Yes, the inner 'core' does shrink in, creating kind of a concave cut surface. But the roots grow from the outer part rather than the core.

I'd root it now, provided you have a bright, warm place for it.

yes- the shrinking is normal. Plant on Wednesday. dip in B-1 and water and then into rooting compound and see the pics and the last two posts (15/16) on the post titles "Newbie, how do you root......." Bill

Thank you both for the information. I can do all of the suggested details and also can then place on a heated propogater base in a warm environment. I do hope it is successful I will let you know. Thank you also Bill for the link.

Hazel,
You've got a good one to try rooting. I can't remember a Celadine cutting that didn't root for me. Celadine's appear to tolerate almost anything. My first plumeria was a celadine that I put in heavy soil. It grew, not fast, but it survived. When I got it into good soil, it just exploded in growth. As always, be patient.
Mike

Thanks Mike for your encouragement. I do hope I don't fail but I will try my best for it and will be so pleased if I can report a success.I can't say patience is a virtue of mine but I can learn!
Hazel.

How often do you water a new cutting???

Hello Chena, I have just followed the instructions I was given, planted the cutting and given it a drink. I understand unless it shrivels significantly that's it until it hopefully roots but the experienced growers will tell you better than I can-I need all the help I can get.
Hazel.
