Frequently asked questions

What conditions cause algae to develop on putting greens and high-traffic turf surfaces?

Algae colonise areas where the turf canopy has thinned due to wear, compaction, poor drainage, or excessive shade. Warm, humid conditions combined with chronic surface moisture create the ideal environment. Low-lying areas on greens where water pools, particularly around collar dams or where irrigation overspray occurs, are the most common sites for algae establishment.

Why does algae prevent turf recovery even after the initial cause is addressed?

Once established, blue-green algae form a dense, rubbery mat on the thatch surface that becomes hydrophobic when dry. This crust sheds water, blocks light penetration to the crown, and physically prevents stolon and tiller growth. Until the mat is mechanically disrupted through spiking, verticutting, or light aerification combined with topdressing, the turf beneath cannot recover regardless of improved growing conditions.

What is the most effective approach to algae management on maintained turf?

Prevention through improved drainage, reduced irrigation frequency, and maintaining turf density is far more effective than curative treatment. Where infestations are established, an integrated approach combining chemical treatment with physical disruption of the algal mat is required.
