Quick or slow release lawn fertilizer in late fall?

Asked October 24, 2018, 11:21 AM EDT

A mid October soil test indicated that a lawn (newly seeded in mid September) needs apx 2.5lbs/1000sqft of nitrogen with no more than .9lbs/1000 sqft per application in the fall or spring.

Any recommendation as to if I should use a quick or slow release fertilizer in late October? Typically I would use a slow release release fertilizer earlier in the fall, but would the slow release fertilizer be of any benefit to the grass in late December and January when it's cold?

Lawn fertilizers now sold in the state are formulated to comply with lawn fertilizer law. Lawn maintenance fertilizers have zero phosphorus in them and contain at least 20% slow-release nitrogen. Here is our page on fertilizing lawns http://extension.umd.edu/hgic/topics/fertilizing-lawns
