Description
Stark® Blackberry and Bramble Fertilizer is formulated specifically for blackberries, raspberries, and other bramble fruits — plants that have a different nutritional profile than most fruiting crops because they put on substantial new cane growth every season alongside their fruit production. The 12-10-10 formula leads with nitrogen to support that vigorous cane development while providing the phosphorus and potassium brambles need for root health, fruit quality, and overall plant vigor. Apply twice per year: once in spring when new growth starts, and again just after harvest when the plant is developing the canes that will carry next year’s crop. A Stark Bro’s exclusive.

12-10-10 — Formulated for Cane Growth and Fruit Production
Brambles are unusual among fruiting plants because they produce an entirely new set of fruiting canes each year. Those canes need nitrogen to develop the length, diameter, and health that supports a productive fruiting season. Too little nitrogen and the canes are weak and thin; too much and the plant pushes vegetative growth at the expense of fruit. The 12-10-10 ratio provides the nitrogen leadership that bramble cane growth requires, balanced with phosphorus for root development and fruit set and potassium for plant vigor and fruit quality.
Two Applications Per Year — Spring and Post-Harvest
The two-application timing reflects the bramble’s annual growth cycle. The spring application, timed when new growth begins, feeds the rapid cane elongation and early season development that sets up the summer fruit crop. The post-harvest application is equally important and often overlooked: immediately after fruiting, the plant begins developing the primocanes that will carry the following season’s crop. Feeding those developing canes with available nutrients in late summer gives them the resources they need to harden off properly before winter and emerge strong and productive in spring.
