Algae on lawn grass: causes, misconceptions and simple fixes
Episode 38
Show notes
This episode explains what algae on turf is, how it differs from moss, and why it appears: persistent wetness from compaction or poor drainage, heavy shade, overwatering, excess thatch and scalping. It covers how algae forms slimy black crusts, reproduces by spores and fragments, and why treating only the algae without fixing the causes makes it return.
Practical solutions are discussed, including improving drainage (aeration, hollow tining, Liquid Gypsum), removing thatch, reducing shade, reseeding/scarifying, and cautious chemical options for professionals. The episode also highlights related organisms (liverworts, lichens, oomycetes) and notes algae can be a slippery hazard on sports turf.

Is Your Lawn Really Dead? Heatwave Truths & Recovery Tips
Episode 26
Show notes
In this episode of Grass Me Up the host explains how extreme early heatwaves affect lawns, why plants use so much water (mainly for gas exchange), and which grass species are most vulnerable.
He covers timelines for dormancy and death in different soils, common issues like fairy rings and fertiliser scorch, and why roots may keep growing even when the surface looks dead.
Practical tips include avoiding fertilising baked soil, using a wetting agent before heavy rain, applying seaweed extract after rain to speed recovery, and considering silica treatments to improve future heat resilience.

Biostimulants explained: boost your turf naturally
Episode 19
Show notes
Dr. Russell Sharp of Eutrema Ltd introduces biostimulants = substances that improve plant growth, root development, stress resistance and photosynthesis without acting as fertilizers or pesticides. He explains how they give turf an extra performance edge when nutrition and growing media are already optimal.
