Hi everyone

I'm still in a wheelchair due to the ankle fracture and about to start physical therapy this week. But I'm gettin' there
I've been wheeling myself around the orchids to do what I can for them and I found this one Cattleya has four little buds.
My question is should I be worried about the 'sheaths' I've read so much about?
Are these buds in sheaths and should I cut them open? Or are they fine as they are? I just don't know
They are not dry,they are soft and velvety to the touch
Thanks so much for any advice you can give me.
Orchid hugs!
