Firstly this is my first post. Let me know if you need any other details that I missed to provide.
My lawn (Sir Walter Buffalo) is now 7 weeks old (instant lawn). From last few weeks I am noticing that the gaps between the turf slabs is increasing and the grass is turning brown on the edges. I am watering regularly (2 times a week, @25mins each time) and in between with some occasional rainfall ( I live in Melbourne Suburb).
Three weeks back I started aerating using Trojan All Steel Spiked Aerator. And one week back I applied the fertilizer Seasol 2 x 2L Ready To Use Lawn Fertiliser.
In the pics it is not showing the exact gaps. The gaps are a bit wider than in the images. Can any of you please let me know how can I fix these gaps.
Thank you,
Sai.


There are other spots which much wider gaps
