What to do with last years growbags/compost?

RHYSDAD

What can I do with last years growbags and compost? I grew runner beans in the growbags and toms and cucumbers in the pots but I still have the compost in them! Can I incorporate it into my containers this year or should I chuck it? I'm aware that it's spent so I'll need to add a fair bit of growmore or similar!

No harm in reusing it just ensure you avoid reusing it on the same family type of plants, your bean bags could be tipped into potato grow bags for example, just mix in a drop of fresh compost and some fertiliser along with it. However don't mix the tom's in with it as this will encourage blight. Just make sure it's rotated round and you should be fine, shouldn't be any problem throwing it into a compost heap either, this will allow it to go dormant for at least a year.
Just to add, only time you will need to get rid of it is if disease sets in, i would bin it then and sterilize your pots.

Re-use it in containers (with some fresh & added nutrients as Wookey says), top up raised beds, or put it elsewhere on the garden as a mulch.

This isn't really an MSE answer, but I wouldn't re-use it, personally. You can't tell what proportions the main fertiliser elements are in and you can't know what plant pathogens could be in there.

If it were me (and I understand opinions differ) I would either compost it or use it as a mulch/soil improver on ornamental beds.

Growing bags are pretty cheap and it seems a shame to run risks with a year's crops.
