The warnings are the product as a whole, the MSDS however will change depending on the packaging. Its always pertinent to know what size packaging you have when requesting an MSDS. Obviously a gallon container and a 50 gallon drum present separate hazards.

As far as the miracle grow assuming its not a full bottle I would just crack the top to allow venting and let it stay in the shed. Most plastics can handle the cold however their resilience to change is less tolerable the colder they get. Meaning the expansion of ice within the bottle will crack the bottle, or dropping the bottle may cause the plastic to shatter at sub-zero temps. Depends on the type of plastic.


Assuming to will stay untouched in the shed I think it'll be fine.

Most warnings are written on bottles, if not you can look them up on the manufactures website. If they don't have them there I wouldn't use their product...but you can call the number on the bottle (or request via website) for the MSDS and they have to send it to you...it's a legal issue.

That being said many chemical fertilizers or weed controllers that consist of primarily water, will not store below 32°F and have the same qualities when thawed. Due to how the crystalline structure of ice alters the blend, which is why you can't freeze WB paint. However some will be fine it depends on the product.

Dry seed will be fine, in fact seed reserves are kept in suspended animation in certain vaults at temperatures well below temps many places on earth ever see.

Thanks for the reminder I got a tote of spray paint I need to bring inside!
