Propagation of Rubus adolfi-friedericii Engl. var. rubristylus Gust.
Rubus adolfi-friedericii Engl. var. rubristylus Gust. can be propagated by two primary methods: seed propagation and vegetative propagation.
Seed Propagation
Seeds can take anywhere from one to three years to germinate, so patience is necessary. Collect seeds from ripe fruit in the fall, clean them, and store them in a cool, dry place. In the spring, sow the seeds in a light soil mix, cover them with a thin layer of sand, and keep moist, but not waterlogged. Once the seedlings have emerged, it's important to grow them on until they're big enough to handle. It's possible to transplant the small Rubus adolfi-friedericii Engl. var. rubristylus Gust. saplings the following spring, individually into pots or in a propagating tray.
Vegetative Propagation
Vegetative propagation methods of Rubus adolfi-friedericii Engl. var. rubristylus Gust. include division, cuttings, and layering:
- Division: Cut clumps of Rubus adolfi-friedericii Engl. var. rubristylus Gust. into sections with a sharp knife in early spring. Make sure each section has roots and stems, and pot them up.
- Cuttings: Propagation by cuttings is straightforward. Take semi-ripe cuttings two to three inches long from new growth in summer or early fall. Remove the lower leaves and then insert the cuttings around the edge of a container filled with a rooting medium. Keep the cuttings humid under a polyethylene clear plastic cover, making sure it doesn't touch the leaves.
- Layering: Propagate Rubus adolfi-friedericii Engl. var. rubristylus Gust. by layering stems in early to mid-spring. The stems that are low to the ground will work the best. Bury the stem deep enough to create an arch, making sure the tip is above the soil surface. Secure the stem to the soil surface. Roots will form from the buried node, and once well-rooted, cut it from the parent plant and move it to its new planting location.
