just wondering if anyone has tips on fertilizers to use in the event that the customer doesn't have an irrigation system. from my years as a golf course super i learned that just about any fertilizer will burn under the right(or wrong) conditions. some of the over-the-counter scott's or lesco ferts. claim use in any conditions. i'm considering trying them and suggesting/hoping the customer run their own hose/sprinkler. some i know won't and i'll be left trying to explain a burned lawn. are these o-t-c products legit or what? i don't want to have to rely on prayers of rain.
