Cuttings into pot what mix.

[davidwood]

I followed Charles advice and grew a cuttings in water. First of it had this sort of white stuff and now it seems to be growing roots[very thrilled about this,i have had my first graft and now maybe a cutting].
I need to ask at what point do i take it out the water and put it  in a pot and what do i use as my potting mix and at what %.
 I have river sand, clay, coco coir and worm castings,there is a sort of garden centre here in Nha Trang but that's all they sell.

David, the white tissue that forms on the end of the cutting is called callous. It is undifferentiated plant tissue that is usually thought to be necessary for root formation. However, by rooting a lot of hibiscus in clear glass containers I was able to watch the process closely. I was interested to find that sometimes roots grow without the callous forming and sometimes a large amount of callous forms but roots never do. The roots generally emerge from the edge or sides of where the wood was cut and not from within the main body of callous. Also it was fascinating to see the difference in the roots when rooting hormone was added to the water. That made me a believer in using it. Hibiscus will root without it but the number of roots emerging and the thickness and vigor of the roots was much greater when using the hormone also called an auxin.
The roots are very breakable at first so I don't recommend you take it out of the water until they are several inches long and seem well attached.

Good job!
