Loam based compost

I've recently found an old bag of loam based compost in the back of the garage. It has never been opened and says on the back that it shouldn't be used from season to season as the chemical balance may be affected. Does anyone know if this is true? And, if it is ok to use, can I use it as general multipurposed compost or should it be used on specific plants? It is probably about 5 years old!!!

Also, I bought some winter indoor Daffodils last year. They did really well but does anyone know how they should be stored. At the moment, they are just loose in the garage. Should they be in compost or inside a dark bag? Any ideas very welcome.

Thanks!

 

Its said that loam based, (John Innes) compost deteriorates after a few months.

If I had a 5 yr old bag I think I would just scatter it in the garden and buy some fresh stuff.

The daffs should still be growing now and not dried off for at least a month or two.
They need to grow on, after flowering.
To make a decent bulb for next year

 

Thanks, I will scatter the compost as you suggest. The Daffs are indoor ones which finished flowering in December. All their foilage has dried off!
