Soil used for seedlings

Having pricked out seedlings I'm left with remnants of seed-compost mixed with perlite, which should be pretty low in nutrients. What do I do with this soil? I don't have a compost bin (on next years to do list) but next door does - is it ok to add to his bin? Can it go on borders - I don't see that would help them? Otherwise what should I do with it?

 

You could put it on next doors if you ask nicely. They might even give you some compost back for it

 

Personally I put all compost that I'm not going to use potting up etc. onto the borders.

Especially any old stuff from last year as that loses it's strength, can't think of the proper word but you'll know what I mean :D

 

If you (or a neighbour) has clayey soil you could always dig it in there. Won't help much nutrient-wise but it should help break up the clay

 

Thanks guys. Cajary gets my vote - my soil is naturally sandy but I have a friends whose is clay - I'll pop it in a compost bag and take it over net time. Stingo I do the same with general use compost or Innes 2 or 3.
