Upon doing some researches on Internet, I realized that this plant does not like too much water and only shaded sunlight. It can grow pretty well indoor. I removed a small portion of it and planted it in a terrarium. This is a open terrarium as I think Sedum Mexicanum grows better in dry condition. I have kept this terrarium in the bathroom dashboard for 2 weeks and it is doing well.
This plant is good in hanging basket type where the branches will drape down over the edges.
14 Oct 2014 - The plant in the open terrarium is showing sign of yellowing leaves. It is probably due to the lack of sunlight in the bathroom. I have moved the terrarium and placed it on the study table near the window. Hopefully, in a few weeks, I can see some improvements on the colour of the leaves. I have added some diluted fertilisers for houseplant. Just a little and will monitor the growth.
