Hello Tim, thanks for your comment. Honestly, I don't know how old are they? I bought them last year and they grow quite well inside house (outdoor in our place is too cold and get frost/hail). But their cans is between 30-35cm and 3.5cm round (quite fat can). I do fertilise once a week all year round except during winter as I read on the internet and it said we need to reduce water during winter to induce their spikes.
I've 1 big Dendrobium kingianum plant which had over 35-40 spikes last spring...
And this is Dend.Golden Arch:
Forget its name but it had very nice color and fragant flowers..
Cheers,
Long
