Blackberries - Key Growing Information

A panicle of fresh, plump blackberries, produced on thornless 'primocanes.'

SCIENTIFIC NAME:

Rubus spp.

CULTURE:

Choose a spot in full sun with good airflow and rich soil that drains very freely; on wet sites, plant in raised beds. Aim for a soil pH of 6.5–6.8.

PLANTING:

Generous spacing pays off in yield. Make beds 3' wide with paths of at least 8' between them, and set plants 36–48" apart in the row. Plant plugs deep enough that their root ball is covered by ½–1" of garden soil. Water thoroughly after planting and keep the soil moist until plants are established, or for 4–6 weeks. A mulch keeps moisture even and holds back weeds. Our guide Blackberry Productioncovers growing and pruning in more detail.

HARVEST:

Primocane varieties give a light crop in their first year and full yields from the second year on. Berries for fresh eating are nearly always hand-picked, since they ripen too unevenly for machine harvest. Keep picked berries cool.
