Phalaenopsis aerial roots query

I have a Phalaenopsis +orchid which is now quite tall but leggy. It flowerd ok last year and I keep it as healthy as I can with watering and misting. My query is that it has now developed aerial roots not only at the base where I expected them to be but at the top which you can see in photo.

My question is:- a) Is this a sign that I should detach the stem just below the aerial roots and try propagating it by correct potting etc or b) should I just leave it as is or c) cut the shoot at it's base ?? Any advice will be greatly appreciated

 

I would bend it over and anchor the ariel roots onto another pot of bark, with a U of wire, beside the mother plant if you want to try propagating a new plant. If not, just cut the new plant off just below where the ariel roots are growing from and bin or give to a friend.

 

What you have is a keiki, Hawaiian for 'baby'.
You can just remove it from the old flower spike and pot it up.
