Ok I have been at it 3 years but I don't get many new lawns to fertilize. I have an old customer who moved into a new home and wants to become a new customer again. This gent is meticulous and wants the lawn looking nice. He has a newly established KY blue/red fescue/rye mix. He waters the lawn and it is in decent shape. I asked and he thinks that the hydro seed guy put 10-10-10 on about about 5 or 6 weeks ago. I am a strictly granular applicator so I am looking for any input that you may have. I'm looking for formulation, iron or not? I have access to granular with 4% iron. I have no problems with using lower % SCU/PSCU ect as he waters and will do as I instruct. What application rate do you prefer to use? Also, I know the time is not right but would it be OK to spray Millennium Ultra in the fall or should I wait until next spring. Let me know what you think and thanks.
