Rootzone Layer

The final layer is the rootzone layer, which is about 10-12 inches of a mixture consisting of 90% sand and 10% peat. This is the stuff the grass will actually grow in. For this I ordered 20 yards of USGA spec rootzone material from Luck Stone Specialty Products. This was delivered in a monstrous dump truck.
Now it was time to get the rakes and start spreading this stuff out. Stakes were set out around the perimeter and around the green to ensure the rootzone mix was spread out at a consistent depth. Once all evened out, the rootzone was rolled multiple times and re-graded to even everything out.

Next, starter fertilizer was mixed in the top 1-2 inches of rootzone. Finally, 1.2 lbs of Declaration bentgrass seed was spread out and rolled a final time for seed to soil contact.

Over the next couple of weeks, the green was watered on intervals of 4 times a day for 15 minutes at a time. This did of course change with rain and cooler temperatures meaning less watering.
