Ti are basically really really easy. The main thing that will get them is chemicals from water...so if you can, collect rainwater. Flouride is especially nasty to them. They also like a lot of fertilizer (I've learned this recently) and mulch.... Plants take on a certain flourish when foliar fed...
I grow Ti in 'stands' with color arrangements and I keep the heights varying for interest. When I cut back a stalk, I strip the leaves and use them for mulch on the remaining plants. Even in a pot you can use the old icky looking leaves for mulch.
Old leaves from any plant is the best mulch you can use...like a fertilizer!!!!
Hope this helps....
