Hello all
I am led to believe that the Gahnia spp (native saw sedges) are very difficult to germinate. wondering whether you folk may have had experience with these
and have a few suggestions.
any help greatly appreciated

| Hi Cherax, the following comes from my favourite book by Murray Ralph 'Growing Australian native Plants From Seed'. A few species will germinate readily- G melanocrpa, G trifida. Some have an after ripening period and will germinate after 12 months dry storage - G grandis, G sieberiana. Most others germinate spasmodically, set little viable seed or are difficult to grow from seed - G decomposita, G radula. Try smoke treatment on all species as some do respond. Division and transplants have limited success. (I think it likely that a large number of seeds need to be tried to achieve germination of a few plants. Smoke treatment is worth trying with many difficult to germinate species, although some are not responsive.) |

Thanks for that Mallee.
I have 2 spp growing in my yard and I have tried smoke treatment and soaking. I have heard that they are difficult to germinate.
In this instance I will have to be patient.
Not one of my traits

| Hi there A I have tried to grow these plants too, from seed, without any success. Perhaps you could try the hot water treatment, this is done with wattle seeds to get them going. Someone also told me to soak seeds in dishwashing liquid, as this might break down the seed coat a bit, as well. Maybe I should listen to my own advice ! Popi |

| I've only grown sieberiana. I got a reasonable success rate cleaning with detergent to get rid of the sticky coating then soaking overnight in smoked water. |
