Old Canna

[Poontanger]

Hi all,
I have had some canna Coco A + b brand new unopened in my shed for about 4 years,, does it degrade much overtime ?
Has anybody used out-of-date nutrients and found there was no difference ?
The canna site says it has a shelf life of 3 years,(but they are trying to sell it) they also say it will never harm plants in anyway but MAY be less effective overtime
Any thoughts

Over time you can get precipitates falling out of suspension.

canna are usually semi clear bottles so check what amount of crystallisation is happening In the bottom.

if there’s no crystallisation then you’ll be fine to use them.
