Product Details

Unlike traditional blackberries that bear fruit only on 2-yr.-old canes, Prime Jan produces berries on new growth—a breakthrough for Northern growers who have trouble over-wintering blackberries. Fruit will form on 2-yr. canes as well, allowing for 2 crops in warmer areas. Erect canes grow 4-6 ft.; sweet berries ripen in June and July. Zones 4-8. Bareroot. PP15788.

  • Zones: 4 - 8
  • Height: 4-6 feet.
  • Spacing: 3 feet.
  • Depth: Same depth as they were in the nursery.
  • Spread: 4 - 5 feet.
  • Sun/Shade: Full sun.
  • Soil Preference: Well drained, rich, moist soil, 5.5- 6.8 pH.
  • Pruning: With upright blackberries, the key to success is correctly managing the primocanes to produce the "hedge­row" growth habit. Cane management includes pruning both during the growing season and during dormancy. I think of summer pruning as training because it consists largely of trimming the primocanes to control their shape. Training is a simple process that doesn't take long, but if you don't do it, your plants will grow leggy and possibly won't stand upright.
  • Pollinator: Self-pollinating.
  • Yield: 4 - 6 quarts, comparable to Apache & Ouachita.
  • Foliage: Deep green foliage.
  • Blooms: May.
  • Flowers: White.
  • Fruit: Floricane fruit averages 5 grams, primocane fruit varies from 2 - 15 grams, fruit typically 1" - 2" long.
