Coco peat or coco coir, by-products of the coconut industry, must be properly processed—aged, washed, rinsed, dried, buffered, ground, and graded—to be garden-ready. Without this, it may retain excess salts, compact over time, and cause nutrient imbalances, especially calcium and magnesium deficiencies. Due to its natural negative charge, coco peat can hold onto certain nutrients, leading to “nutrient lockout,” where vital elements like calcium aren’t available to plants. This is harmful, especially for sensitive high value plants that need optimal nutrition for higher yields. To prevent issues like fertilizer loss, salt burn, and poor plant health, using high-quality, buffered coco peat substrate is essential.
