I had a woman call me today. The freshly built house had a yard that consisted mosly of red clay and rocks, with very little grass sprinkled in. She said the house across the street had the same yard, but hydroseeded and it looks like a golf green since last summer. Does the hydro seed just "cling" to anything. Will the substance fill in areas and make them even? Would hydro seeding be the best option for her? I dont know that much about it, but am very interested. I was thinking dumping soil and mixing it with the clay, then seeding, straw, fert, etc, etc. This would be expensive however, 1/2 acre + looking at $1000-$1500 for me to get a tractor for a day and having all of the soil bought in, and other materials. What do you think????
