I just finished seeding parts of my lawn (where the crabgrass and
other unfavorable grasses were before the cold weather started to make
them "go away") with a mix of KY Bluegrass, fescue and perennial rye.
Should I also fertilize now, do I need to wait, or should I not
fertilize at all? I am new to the area (Long Island) and have heard
about "winterizing" my lawn but don't know what that is exactly. Any
help would be appreciated. Thanks in advance.
