How to Grow a Red Wineberry From Cuttings

Rubus phoenicolasius, commonly known as Japanese wineberry, wine raspberry or red wineberry, belongs to the blackberry genus of the rose family. This edible berry originated in temperate climates in Asia; horticulturists brought it to the United States in 1890 to cross-breed it with raspberries and blackberries. At least six Eastern states list the wineberry as invasive; Connecticut and Massachusetts have banned it entirely. You shouldn't attempt to grow red wineberry in your yard unless you can contain it to effectively prevent its spread, according to the Plant Conservation Alliance.

Instructions

  1. Root Cutting

    • 1

      Dig down to expose a section of the root after the plant goes dormant in late fall or early winter.

    • 2

      Cut a 2- to 4-inch section of healthy root from the plant as close to the main stem as possible.

    • 3

      Bury the cutting in about 6 inches of moist potting mix, keeping the stem-side cut level with the top of the soil.

    • 4

      Keep the potting mix evenly moist and protect the cutting from direct sun. Move the container into full sun once it produces several new shoots. Water the pot to keep the mix fully moist but not waterlogged. Transplant the cutting when the new shoots reach several inches tall, either into a larger pot or into the ground. Feed it with liquid fertilizer according to the product directions.

    Stem Cuttings

    • 5

      Cut a 4- to 6-inch section of plant stem from just below a node where a leaf attaches during the early part of the growing season.

    • 6

      Remove about half of the leaves, starting from the bottom of the cut stem and leaving three leaf sets intact. Pull off any flowers, buds or berries.

    • 7

      Dip the cut end of the stem into liquid rooting hormone, if desired, according to the product directions.

    • 8

      Stand the cutting in a pot filled with 6 inches of rooting mix, patting it down to hold the cutting steady. Leave 1/2 to 2/3 of the cutting above the soil level. Water the pot evenly and thoroughly.

    • 9

      Set the pot in a plastic bag, using sticks to keep the bag away from the cutting. Tie the bag closed at the top. Place the pot in bright but indirect sunlight. Maintain constant dampness without allowing the rooting mix to become soggy.

    • 10

      Check for roots after a couple of weeks by gently lifting the cutting out of the pot. Once roots form, open the plastic bag and move it down slightly more each day, removing it entirely after about a week. Transplant the cutting to its permanent location. Feed it with liquid fertilizer according to the product directions.
