brown patches on lawn after weed and feed?

Question

After using the weed and feed with a lawn spreader, I notice I have long brown patches on my lawn. What is this and how do I fix it?

Answer 1

if the grass died, you probably over-applied. If the weeds died, it's working.

if you over applied your fertilizer, water!!! you need to leach the soil of some of the fertilizer. it's possible to put too much fertilizer in the soil and it will burn/kill the very plants you are feeding.

Fertilizer is a salt and salt dries out roots.. so WATER!!!!

Answer 2

Your spreader setting may have been off and it applied too much product. I have also seen where people put the drive wheel on the spreader on the outside (walking counter-clockwise and drive wheel on the right side) and this caused excessive dropping at corners. Probably no permanent damage done though.

Answer 3

that may be problem grasses and weeds dying off. You can wait a little while and then replant once the weed and feed has worn off. Good luck. Mine did the same thing.
