I really love this product. It works really well. It keeps your lawn really heathly. I think you can either apply during rain or shortly before it rains, because it's very enviornmentally friendly. I would definitely recommended this product. It's really worth it!
After dethatching and reseeding my new lawn was coming in nicely. I had top dressed the flats to protect the bare areas around the individual blades of new grass but on slopes there was no protection. An early heatwave was expected so I got this to keep from having to wet area 10 times a day to prevent drying out of new grass and it was better than I thought....I will finally have grass on my slopes this summer!
