    Recently the undamaged tip of this plant developed a small "pimple" mid-way between aureoles. The next thing I knew, it had thrown a new pup, as pictured. It's a seed-grown TPM hybrid, so I guess eccentricities should be expected. It's unlike T. peruvianus "sausage" where new links emerge from an aureole (as far as I know).

    The nutrients in that mix might be counter-productive for the purposes of germination. I had a batch of A. phlebophylla seedlings that I killed (wilting, shrivelling, and dying pretty much as you describe) because I accidentally fertilised them. 

    Seeds in general, I reckon, are self-sufficient and have no need of additional nutrients. So I tend to avoid fertiliser at this stage, as a rule of thumb. 

    For potting on, once established, native potting mix from Bunnings gives good results. 

    Bunnings also sells coarse river sand for propagation, your best friend. 

     

    Here's what Simmons recommends (scanned pages with info here)

     

    Seed growing mix:

    3 parts washed or sterilised coarse river sand

    1 part peat moss or aged crushed pine bark

    or

    3 parts perlite

    1 part peat moss

     

    Potting on mix:

    3 parts coarse river sand

    1 part peat moss or old milled bark

    1 part loam or perlite

    or 

    2 parts sand

    1 part peat

    1 part gravel with old manure or compost added

     

    Cutting mixture:

    3 parts coarse river sand

    1 part peat moss or old crushed bark

    1 part perlite

    or a soil-less mix

    3 parts perlite

    1 part peat moss

    Google "Simmons" on this site for cultivation tips. Information from her book Growing Acacias. 

    Leggy suggests they're looking for more sunlight. 

    I don't know what "native soil mix" means, but it could be overcharged with nutrients. 

    I tend to avoid peat moss for acacias. I wouldn't even bother trying without coarse river sand. 

    I transplant them to tubes after they've germinated en masse, and developed true phyllodes. 

    Mine start off life in a greenhouse, so I doubt that your indoor humidity is the problem. They do need to be gradually acclimatised to less humid conditions.

    I have some acuminata (narrow phyllode) seedlings in grow tubes that are ready to go, if you get desperate.

    From a cut Opuntia (prickly pear) crystalline nodules sometimes appear around the central veins when healed, a bit like congealed sap. (If it oozes, it does so very slowly). I thought that might even have been the source of kefir "grains"? But I don't think there's much toxicity involved, as Opuntia is edible and even marketed as a superfood. Euphorbia sap, on the other hand, is said to be some nasty shit, avoid skin contact, etc.

    In recent years the WHO and FDA both determined that Kratom was not a drug of concern. So that's encouraging. 

    There have been copious studies on Kratom's (relative) safety since the TGA scheduled it as a poison in 2003. Not to mention, a synthetic opioid epidemic. 

    I think it's only one of two active alkaloids, mitragynine, that's included in the poisons schedule.

    How would the drug testing regime be enforced, i.e. what penalty? I can only imagine the scandal of a female MP being tested positive for alcohol - versus her male counterparts like Barnaby Joyce, whose approval rating is still being shored up by a protectionist mainstream media. I'm not sure what the parliamentary rulebook says about drunkenness or illicit drug-taking. But there'd be no point in testing if there weren't any consequences. 

    Furnishing Kirrabilly House with one of the world's best-stocked wine cellars probably doesn't help, or set a good example. On the PM's salary, he/she/it can afford to buy their own.

    strong resistance amongst whites and black towards using native South African plants.

    A "mere" 61 species documented in this study of S. African childhood diseases, of an estimated 30000 plants known to traditional healers. The authors point out that the cost of western medicine is prohibitively high, which has led to a resurgence of interest in traditional plant medicines. The study itself does not associate the use of traditional plant medicine with better or worse health outcomes (such as child mortality rates) in rural areas. But I think one of the study's implications is that, maybe not all of these traditional remedies are effective.
