How to Grow Berry Vines From Berry Seeds

Remove a handful of berries from an existing vine in autumn or early winter. Use pruning shears to cut them off.

Place a clean kitchen towel or paper towel on a counter or table. Squish the berry against the towel. If your berry has skin, pull it away to expose the seeds. You can then squeeze the berry to release the seeds from its inside. Berries without skin will give their seeds away when squeezed.

Spread the seeds out on the towel and attempt to remove any flesh or pulp that is stuck on them. Run the seeds under water to remove any stubborn material.

Pour a gritty loam soil into a small pot with holes in the bottom. You could also use an 8-oz. foam cup with pencil-sized holes placed in the bottom. Fill the pot or cup to the top with the soil.

Sprinkle the seeds on top of the soil. Push them gently into the soil with your fingers. Only press them in enough to stick to the soil; don't push them down underneath. Place a thin layer of compost over the seeds and pour water into the vessel until it drains out of the holes. Sit the pot in a cold frame or sheltered area outdoors. Water the soil when it appears dry.

Transplant the seedlings into another pot when they develop two or three sets of true leaves. True leaves are the leaves that form after the first set occurs. Dig a hole that is just slightly bigger than the vine's roots. Place the vine inside the hole and cover its roots with soil. Transfer into a permanent home the following spring. Most vines prefer sun and rich soil; however, plant your vine according to what your particular berry prefers.
