What does dehiscing mean?
"Dehiscing" is the present participle of the verb "dehisce," which means to split or burst open along a natural line of weakness. Its primary home is botany, where it describes seed pods, capsules, and anthers opening at maturity to release pollen or seeds — for example, a ripe follicle dehiscing along a single seam. The word also appears in medicine, where a surgical wound is said to be dehiscing if it separates or reopens along the suture line, a serious post-operative complication. Derived from Latin "dehiscere" ("to gape open"), it shares a root with "hiatus." Because of its technical character, "dehiscing" is rare outside scientific writing, but within botany and surgery it is the standard, precise term, valued for capturing a specific, natural mode of opening rather than any generic breaking apart.
Present participle of dehisce: to split or burst open along a natural line, as seed pods, anthers, or fruits do when they release their contents.
"The pods were dehiscing in the afternoon heat, popping audibly as they flung their seeds outward."
Almost entirely restricted to botanical and technical writing.
(Of a surgical wound) to separate or reopen along the suture line.
"The abdominal wound began dehiscing on the fourth day after surgery."
In clinical use, the noun "dehiscence" is often preferred.
Botanists have a single precise verb for the moment a pod bursts open and flings its seeds — and it comes from the same Latin root that gives us 'hiatus,' a gap.

Etymology of dehiscing
"Dehiscing" derives from Latin "dehiscere," meaning "to gape or split open," formed from the prefix "de-" plus "hiscere," an inchoative form of "hiare," "to gape." It entered English in the mid-seventeenth century, first in learned botanical usage. The same Latin root yields "hiatus" in English, and the adjective "dehiscent" and noun "dehiscence" are direct derivatives of the verb.

Strictly technical register: common in botany and plant science, and in medical contexts for wound separation. Rare in general conversation, where simpler phrases like 'bursting open' are preferred.

Decaying means rotting or decomposing, whereas dehiscing specifically means splitting open along a natural line to release contents.
