The blackberries are planted one per meter around the outside perimeter of the farm. There is a 10m space left for a front gate so there is 390 meters and 390 plants. Blackberries need support and are traditionally staked on a row with a 2.5 cedar post (dug .66 in the ground). The cedar posts are 10 meters apart. Then 3 rows of 12 gauge wire is string between the poles. In our farm cedar posts are replaced by cement posts, also, the berries are fertigated. 390 plants are expected to use 390 liters a day in water. That requires 2 200 liter water containers and 2 200 meter driplines - holes one meter apart.
In soil, blackberries are expected to produce from 7 to 9 kilograms per plant in the third year, and then live for 20 years. In fertigation we hope to extend the growing season and obtain more fruit. But using the 7 kilo amount we expect the fence to produce (from spreadsheet). Blackberry Fence Calculations Labor to establish the blackberry fence 81 hours
