decorative slate chippings
This isn't strictly a gardening question, but we have lots of pots and containers in my garden - largely because we can't dig large holes before coming up against bricks and other objects. We have clematis and other climbers - also bulbs, perennials and small shrubs in containers. Chippings conserve moisture, deter slugs, mice and squirrels and look decorative.
I want to find a smallish - 5 - 10kg - quantity of plum or purple slate chippings - to top up these containers, but have trawled through the web, and can only find 25 kg bags. Don't think we could begin to lift one of these, and if we had help to get it into our car, we'd have to lift it out again when we got home!
Any ideas would be very gratefully received. Thank you.
