I've got a relatively young yard, I seeded it 2 years ago this May. Unfortunately, a thunderstorm blew in later in the week and blew much of the seed away so the grass didn't come in terribly thick and the weeds filled in. So the question of the day, do I go with a "weed and feed" application or a fertilizer with crabgrass preventer? Last year, I applied a fertilizer with a crabgrass preventer and minimized any crabgrass growth, but I didn't make much progress against the other weeds. My gut says to apply the weed and feed this year. I live in Iowa so we are just this weekend starting to see a little greening up of the grass.

Thoughts?

Weed&Feed I would use. Crabgrass preventer will not let grass seed germinate if you overseed your lawn. :trink40:

If you are planning on seeding very soon, use the weed and feed. If you are looking at seeding in the fall, a crabgrass preventer in fertilizer would be good to use (Dimension is one product) Crabgrass preventer prevents any seed from germinating for at least 3 months.

Weed and Feed has zero effect if there are no weeds actively growing; the bag should state this in its instructions. The primary weed-killing ingredient is usually 2,4D which is only effective when absorbed through the leaves.

Forgot about that (dont use it) and the grass must be wet from either dew or rain when you apply it, otherwise it wont stick to the leaves and be effective.

Scotts makes a starter fertilizer with crabgrass preventer just for this purpose. This has been a issue that has bothered me for years. I plan to try this in one of my my lawns that needs seeding real bad but gets invaded by crabgrass.
