i

 

Hi Diviy
No, it is a shrub, Aucuba Japonica and cannot be divided as it grows from a central stem. It can be increased by cuttings and maybe layering (if the stems are long enough and near the ground), but I have not tried this method.
As for the other plants, the soil may be different even 25 feet away and light conditions too. A nitrogen feed might help the yellowing one as it seems to be suffering from chlorosis.

 

advice on how to take a cutting please
ta in advance
i am that much of a newbie
