There are a number of retail products on the market that allow you to attach to your garden hose and spray-fill areas of lawn that have been damaged. These products all contain their own seed mixture which I would rather not use. I have my own high-grade grass mix that is suited for my climate that I would like to add to something so I can get it to stick on some areas that are sandy and wind-exposed.
What products (either DIY or retail) are out there that allow me to cheaply hydroseed/patch areas of a lawn with my own grass seed mixture?
