Time for another look at my tree lily propagation project.
What I find curious is that some of them have thrown up a single stalk as if they were about to flower like the parent plant, whilst the others have no main stem and are forming a rosette of leaves at ground level instead. Why this difference exists I have no idea, but when I came to pot them on, it seemed to be that it was the smaller bulbs producing the single stem and the larger bulbs producing the rosette:
Looking at the two side by side, I can’t help thinking the bulb with the rosette looks the stronger and healthier of the two and is better placed to grow on more effectively, but who knows? I’ve potted them on into larger pots of multi-purpose compost mixed with a little perlite for extra drainage and will label them so that I can keep an eye on them as they develop and note any differences in growth and habit next year. I’m fascinated to find out, I have to say!
As for the plant that was eaten by the slug, I was going to chuck it straight in the compost bin (I’m not exactly short of lilies!) but, of course, I had to see what was under the compost, and it turns out to be a perfectly healthy-looking little bulb with a decent root system:
…so, naturally, I’m keeping it! I’ve put it back in its pot in some new compost and will see how it fares.
So, here they all are, freshly potted on, including a pot (the largest one) that I left as a group having decided not to separate them from the parent scale to see if it made any difference to the speed of development:
One thing that did concern me as I was potting them on was how deep to bury them. When you plant dormant bulbs you are supposed to cover them with around twice their height in soil, but these of course are not dormant, so I presume that they should be covered more or less to the depth they were previously? That’s what I ended up doing, so I hope it’s right! I’ll keep them out of hot sun (assuming we get any!) for the next week or so whilst they re-establish, then grow them on in a nice light position until the end of the season when I shall have to decide how to over-winter them: coldframe? sheltered position in the open air? Not sure yet…and I’ll probably change my mind a dozen times knowing me! I expect I’ll hedge my bets and do both…:)
Time for a progress report on my lily propagation project, which started at the back end of last summer.
In February I posted a picture showing the new plantlets having sprouted a single leaf each:
They stayed like that for a few months, during which time I hardened them off to outside conditions. Then at the beginning of May I started to notice more growth, so I reckoned it would soon be time to investigate what was going on below the surface. I finally got around to doing this today, and here is what I found when I knocked them out of the pots:
Perfect little replicas of the parent bulb complete with tiny scales, measuring about the size of a 20p piece. Here is a slightly closer view:
They were still attached to the scales from which they grew, so I very carefully broke them off before I photographed them and then potted them up individually into 7cm pots of multipurpose compost.
I sincerely hope that my timings are right and that I’ve done what I’m supposed to do. It may be that you’re meant to leave the new mini bulbs attached to the parent scale until it rots away rather than breaking them off to fend for themselves, but I haven’t been able to find out one way or the other, so I’ve taken a chance!
I’ve put them back in my coldframe in the shade for the time being to give them a bit of protection, so we’ll see what happens next. Fingers crossed!
Finally got around to taking a photo today:
Coming along nicely!
The sprouted scales were potted up 3 months ago into 10cm (4in) pots of fairly fibrous multipurpose compost and placed by my north-facing patio doors to keep them as cool as possible in this centrally-heated house.
By early December I started to see the first grass-like shoots poking out of the compost, and now I would appear to have 10 new plants on their way – apparently, each scale is capable of producing more than one new plant, which is great if you really want to bulk up your stock.
I’m keeping them in the house for now, but it probably isn’t ideal – I suspect they’d be better off in a cool greenhouse, but I don’t have one of those, unfortunately! – and I’ll look to move them outside to my coldframe as soon as the weather is clement enough (hopefully in March sometime).
It will be at least a couple of years before they reach flowering size, but I know they’re gorgeous, so well worth the wait!
Inspired by this video http://www.youtube.com/watch?v=-b7Oz9PWca8 , I decided to have a go at propagating one of my tree lilies today.
The lily in question is this one, “Monet”:
My other two tree lilies (“Picasso” and “Cezanne”) have seen fit to reproduce of their own accord over the years, but this one never has, so I’m giving it a helping hand.
As per the video, here is what I did:
1. Sourced the bulb, which in this case meant carefully digging it out of its pot:
The plant finished flowering over a month ago and is heading for winter dormancy, so a bit of messing around with it won’t hurt it at this time of the year.
2. Cleaned off the soil from around the bulb and peeled off a handful of the outer scales:
They come off pretty easily, like separating cloves of garlic from a bulb. The lady in the video above says to take about 6 or 7, but I think I took a few more than that – 8 or 9, maybe:
3. Then I put them in a plastic bag of slightly damp compost (not too wet or I imagine they’ll rot), labelled them and placed them somewhere dark and warm (the airing cupboard).
I finished up by replanting the parent lily bulb, and hopefully the job was a good ‘un!
Now it’s just a question of waiting, checking the scales from time to time, and in a couple of months there should be signs of new plants growing at the base of them, which can then be potted up for growing on.
I’ve never tried this before, so I shall be ridiculously excited if it works – watch this space!…
