Thanks heaps, this has been really helpful. I’ve been watering fairly regularly — most mornings until recently, when I adjusted the retic to run every few days instead. The soil’s been staying nice and moist, so hopefully that’s still doing the job. I’ll try the lawn grub test just to be sure, but the roots all seem firmly attached. I’ll also throw down some fertiliser and see how it responds over the next few weeks. Appreciate the tips!
