If you use fertilizer containing weed killer they want you to put it on wet

The broadleaf killer granulars need to stick to the leaves (of the
weeds) to work.


But if you use fertilizer without weed killer they want it washed off of the
grass. Why? Is this fertilizer different chemically?


Some fertilizers can be harsh and may burn the grass. Fertilizer
applied to a damp ground, then watered in are much less likely to
burn.

BTW, in most US areas this is a poor time of the year to be using lawn
weed killer.



Thanks
