What It Is

Overview

This acidic, open coco substrate suits cane and bush berries.

Blueberries want an acidic root zone. Between pH 4.5 and 5.5 they take up iron and other nutrients properly, and outside it they show deficiencies such as iron chlorosis. Their roots are shallow and prone to rot, so the substrate must drain well and still hold steady moisture.

This blend uses 70% fine cocopith (0.5–5 mm) and 30% coarse coco chips (12–18 mm). Each 29 × 29 × 33 cm block weighs 2.7 kg, holds 27 L and has two plant holes. The same blend also suits raspberries and blackberries, and comes as a block or as square and round growbags.

Who It Is ForGrowers of blueberries, raspberries and blackberries in pots and bags who need an acidic, well-drained root zone.
