    I put them in with the other kitchen waste and they go into the garden compost bin with grass cuttings, weeds and other plant material so they make up a TINY proportion of the whole. I wouldn't put them straight on the soil but I believe some people do to deter slugs.

    I use them either in the compost and sometimes as a slug/snail deterrent in the area where I grow some Hostas ... it’s conveniently just outside the back door 👍 

    Theres no point in using them ’as a fertiliser’ as they do not contain a significant amount of useful minerals etc.  They may, if you use enough) slightly increase the acidity of the soil on a temporary basis and again, if you use enough they increase the organic content of the soil and aid water retention etc. but they won’t increase the fertility per se.

    No, because we don't drink coffee.  But if we did, I'd put the grounds in the compost bin with the veggie peelings etc.

    I clicked yes, but I do mix them in compost bins,   They’re not a fertiliser but a soil improver, anything organic you can dig in is good.

    Mine go in the compost bin with the rest of the veggie waste.  The finished product is more of a soil conditioner than a fertiliser.

    I always put mine on bits of soil that need improvement,and lots round the Rhododendron,as the soil is alkaline. The worms love them.

    I wouldn't expect them to be a fertiliser but I often sling the dregs from the cafetiere on the garden

    Maybe not so much as a fertilizer, but more as an amendment to improve the overall texture. Used loads in February-March and mixed with household compost to create a vegetable garden bed that had a lot of heavy clay underneath. The worms loved it, and it has seemed to keep the slugs out of the vegetable garden all throughout the summer.
