Propagating Sweet Olive (osmanthus fragrans)

Joeray(Z9 LA)October 10, 2007

Has anyone had any luck propagating sweet olive? I've tried repeatly with both in ground and air layering, without success. I know it's possible, because of the many plants for sale in nurseries, propagated by nurserymen. This plant is very reluctant to strike new roots, at least for me.

I use cuttings of this years growth taken August thru Sept. the cuttings are taken with a heel from a side branch. Then apply 0.8% IBA (rooting hormone) stick in well drained soil & mist .. Use bottom heat. takes 30-100 days to root.

I noticed georgez5il said to use bottom heat can you please explain what this means. I am currently trying to propagate osmanthus fragrans.

Thanks

set the container on a heating pad, or radiator etc. you are adding heat to the bottom of the container to increase the soil temp......(which is much more important than air temp)

Thanks for the info. I have never heard of that. I will have to give it a try.

I think the reason Osmanthus does not start as high a percentage as most cuttings is the tip cuttings are very thin with little reserve to start roots. Using a heel as george suggests will help but not as much as bottom heat. Al

Hi, new to all this, can someone tell me what a "heel" is?
Thanks

The wood to be used for a cutting is taken with part of the older branch from which it is growing attached. This attached piece is called the "heel". Al
