I just install KBG in my backyard 9 days ago. Now many of the seams are turning brownish yellow. The center areas of the strips are growing well but the sod isn't taking root yet. Any advice? Am I panicking too early? Background: Prep work was tilling and lime (ph is only 5.2). The sod farm told me it was pre-fertilized and I should not use a starter. We laid the sod immediately after delivery and it rained the following 5 days. Since then I've been watering roughly 1 hour in the morning (standard impulse sprinklers). The sod farm told me to mow at 10 days but I'm worried about doing that without the sod roots taking.
