I got my 15,000 sq feet backyard hydroseeded 2 months ago. I am in NJ. Lesco Athletic field mix, starter fert and wood fiber mulch was used. It came in pretty good in 3 weeks. Then the pithium hit and killed a pretty big section. The full sun area is full of crab grass. The only part of the yard that looks good is the shady area. The hydroseeder told me to put more starter fert down at the 3 week mark and 2 days later is when the fungus started. IT was very humid and moist. The wood fiber mulch was like the perfect breeding ground for the fungus. I put down antifungiside but it was too late. I want to spray for the crabgrass but It seems like it is too hot 85-90. Should I live with the weeds and patchy pithium areas untill Fall or is there something I can do now? I am very disapointed in the yard and wished I waited untill Fall.
