Planting Guide - Raspberries & Blackberries
Spacing
- 18”-24” for reds and yellows; 20" - 24" for blacks
- Blackberries should be planted 3’ - 4’ apart
- Recommend 8’-12’ between rows depending on machinery
Irrigation
- Soak in water using Agri-gel™ for 1 - 2 hrs before planting
- Water thoroughly after planting
- 1" - 2" rainfall or equivalent per week
Fertilization
- Before planting add ½ - ¾ lb of 10-10-10 per 100 sq ft
- Commercial growers should use 500 lbs per acre
- An additional 1lb of 10-10-10 per 100 sq ft can be applied in July or August and in early spring in following years
- pH: 6.0-6.5
Weed Control
- Regular cultivation is necessary during growing season
- Roots are shallow–don’t cultivate more than an inch deep
- Mulching during establishments can help control weeds
- Contact a local extension for chemical recommendations
Trellis
We suggest plants are supported by a trellis
Trellising keeps canes upright and fruit off the ground.
A trellis makes picking easier, and maintains good aeration, thereby reducing disease control.
T-Bar Trellis 3’ above the ground supporting 2 wires 12 " apart
(Taller varieties such as Canby, Taylor and Lauren may benefit from a 2 wire trellis -
one at 3’ and another at 4’)
Blackberries and Black Raspberries are best trained to a 4 wire trellis
