Plant Magic Coco Coir is probably the only reliable alternative to market leaders Canna.
Plant Magic carry out no heat treatment of their coir to ensure all of the naturally occurring beneficial fungus Trichoderma remains. This encourages healthy root growth in your plants.
The coir also undergoes a special buffering and rinsing process to refine it and assist in the absorption of nutrients.
Although still fairly new to the market, early indications are that this coir is at least as good as its rivals and frequently better than most.
Plant Magic Coco Coir is formulated to work with the coco nutrients in the Plant Magic range, but should also perform well with any other coco feed.
