How to Harvest Seeds

Harvest the seeds when they are mature and have a whitish color, indicating maturity.

Next, you must mash the fruit, sieve the mixture, dry them, and finally winnow to separate the seed from the chaff.

If you cannot harvest seeds yourself, you can always order them online at Prairie Seed Shop in Canada.

Stratification

Western Snowberry seeds benefit from stratification. Place them in a plastic bag with a moistened substrate (e.g., peat moss) and refrigerate for 6 weeks.

Sowing

Sow the seeds in well-draining soil and keep them consistently moist until germination, which typically takes 2-4 weeks.

How to Propagate Western Snowberry (Symphoricarpos occidentalis) by Cuttings

To propagate Western Snowberry through stem cuttings, follow these steps:

• Timing: Choose a healthy parent plant, and take cuttings in late spring or early summer when the plant is actively growing.
• Cutting Selection: Select semi-hardwood cuttings with a length of 4-6 inches, ensuring they have at least two nodes.
• Preparation: Remove the lower leaves, leaving only a couple of leaves at the top. Optionally, apply a rooting hormone to enhance rooting.
• Planting: Insert the cuttings into a well-draining rooting medium, such as a mix of perlite and peat moss.
• Environment: Place the cuttings in a shaded area with indirect light. Keep the soil consistently moist but not waterlogged.
• Rooting Time: Roots should develop in about 4-6 weeks. You can gently tug on the cutting to check for resistance, indicating root formation.
• Transplanting: Once rooted, transplant the cuttings into individual pots with potting soil. Allow them to establish before transplanting into the garden.
