indigo264nm Posted August 2, 2010 Any update of progress in growth and development of cuttings?? One of the things I'm curious about is whether there would be much or any advantage to propagation via cuttings. The fact that it's a bit of a challenge propagating most acacias vegetatively (and natives in general), and the fact that they by adaptation shoot out a really long and deep tap root upon germination to ensure stablility and access to water\nutrients in shit soil, makes me wonder whether it's worthwhile.

ferret Posted September 17, 2010 What time of year did you take successful cuttings? Could prolly figure it from post dates but it would be handy to have a range stated for easy reference. What type of material were the successful cuttings take from? Soft, semi-hard or hard? Looks like a semi-hard cutting in the pic. first successful cutting was taken in late spring, second was in late summer. semi-hardwood. Any update of progress in growth and development of cuttings??

San Rainbow Posted October 2, 2010 Nice work mate! Is the PDF you were talking about in earlier post a tek on growing Acacia from cuttings? Share this post Link to post Share on other sites
ferret Posted October 2, 2010 no i don't think they used any acacia's in their experiment, i don't have to pdf anymore since my portable hard drive shat itself but they found the technique produced roots faster and more reliably with a range of species, from memory they used some myrtaceae and rutaceae species, amongst others..

Magicdirt Posted October 2, 2010 So what's the theory behind diluting the hormone with acetone ? Is it for greater penetration of the hormone or just to adjust the concentration of hormones ? Share this post Link to post Share on other sites
Sola Posted October 20, 2010 I would describe my chemistry background as basic stopped studying chem at uni before I realised how useful it could be Access to the journal article should be no worries but where to get the chemicals to actually try this myself is another question The prospect of being able to take cuttings of my fav Acacia's is just too good, where might I acquire such chemicals and does doing so attract attention? Peace Share this post Link to post Share on other sites
ferret Posted October 20, 2010 yeah, i think the solvent probably allows greater uptake of the hormone. getting the IBA is no problem at all, google supergrow, a dude in canada. if you can i reckon using bottom heat will speed things along. thankfully i have got the full pdf of the article again, so give me a holla if anyone wants me to email you a copy.

IceCube Posted October 20, 2010 Just used the powder from bunnings to do some phleb, now wishing I read over this thread. If you want IBA: http://www.austratec.com.au/pdf-downloads/AUSTRATEC_PRICE_LIST_May_2010.pdf Share this post Link to post Share on other sites

ferret Posted October 21, 2010 Just used the powder from bunnings to do some phleb, now wishing I read over this thread. yeah man ive been bitterly disappointed by every powder i try. if i was you i would go and grab some rootex-G , its a gel, mix 2 parts gel to 1 part acetone and re-treat those cuttings. could also try the rootex liquid, straight at 4g/L, from memopry it smells like its got some kind of solvent in there..

Sola Posted October 21, 2010 (edited) Just acquired all the chemicals to give this a go, all I need now is for my Acacia's to get big enough to allow me to take cuttings. Are there any places in SA where these Acacia's have naturalised? I'm itching to give it a go. Might even practice on some non-ethno's I already have here. I'll post photo's if successful. Photos are of my only surviving obtusifolia. Edited October 21, 2010 by Sola Share this post Link to post Share on other sites
ENtiTY Posted November 12, 2010 Put about 40 cuttings down this morning ranging from semi-hard to soft, 3 to 6 nodes. There in a dedicated propagation room with automated humidity, temperature and bottom heat control. Just gotta keep the fungus gnats out now . Share this post Link to post Share on other sites
ferret Posted January 7, 2011 how they lookin Harry? here's my original cutting now, not really the most amazing growth over a year but she's still kickin at least Share this post Link to post Share on other sites
tripsis Posted January 7, 2011 Nice job man, it's looking pretty healthy and happy from here. Are the others around it seed grown? Share this post Link to post Share on other sites
ferret Posted January 7, 2011 its pretty much an established little plant now! yep the others are from seed, - mt jackson narrow acuminata and south coast obtusi. i have one other obtusi cutting that has grown a single phyllode since winter.. Share this post Link to post Share on other sites
ENtiTY Posted January 7, 2011 Just took pics this morn to post Out of all the cuttings I took only 1 has thrown roots and another 7 are calusing. Heated benches stopped working about a week in and fungus gnats have taken hold so I lost a few to them. Might have had a bit to much acetone in the hormone gel as all the dipped ends have died back about 3mm and those that have a calused have done so above the dead bit. Pics! Image uploading has changed? Have to do for now Share this post Link to post Share on other sites
tripsis Posted January 7, 2011 What type and strength hormone/s did you use Harry? Share this post Link to post Share on other sites
ENtiTY Posted January 7, 2011 Clonex purple gel, IBA 4g/L. Approx 3/2 gel to acetone. That was the aim anyway, was more like 1/1 lol. Share this post Link to post Share on other sites
tripsis Posted January 7, 2011 It comes in 4g/L? interesting. I've got 3g/L and 8g/L here. What was the acetone used for? Share this post Link to post Share on other sites
ferret Posted January 7, 2011 ahey! nice work man. now we just gotta work on the strike rate.. Share this post Link to post Share on other sites
ENtiTY Posted January 7, 2011 (edited) Wow 8g/L! Strong stuff Re the acetone see post 31 & 33 of this thread trip comes down to material and time of year I think. To many contributing factors with my attempt to narrow the field any, especially the fungus gnats and the heated benches breaking down. Three node semi-hard cuttings seemed to hold on the best under the conditions I have my cuttings. Will give this another crack Edited January 7, 2011 by Harry Share this post Link to post Share on other sites
tripsis Posted January 7, 2011 I'll have to read that article again. The 8g/L is powder, not gel. Supposed to be for hardwood cuttings. Will give it and the gel a go on some obtusifolia and sassafras cuttings when I'm back from NZ. Share this post Link to post Share on other sites
ferret Posted January 10, 2011 i wonder if the use of a fungicide and/or a non-organic planting medium would help with the die-back of the base of the cutting,? Share this post Link to post Share on other sites
