Liquid fertilizer - does it go off

[Woofster]

I have various containers of liquid tomato fertilizer, general fertilizer and seaweed liquid which I have had for some years - say more than three or four. Can I still use them or should I just chuck 'em ?

[terrier]

If it's in liquid form in stopped bottles, I would assume a long shelf life. If you use it you are unlikely to do any harm to your plants. In future, make your own (maybe it is your own), for now, I would use as directed. Waste not, want not.

Hmmm?????? Never thought of this! I have half a barrel of homemade Comfrey tea, probably about 20 gallon all told!
I wonder if it still stinks? Once the barrel has thawed I'll have to have a sniff.........either way I'll still be using it!

[lynda66]

i'd use it too

[Flummery]

I'd use it too. How can you tell if comfrey tea has gone off Snadger? It smell off when it's good? Maybe if it smells nice now, it's past it!

[Woofster]

Thanks, everyone. I shall not chuck the stuff but use with confidence. I guess the worst that could happen is that it won't be that effective.

Left a barrel of seaweed tea over winter once...smelt like an open grave....truly horrid.

I found the comfrey barrel lid blown over the allotment the other day and I have to say it didn't seem too offensive. None the less; I'd water the compost heap with it to help that along and make fresh 'tea' for next season.

It should be well 'masked' by now. Lol!

I was wondering the same thing as I have some liquid seaweed a couple of years old. I must use it up this year.
