Hi peeps,

Recently am having this desperate issue on my "Japanese" Grass which planted by landscaper 3 months ago, it started off nicely but recently been noticed my "Density" of the grass has been reducing as per pic below.



Closer look reveal that there is this area with slimy substance that somehow block the growth and density of the grass?



Have actually did the below but problem still persist and getting more spot with this slimy buildup:

1) 2 weekly fertile exercise using urea N7 (white tiny ball) add in 2 tea spoon dilute with 5 L water.
2) 2-3 weekly pesticide exercise with Matadon 57 (spelling?)
3) Watering twice daily (Morning before work and night time after work)

Suspect of Slimy Buildup:
1) Neighborhood Cat that drop by during midnight or afternoon? Cat Pee?
2) Excessive fertiliser/ Pesticide activity?
3) There will be 5-6 birds that will drop by daily just to pick up those worms and alot of bird poo along the fences and lawn.
4) Excessive watering? I dint flood the lawn and no water retention issue as well.

Appreciate if anyone can shred some light on this issue.
