Q. If I’ve had Miracle Gro sitting around a long time, does it expire? I don’t see an expiration date.
According to Scotts, the maker of Miracle-Gro, it has an indefinite shelf life, which means it does not expire and should continue to do its job even if it’s been sitting around a long time.
If you are looking at liquid Miracle-Gro, like LiquaFeed, the recommended shelf life is up to 3 years but it may be good all the way up to 8 years.
