Harvesting Nets: Using nets placed beneath the shrub is more efficient for larger-scale collections. Gently shaking or tapping the branches encourages ripe berries to fall into the waiting nets, streamlining the collection process.
Seed Extraction
After successfully harvesting the berries, the next step involves separating the seeds from the surrounding pulp. This separation can be achieved by mashing the berries and then soaking them in water. The viable seeds will sink to the bottom, while the pulp and non-viable seeds can be readily skimmed off.
Drying and Storage
Once the separation process is complete, lay out the seeds on a flat surface to allow them to dry thoroughly. Subsequently, store the seeds in an excellent, dry location within airtight containers until you can employ them for restoration. When properly held, Serviceberry seeds can remain viable for several years.
Preparing Serviceberry Seeds for Restoration
Seed Scarification
Serviceberry seeds possess a hard outer seed coat that can impede germination. To enhance germination rates, it is advisable to scarify the seeds. This can be accomplished by gently scratching or nicking the seed coat with sandpaper or a file. This process facilitates water penetration into the seed, initiating the germination process.
Cold Stratification
Many native plant species, including Serviceberry, require a period of cold stratification to break dormancy naturally. This mimics the conditions they would experience in the wild, promoting successful germination. To achieve this, place the scarified seeds in a container with damp sand or peat moss and refrigerate them for several weeks before sowing.
