Gotta check a lawn tomorrow. It's been 2 weeks since I applied. Rate was 1 oz per gal. Temp was 80 4 gal and covered 3400 sq ft. ----------- She was having her sprinklers turned on for the season 2 days after I applied. I have no way of verifieng that. I told her to irrigate it within 24hrs after I applied. And it was written on my application sheet which includes all pertinant info. We'll see.
