How to grow blackberries from seed

Blackberries are native to North America especially the Pacific Northwest. The botanical name is Rubus Fruticosus and the common name is Blackberry. The plant is a perennial plant that grows best in USDA hardiness zones five through ten, and they are commonly propagated through cuttings or division. This method gives an exact copy of the berry bush. Blackberry shrubs can also be grow from seeds but the seedlings vary in features. Actually the best time to plant young blackberry seedlings outdoor is in September, though the germination process begins 6 months earlier.

Harvest the blackberry fruit and then use the fresh berries to gather the seeds, not dried fruit. The germination rate drops when the blackberry seeds dry out. You can place the fruit in a blender, pulsing on low until the seeds and fruit separate from each other. You have to strain the berries out of the juice and then pick the seeds out of the pulp with tweezers.

Examine each of the blackberry seeds for scratches or nicks. Scratch any seed without damage with a very good sharp knife. Scarification helps to break the strong blackberry seed dormancy surrounding the embryo.  

You have to place the blackberry seeds in a reseal able plastic bag along with a handful of damp peat moss. Then seal the bag very well and place it in a refrigerator with temperatures around thirty-three to thirty-five degrees Fahrenheit. Keep the blackberry seeds chilled for about twelve to sixteen weeks.

Fill the seed trays with seed starter soil and then spread the blackberry seeds on top of the soil. Lightly cover the blackberry seeds with soil and then place it in a warm area. Blackberry seed germination does not actually require bright light since the blackberry seeds are covered with soil. You can mist the soil with water in a spray bottle any time the soil begins to dry out. Immediately the seedlings begin to sprout, you can move the tray to an area with bright light.

Furthermore, remove the weeds from the planting area in full to partial sun. Make sure you pick a location with good drainage. You can spread about 3- to 6-inch-layer of well-rotted compost over the planting area. Dig the organic material into the soil with a shovel. Work the compost into the top eight inches of soil. This will really give the blackberry plants a good source of slow-release nutrients. You have to smooth the soil with a rake.

Dig the holes with a hand trowel only as deep and wide as the seedlings’ root balls. Space the holes out about four to six feet apart. Place the seedlings in the holes and then fill it with soil. Gently firm the soil around the brambles so that they can stand up. Space the rows about ten feet apart.

You have to water the soil around the base of the blackberry plants until the soil is slightly muddy. Give the blackberry plants one inch of water every week when there is no rainfall during the summer. Spread two to three inches of organic mulch around the base of the new shrubs. Actually mulching really benefits the blackberry bushes by reducing the weed growth, slowing the soil moisture evaporation and also providing slow-release nutrients to the plant. You have to keep the mulch layer thick throughout the life of the blackberry bushes.
