Past Tense of Shed
For the common verb senses, use shed → shed → shed, with present participle “shedding.” Do not transfer that rule blindly to Merriam-Webster’s separate verb sense “to put or house in a shed,” which is recorded with “shedded.” The noun “shed” meaning a small building is also separate.
For the ordinary verb “shed” meaning lose, cast off, give off, or cause to flow, the simple past and past participle are both “shed.” Merriam-Webster separately records “shedded” for the distinct rare verb meaning to put or house in a shed.

Quick tests
Verb-form test
Are you using the ordinary verb “shed” meaning lose, cast off, give off, or cause to flow?
If yes: Use “shed” for either simple past or past participle.
If no: If you mean the separate rare verb “to put or house in a shed,” do not apply the ordinary zero-change rule automatically; Merriam-Webster records “shedded.”
Caveat: Sense identification matters because the rare housing verb has a different recorded inflection.

Further guidance
Core difference
Use “shed” for the simple past and past participle in the ordinary verb senses.
Fast Test
First identify the sense. For ordinary meanings such as losing hair, removing layers, giving off light, or shedding tears, use “shed.” If the intended rare sense is literally putting or housing something in a shed, consult that separate “shedded” entry.
Usage Boundary
The zero-change rule applies to the common verb; the specialized housing-in-a-shed verb is a distinct lexical sense. The noun “shed” is not a verb-form use.
