch deeper than they were in the ground, so that the cutting material will be white at the bottom
    - water thoroughly.

    The book says to keep them at around 50F until the shoots are growing strongly then increase the ventilation and drop the temperature to around 45F. I don't have facilities for this kind of precision, so I'm going to stand the box on my new heated propogator (with no lid) instead. They can come off onto the unheated greenhouse bench later on when they've got going.

    I fitted six plants into my tray, couldn't quite bring myself to cut off ALL the green shoots so I left a few baby ones.

    Let's see what happens over the next couple of weeks.

    My new ones from the nursery will be delivered in late Feb. Hopefully I should have some rooted cuttings of "Bloom Gold" by then!

    The rooted cuttings arrived in the post today, nicely packed and intact with just one snapped leaf.

    I've potted them up into a deep seed tray. I prefer this to using pots, they seem to develop a more extensive root system. I used John Innes #1 as recommended by my Chrysanthemum book.

    Meanwhile, my overwintered yellow ones are ready for me to take the first batch of cuttings. I'll probably do that tomorrow.

    And there it was, on the shelf right where it should be. I picked it up years ago in a second-hand bookshop in Brighton. It's called "Chrysanthemums for Amateur and Market Grower", by F.W. Allerton. It was published in 1949 (!) but I have the second impression published in 1950.

    Obviously some of it is going to be outdated (e.g. the introduction says at one point "Despite the fact that insecticidal practice has been entirely revolutionized by the coming of D.D.T...") I can't see how the principles of will have changed much.

    So I'm going to have a good read and see how much of it I can apply.

    I love old books.
    Hi Martin
    i have some now in cold g house from last year you have done well to keep them outside.
    Mine are still in pots i grew them in just cut them down at end of last year lots of shoots comming from the base now.

    Will have to take some cuttings soon, mine are sprays ,cuttings are like geraniums they root easily.
    like your yellow ones.

    Today I started taking cuttings.

    The plants I boxed up on January 10th have made good growth and I reckon there are 8 shoots big enough to use:

    My book explains that to take the cuttings you should cut the shoots off below the soil surface. This is because you want to end up with a quarter inch of blanched white stem at the bottom of the cutting. It also says to remove all but two leaves from the shoot to reduce water loss while roots are forming.

    Roots should form first from the white part of the cutting and then from the green part.

    Here's an unprepared cutting on the left and a prepared one on the right:

    The book says to dibble them into a tray of JI Seed compost covered with a layer of sharp sand. Some of the sand falls into the holes and helps keep the cutting well drained and stops it rotting.

    Attachment 53566

    I'll be looking to fill this half-tray up (another 12 cuttings) by the end of the month.

    In the meantime I've put them onto the heated propogator with the lid on. In this way I will "encourage quick rooting by means of a suitable compost, ample and constant moisture, and a little bottom heat" as advised by Mr Allerton.
