RE: potting mix for juno, scorpio

 

Hi all, 

Alice, using the Deno method, your seeds will be wrapped in damp paper towels and you won't have pots in the fridge - everyone wins! Plus you will use far less GA3 and the seeds will be exposed to it for longer. His paper on germination is available online; just google "deno seed germination". 

Pat, thanks for your encouragement. Perhaps I should put more of my Iris in the ground - I must admit I'm apprehensive about doing that with special plants! 

Mark, it's not that dry here. Not as dry as most of Australia... We're on the edge of a "rain shadow", so get much less rainfall than Melbourne itself, or the nearby ranges. It's certainly not arid here though, and the last few summers have delivered quite a bit of rain. It hasn't got that cold the last couple of winters either, certainly not to freezing anymore - I'm sometimes not sure if I should see this as a good or bad thing.  

cheers, Kyrill

Hello Kyrill, I'll get some GA3, and try it, 100% sounds encouraging, so if I follow bobs advice and grow them in large pots I'll have no room for food in the fridge , can you prick them out after germination? What pots do you use?Istill have some seeds coming so plenty of time to think about it all, thanks alice

Hi Alice, 

I'm new to the group too - another Aussie from the foothills east of Melbourne. Last year I started a few Juno species from seed and have some Arils to try this year. My advice is from this limited experience. 
Advice re mix from Marcus is sure to be accurate, as he is clearly an excellent grower. An open mix is vital. Regarding germination, all Junos I tried germinate either in the fridge or shortly after, following removal to warmer conditions. At least 3 months (and 4 won't hurt) cold stratification was needed; I didn't remove any seed batch from the fridge until at least 1 had sprouted. GA3 (gibberellic acid) is very helpful for most, and resulted in 100% percent germination for some species. I used it at 1000ppm, applied as recommended in Deno's paper on seed germination (available online if you don't have it). 
My research indicates that Aril seed will need similar treatment to Juno, and I will certainly ! be trying the same method this year. Hope that helps, good luck with your seeds. 

cheers,
Kyrill Harding

hi mark, no, I'm not in tasmania, but the conditions are similar to parts of, I'm in southern New South Wales, between the "snowy mountains" and the coast, in the hinterland, on the top of a decomposing granite hill (altitude 250 m.) temp 45 to -1 or 2 degrees celsius in winter, lovely sun most of the time, even when looking at the snow in the distance, it's meant to snow here every 7 years haven't seen it yet, maybe this winter. At the moment I'm expecting floods down in the valley some time in the next month, everything is totally saturated, and next summer we'll all be trying to dodge fires from hell (even the oxygen in the air burns now with the bigger fires), with all the re-growth from these last two seasons, but I'm going off in a tangent, whatabout potting mixes and culture? thanks alice
