well looks liek alot of sweat went into that site prep
I would stronglu suggest you fertilize now, new seds ned it as soon as they get growing
and I would , unless your soil test said no nitrogen, add some ,
clover will make its own but needs it to get started!!
good luck , post some pic's as it fills in
just got all my chemicals will be spraying next week, to a few plot sites I have
good luck hope you get good weather now too!!
