Using up old stuff

[caroline7758]

I'm clearing out my shed prior to moving. It's going to be a while before I get a garden sorted at the new house, so I don't really want to take lots of half-empty bottles etc with me. I'm just wondering whether there are ways of avoiding taking stuff to the tip. I've got the following so far:
tomato fertiliser
aquatic compost (very old)
seaweed feed
Probably other things once I get to the bottom!

Could I put the feed on my compost or would it just feed the weeds? Is there anything that needs a feed at this time of year?
How long do these things last anyway?
