The Spiny-headed mat rush and its cultivars grow well in partial shade to sunny locations on many types of soils and with regular summer water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; summer water helps sustain its foliage character particularly when planted in sunny exposures.
