Light: Full Sun
Soil: Prefer acidic to slightly basic (6.0-7.0), well-drained, organic soil. However, they adapt to most soil types except alkaline and wet. If you have clay soil, you will need to amend with organic matter. To increase the soil's organic content, amend with organic mulch-wet peat moss, well-aged sawdust, straw or leaf litter.
Pollination: Blackberries are self pollinating.
Hardiness Zone: 4-9
Minimum Chill Hours Needed: 400-500
Where to Plant: Blackberries tend to form thickets and are vigorously rooted. Locate the plants where you can control "volunteers. " Blackberries have long roots and send up suckers many feet from the parent plant. Leave room to mow around the beds.
Do Not Plant: In established garden areas where you have previously planted vegetables or fruit plants. Plant blackberries 300 feet away from raspberries.
Trellis Support Not Needed: 'Arapaho' blackberries do not need a trellis for support. However, they can be trained to a trellis no higher than 6'-8'.
