Hi all!! Ok, my problem is that on my Trichovanda Thai Velvet 'Meechai', each time the spike gets a certain length, boom it dies! By the look of it, I belive it has done this with ALL of its spikes, it just doesnt look like a spike was ever cut off. So I thought it has something to do with me, but my mother also has one (bought at same place, same time). Are we both doing something wrong, or is there something worng with this plant? Please help!

Thanks!
Tracy
