Firstly i admit i am clueless in plants so treat this 45 years old man like a kid when you explain stuff,

I get this last year she was getting bigger rapidly but was nice for the past 8 months. suddenly this middle big stem came from ground and started dying, yellow to brown leafs, i cut the first top part, then the lower leaves started turning brown and dead so my dad cut it like this.

I water it every two to three weeks with cup of human drinking water, or by touching the soil to see if its dry then i water it.
