Remove sponge in center of mini phal?

I found a link to Yamamoto orchids pages on dendrobiums through the dendro forum here and they had some very solid info. I’ll have to wait another month before we’re past frost at night. The joys of living in Northern Ontario.
Thank you for your tips! I look forward to learning about a new plant species.
It’s done blooming now so it’s a crazy looking stick but it was lovely for a while.
