Frequently asked questions

How do you pronounce coir?

It is usually said as KOY-uhr, rhyming roughly with 'lawyer' in many British accents. A single-syllable pronunciation like 'coy' is also heard in the horticultural trade.

What is the difference between coir and peat?

Peat is decomposed bog vegetation dug from wetlands, while coir is a by-product of coconut processing. Gardeners increasingly use coir because harvesting peat destroys carbon-rich bogs, though coir holds water differently and contains fewer nutrients.

What is coir used for?

Traditionally for rope, doormats, matting, brushes and mattress stuffing, because the fibre is stiff, salt-resistant and slow to rot. In modern gardening, the finer coco peat grade is used as a soil substitute in pots and hydroponics.
