Breaking up Clay soil
I have very heavy clay soil. It comes up in big clumps just like the clay in our art cupboard at school! Having done some research, I am hoping to break it down using sharp sand and composted bark. I see that there is such a thing as 'horticultural sharp sand'. The price for this is very much outwith my budget. I was hoping to use BandQ Sharp sand that comes in small bags (I would rather pay more for small bags than buy a bulk bag as I will be transporting it myself (female) round a gravel path). My question is will a cheaper, bargain basement version of sharp sand help to break up my clay soil in the same way as the horticultural sand? It will be a lot of effort to dig in so I don't want to get it wrong and have to redo the heavy work. Thank you for your help.
