Tropicals & Tender Perennials: Trimming Hoya vines (and bloom spurs?), 0 by podster

This weekend I trimmed dead vines from my two large H. carnosa plants. These have bloomed heavily and are now putting on new growth. I found quite a few vines that have few leaves left. The leaves look dessicated and there is always a peduncle on them. From past experience, I know this vine will die too.

Photo shows how dry the leaves are and an older peduncle to the upper right. The plants seem to be thriving however.

My question is... can this be prevented? I hate to "waste" the bloom spurs.
