But personally, if he does have that much sand, and also no budget to water, then he's just peeing in the wind, literally.
But, yes, not the best recommendation at all. My experience from sandy soil is that if you have a full sun lawn, the water you put down in the early am is going to be gone by noon if you have low humidity, a strong breeze, no cloud cover, and super high temps like you are seeing now.
Even if you were to water at 3pm in that situation specifically, then the foliage should dry out completely by the evening.
I think its really sandy soil. I can take a picture so you guys can tell me what you think. I have some issues that make this hard to figure out. The distance on the rotors is ~35-40' radius (so thats a large circle). The pressure is not hte best since i am 550' from the road. The nozzle sizes are not huge, about 2-3GPM per head, and mostly 2heads on a zone, some have 4 but they have smaller nozzles. I have 16zones so when you add all that up, the time for each zone, sandy soil, full sun yard from dusk to dawn, it makes for a challenge. I will get some pics. Be back later tonight after dinner
