I'm starting a side business with my son aerating lawns. I'm pretty familiar (I think) with lawn care, but I have a question that affects efficiency. In order to protect sprinklers from damage, we need to flag them first, which means opening each valve for a few seconds. This moistens the lawn a bit which I believe will cause even pelletized fertilizer to dissolve enough to potentially burn the lawn if it is not then watered in. We'd rather put down pelletized and tell the clients to water w/i 24 hours instead of having to take the time to cycle all the valves through (time=money). But I've heard of guys who put down pelletized and drive off, but they must put it on dry lawns. But if they do this, then they aren't finding the sprinkler heads and are risking damaged heads from the aerator (mine is 400 pounds). What's the best system, or is there a fairly high nitrogen pelletized out there that won't make me have to water in even though it was spread acrossed moist lawn? Thanks.
