Easy to grow AND productive!

  • Blackberries need at least 8 hours of full sun, and should be spaced 2-3ft apart.
  • Amend the soil* thoroughly before planting.  Mix in plenty of high-quality compost to existing soil, or create a raised bed by using quality garden soil.
  • High nitrogen fertilizer is best applied in two annual applications:
    • In spring, when the buds begin swelling.
    • In summer, after the fruit harvest is completed.

 *If soil pH is over 8.0, blackberries can exhibit interveinal chlorosis from iron deficiency, which is corrected with soil applications of iron supplements, or foliar feeding with seaweed with iron.

Blackberries are biennial plants having two types of canes.  1st year canes are called primocanes and 2nd year canes are called floricanes.  Floricanes are flower-bearing canes, which die after the fruit crop matures.

  • Every year after harvest, cut all old canes (the very ones you just stripped clean of berries) down to ground level.  Allow only the vigorous new growth to remain.
  • When these new canes reach 3–4 feet long, thin them so that only 5-7 canes per plant remain.  At the same time, prune back the canes to 4 feet long to encourage branching, on which the bramble will fruit next year.
  • Harvest when the fruit is dark black-purple, soft, and releases easily from the stem! At peak production, you may need to harvest daily. It may be helpful to use bird netting to protect your harvest.
  • Brambles may produce shoots from the roots.  These can be cut down to keep them under control, or with a sharp shovel cut out and transplant to propagate new plants.

Blackberries can become somewhat unruly.  To keep them neat and simplify harvesting, we can trellis the plants.  Consider using a one- or two-wire trellis (shown) to keep your brambles under control.  Place plants about 36in apart regardless of trellising.

Single-wire trellis: Place support wire 48in above the ground.
Double-wire trellis: Place support wires 26in apart and 60in above the ground.
