Old bags of weed and feed

[ricknielsenshat]

Hi-

I have severaly dandelions in my yard and wanted to know if using weed and feed would kill them. The bag has been in my garage for a couple years...so is it ok to use an old bag.

Also, is it ok to use old grass seed?

Thanks

Depends on the herbicide in the bag. If it contains the chemical

2,4,D, it's supposed kill broadleaf weeds that are several inched high. If it contains the chemical Atrazine, it's supposed to prevent weed seed from sprouting. So if your weed & feed has 2,4,D, it should kill the dandelions.

Yes

Yes, but expect a low germination rate.
