For those of you who do this -- what do you do with the "used" vermiculite after removing the seedlings? Do you dry it out and re-use it for seed starting? I've been thinking about doing that, but it seems like there could be a potential for seeds being left in the vermiculite that will sprout later -- or, maybe not? TIA...

I use it over and over until it starts to grow algae or has too much detritus in it - then I let it dry out and incorporate it in my potting mix.

If I reuse it for new seeds--I leave the old label on, as well as a new label, so I will know what any rogue seedlings are.
Most of the time I dump it so it can be added to potting soils.

Leaving the old label sounds like a good idea Caroline... I could avoid planting something similar and confusing the sprouts that way.

I usually recycle it by dumping into the compost or a flower bed or flower pot...

Thanks, Karen -- I think that may be the route I end up going with it!

Compost heap. I never, ever reuse seed starting media. Ditto for last year's potting soil from containers.

I reuse it. Not for houseplants or any really special plants. But I have gophers big time so I pot a lot plants. Many are succulents or plants that aren't soil picky and think they've got it good in used potting mix, I mean beats the hell out of my sandy soil. I haven't tried just vermiculite for starting seeds, I do use it as a top cover in seed trays though.
