i wish can write about it like an expert, but i only tried doing cuttings a few times. I did it already with hj several years ago, which lived for about a couple years then croaked.
i am not really sure if it is better to have them leaf out first, then take a cutting and treat with IBA, or if it is better to do the cuttings in winter(prior to leafing out, and then treat them with IBA when weather gets warmer)
btw, i treated them with Hormex #16, or should i say–nuked them with Hormex #16, as have no clue as to what the optimum concentration really is needed for this hard-to-root species.
yes, yes, organic produce “purists” will probably ding me for using iba, but have to qualify that iba is virtually non-toxic and is actually a hormone produced naturally by certain plants. And even if it is not considered organic, the application is only a one-time thing, because propagating jujus on own roots is easier via root cuttings, so once you get a cultivar’s stem to root, you simply just poach for root cuttings when the self-rooted clone sizes up
anyway, the only “expertise” i can vouch for is that it is best to grow them in humid conditions…hence the makeshift greenhouse, aka uber-ghetto ziploc bags and to give them as much light(until the new growth shows signs of getting droopy…)
a few others have been cloning(or attempting to clone) jujus on own roots: @Livinginawe, @tonyOmahaz5, and just recently as myself, @k8tpayaso.
at any rate, will be posting a little video tutorial on self-rooted jujus as soon as i get my photos(and my life) organized…
