Hydroseeding problems- ok this is the first year we have hydroseeded, and still learning. The lawns that we have done seem to do really well in the shade areas, but in the sun areas the weeds grow faster than the grass. The rye comes up within a week, but then it is like the grass stunts and stops, then the weeds grow and take over. We are buying the expensive seed from lesco also!! Any ideas on what I am doing wrong and what i need to change. All the lawns even at the begining of spring look rough.
