I attempted making two plants from on seedling. I split a seedling and grafted on 21/09/08. One failed and the other got a successfull result.
I also did normal seedling grafting with 30 seedlings resently. All of them got a good result.
I will review the split seedling grafting method and will try again soon.
Split seedling grafting, sown seed on 24/08/09, grafted on 21/09/08, scion is caput-medusae.
