Blackberries are Loaded with Antioxidants & Offer Many More Health Benefits. They’re Full of Vitamins and Minerals like C, K, and Manganese, High in Fiber, and May Boost Brain Health. Cold Hardy to Zone 3, Blackberry is a Multi-Stemmed Shrub with Arching Canes that Often Form Large Colonies. The Canes are Armed with Stout Spines and the Inflorescence is Covered with Stalked Glands. This Blackberry Produces Edible Berries that are Eaten by Many Birds and Small Mammals.

While Blackberries can be Grown in Almost Any Soil, the Most Optimal Conditions are Loamy or Sandy Loam Soils that are High in Organic Matter with a PH of 5.5-7.0. While Blackberries are Drought Tolerant Once Established, for Optimal Fruit Production you will want to Water them on a Regular Basis.

Blackberry Germination:

1) Use a thermos to soak seeds in very warm water for 24hrs.

2) Cold stratify by placing seeds into a zip lock bag of moist peat moss or vermiculite, and place inside the fridge for 90 days. This will break the seeds dormancy and will allow them to germinate. Periodically check to make sure they do not dry out. Use a spray bottle to mist them so they're not overly wet as that can cause the small seeds to rot.

3) Plant seeds no more than 1/8" deep into a sterile seed starting mix. Keep "slightly moist" by misting with a spray bottle.

4) Use a heated propagator mat to keep the soil at 75 degrees F. during the day. Turn off the at night to drop the temperature to 68 degrees or less. This creates alternating temperatures which mimics their natural conditions in the wild which greatly improves germination rates.

5) Expect germination within 2-3 weeks.
