Yes, I use it all the time as I have clay soil. I always add some around bulbs and mix it in with potting soil.

I use it as well. I inherited about a ton of the stuff when I bought my little datcha (cottage) last year...and I have got to get rid of it some how, !! so I spread it on the bottom lawn that gets very wet when it has rained as it is on the bottom of a slope. I also use it when I make stuff out of hypertufa.

I understood it was too fine and you should use coarse sand instead. Good idea to use it for hypertufa - did it work on the bottom lawn? I have some left over but have never put it on the garden.

I thought builders sand contained too much salt for gardens?

True builder's sand has to be salt and lime free to use in making concrete and mortar, but there are many generic mixtures going under that label, too. I have found that the local hardware store's "builders sand" is coarser--and therefore more useful in the garden--than their play sand or "all purpose" brands.

Bricklayer's sand is 'soft sand' which is unsuitable for horticultural purposes as it is too fine and will clog soil particules. You can use 'sharp sand' which is useful for breaking up heavy soils and improving drainage. True 'horticultural sand', although it is at a premium price, contains no lime so it is suitable for compost mixes and ericaceous plants.

Thanks to you all, one the basis of your replies I am going to use it as part of an Autum top dressing for my grass patch, Thanks everyone

Jimmytheone's advice is correct. Only sharp sand should be used horticulturally. Builders sand should not be used.

Thanks Jimmythe one I knew there was a reason not to use it.
