== Propagation ==

Salal can be raised from seed or cuttings. A University of Washington propagation protocol extracts seed by mashing ripe fruit and using flotation, then surface-sows it in a 1:1 peat-perlite medium. That protocol records germination in about 3–5 weeks, late-summer 15 cm cuttings, and rooting in about 4–7 weeks; it also warns that seedlings are slow to establish and that roots are sensitive during handling.<sup>[[#cite_note-4|[4]]]</sup> Keep the medium moist but aerated and transplant established stock carefully rather than disturbing the root ball repeatedly.

The protocol's timing and medium are a practical nursery method, not a guarantee for every seed lot. In a public r/pnwgardening discussion, u/ReZeroForDays described raising several seedlings from fresh fruit without stratification, while u/stuckinflorida described winter-stratifying seed outdoors in milk jugs and obtaining fairly good germination. The differing outcomes are consistent with the protocol's warning that seed condition matters; they are individual observations rather than a universal treatment.<sup id="cite_ref-6">[[#cite_note-6|[6]]]</sup>

Vegetative propagation is useful when a productive, fruiting plant is available, especially because the Orkney study identifies selection and vegetative multiplication as possible routes toward more uniform harvests. That study did not establish a named cultivar or a universal cutting method.<sup>[[#cite_note-5|[5]]]</sup>
