Dawn dish soap is great for a surfactant for spraying weeds but will do nothing to retain water in the soil or to give even water distribution in the soil for any length of time.
I would say it lasts around a month per application. I would say it would definitely help your hill issue. My local SiteOne had to order it from another store for both of them so it took a few extra days to get it. I think most wetting agents have a compounding effect where if you use it consistently you will see more results. I like the idea of the FloUltra as it seems to have more staying power in the soil.
I apply the WetPlus with my Franken Sprayer at 3 gallons/M with my bug and nematode treatments monthly and then I water it in immediately after application. In the past I would just give it a short cycle to wash if off the blades and then a heavy watering in the morning as I generally spay all my applications in the late evening when the sun is going down. I only water it all in after application now due to the nematode applications.
Yes, I am using the liquid for the WetPlus. I have the Tournament Ready Pellets for LDS in the lawn and H2O Maximizer Pellets that I put in my EZFLO for my irrigation.
I think it depends on the size of your lawn as I wouldn't want to drag a hose around to apply the pellets every month and find it easier to apply the liquid since I'm spraying anyway. I feel like the liquid lasts longer too since it isn't as diluted as the pellets. The pellets are great for spot spraying dry/hot spots in the lawn as it hydrates the lawn and applies some moisture holding capacity too.
