Title: Not so much cultivation as propagation - Origanum
Post by: Mark Griffiths on March 14, 2010, 02:57:06 PM: Hi, I have a couple of old Origanum dictamnus in the greenhouse..they are both looking a bit iffy, starvation? too wet? too dry? too cold? just felt unloved? I have no idea..so I want to take some cuttings if I can find some material.

I think maybe it's too early, but has anyone had any luck at this time of year? Though I've taken cuttings many times before I get the feeling it might be tricky this time. I was thinking sand, under the bench, no plastic hat.

If it makes new growth I'd have a go then rather than on old season's growth. But if it's on the way out it may be worth chopping it in 3 or 4 pieces and potting them separately.

I was trying to think when that would have been, it was probably 35 yrs ago..but I have a recollection of him showing me a Dionysia lammingtonii..so it would be about nowish I guess.

I know I propagated it that time round several times and because I currently have two, I know I did it several times within the last decade or so because I think I lost one a few years back we I moved here.

I'll let you know how I get on.

I got a 50% take which bearing in mind the quality of the tiny bits that were still alive is not bad.

So the cuttings were smaller and earlier than I would normally take, 1inch in March, dipped in rooting hormone, in sand with a plastic bag over the pot - plastic or clay gave me the same results.

I now have new growth and roots appearing out the drainage holes.

Post by: Lesley Cox on August 24, 2010, 10:59:37 PM: Well it sounds like a good result Mark, at least something retrieved and achieved. I don't know that my dictamnus has ever had anything that could have been layered, quite a compact tuft really, not like, say, 'Kent Beauty' which sends stolons everywhere - not that I mind. :D
