After a long cold winter like we have had, getting outside is what everyone wants to do. Like you, I also want to start working in the yard. As I look at my yard, I see patches that are bare. However, one pitfall to avoid would be to put grass seed on the lawn now. It is too early; be patient. Remember, in order for grass seed to germinate, the ground temperature must be 65 degrees or warmer.
Another common mistake would be to put pre-emergent on your lawn this time of year. Everyone wants to prevent weeds, but the pre-emergent is only effective when the ground temperate is 65 degrees or warmer.
Save your pennies. Wait to put grass seed or pre-emergent down.
Finally, use a general fertilizer on your lawn if you plan on putting grass seed down. Pre-emergent would prevent your grass seeds from sprouting.
