That is Scotts 4th step I forgot to mention.



You can use it now, it's formulated slightly differently, optimized for
fall, but it's still pretty close to fertilizer used for other times of
the year and will work fine. However, if I were you, in NJ I'd wait
till late April, then apply a fertilizer with pre-emergent crab grass
control. Save the 4th step for fall.
