hi,
if you are getting some through the post don't be alarmed by its tattered state as it does not in any way travel well. plant what is left and leave it to recover.
i have mine in eco complete under what i would call medium lowish light and it does well. I use EI ferts, it goes a touch yellow and looses lower leaves when you dont do enough trace.
For expanding what you have when it is going well just uproot the plant and seperate the plantlets into groupings. it is obvious when the plant in growing well where you should seperate, it does it for you really. Then replant.
I have found that each time i expand the area of the plant by splitting and replanting there is a bit of die off from below due to the fragile nature of the leaves.
My current fav plant.
Best Regards,
John
