Excellent Water Retention
Coir has better water retention qualities then peat and other growing media. This has obvious advantages in dry climates or at times when plants cannot be watered frequently such as in transit to market.

Quickly Reabsorbs Water From Dry State
Coir peat absorbs moisture immediately, even from a dry state, unlike sphagnum peat which tends to shrink when dry and form a crust. This causes water run-off from the top surface and water loss between the peat and the inside edge of the flower pot. Thus plants growing in coir tend to recover quicker from dry conditions.

Irrigation Efficiency
The ease of re-wetting and the quick drainage characteristics of coir means that coir needs to be irrigated less frequently and for shorter periods. This leads to reduced leaching losses of nutrients and lower water use.
