Grit for Mediterranean Garden

Hi,  I live in Whitby, North Yorkshire and am trying to create a Mediteranean  garden around our new patio.  I have planted the recommended plants and used the agricultural grit which I purchased at the garden centre to add to the soil where my plants are.  Having a bit left over I decided to top dress one of the borders with the remaining grit and it looks lovely.   What I need to know now is do I have to purchase horticultural grit at £5 per small bag or would the grit from the builders merchants be OK to dress the remaining borders.  Also where would I get a large gnarled tree root to start a stumpery.  So glad to have found this site and any replies would be appreciated.

    Builders' grit and gravel tends to be full of sandy bits so maybe give it a rinse before spreading it or else just give it a good wash once spread.    Check it hasn't got lime too if the plants you've used won't like it.  There will be various grades available to give the effect you desire.

    Have you tried the beach for driftwood?   Or maybe ask a local tree surgeon if they can help.

    You can order horticultural grit in bulk online if you need large quantities. You might be able to buy it for less per bag if you shop around, e.g. Homebase does it for £3.99 per bag. At least then you can check that it matches.

    I only use the soi-dit 'Alpine grit' as top dressing for pots. On the actual rockery I use the 10 mm stuff from the Builders merchant. You can buy the 5mm stuff in bulk if you can find a quarry nearby which supplies it. We bought 5 tons of it when we first moved here.
