I'll be airating/ oversowing an area with a Sydney/princess couch mix on saturday. The PH........51/2 - 6 region......so I don't think It'll need much conditioning. The Soil structure is clay base...........So I'm going to apply a liquid gypsum. My main issues are. #1. I don't know if I should put the seed above or under the topdressing mix?? (Putting down a very thin layer of this top dressing mix) #2. I don't know really how to spread the seed even.I have a walk behind fert spreeder and wonder if I can use this?? (I am going to be spreading a seed starter fert mix and have 4kg of seed) #3 How many times should I run the Airator over the area?? #4 I will need to be there every day watering............Yeh??? (it's our spring) I don't want to ---- up this job as I think I have over charged and want to make sure these nice people get what they are paying for. I know..............I should really know all this. I'm a sod man and have never delt with seed before..........Any help........Thanks!!
