Blackberries - Key Growing Information
SCIENTIFIC NAME: Rubus spp.
CULTURE: Blackberries perform best in full sun, with good air movement and fertile, very well-drained soil. Raised beds are an option if your site is poorly drained. Blackberries prefer soil with a pH of 6.5–6.8.
PLANTING: Adequate spacing is important for best yields. Beds should be 3' wide, with paths between the beds a minimum of 8' wide. Space plants 36–48" apart in the row. Transplant plugs deeply enough to cover plug soil with ½-1" garden soil. Irrigate well after transplanting and maintain good moisture levels until plants are well-established or for 4-6 weeks after transplanting. Mulch to keep the soil evenly moist and to prevent weeds. Our technical sheet #8857, Blackberry Production, included with each order, provides more in-depth cultural and pruning information.
HARVEST: Primocane varieties will bear a small crop during their 1st year, with full yields beginning the 2nd year. Blackberries for fresh eating are almost always harvested by hand, as they do not ripen uniformly enough to machine harvest. Keep berries cool after harvest.
