Old Weed & Feed From Last Spring (2 different bags) OK To Use?
Whew. It's been a long cold winter here in Suburban Chicago. I was on on my way out to stock up on some springtime weed & feed for my lawn, but I've noticed I have many bags left over from last year.
1x Sta-Green Weed & Feed Phosphorus Free (opened package)
1x Scott's Turf Builder with Plus2 Weed control (Sealed)
2x Sta-Green Winterizer
Q : Is the opened bag OK to use? is there an expiration date of the un-opened bags?
Q : Ok to mix the two weed and feeds together for spring time application?
