Why did the sod edges dry out after installation? Will it recover?
More than likely your sod will recover from dry edges. Sod needs to be installed so the edges are butted close together. Gaps will cause edges to dry out. Try to push sod pieces together to avoid gapping. Sod edges can dry out while sitting on the delivery pallet if not installed promptly. Weather and wind can also contribute to drying edges. Conscientious watering, time and patience should result in the regrowth of the damaged area.
