Zoysia Matrella and Winter Yellow Patches – Mystery Solved!

Recently my Zoysia lawn started developing unsightly yellow patches. This made me worry as it happened right at the beginning of the winter here in Brisbane and we’ve had a fair bit of rain as well. The immediate suspect was of course fungus!

Upon closer inspection of the entire lawn surface, I realised that each yellow area was accompanied by flowers and seeds.

It appears that it’s a fight for resources and the grass prioritises seed development while sacrificing chlorophyll production and leaf health. I wonder if this can be prevented by applying rapid greening liquid fertiliser in early stages of yellowing.
