I got a call from a HOA president the other day. In the subdivision, They have one pond out of 6 that is getting major washouts on the banks. They wanted me to spread the dirt on the banks enough to stop the eroding and plant some grass. I'm going to subcontract the work to a guy with a dozer. What would be the best to put down after everything is even. Should I put down sod or get it hydroseeded?
