When I first started in the garden profession years ago I naively thought that topsoil was topsoil, every supplier had the same soil, just selling it at different prices. How wrong could I be? The bulk bags would turn up and often were turned straight away. I've seen bulk bags made up of 70% clay, excavated soil from demolition and soil with huge quantities of peat (to bulk it up and give the appearance of good soil) Another trick some unscrupulous suppliers use is to have a few inches of good topsoil on top of inferior soil below. Once it's paid for and loaded off the truck you'll find it extremely difficult to get it picked up and refunded off an unsavoury supplier. Another factor to take into consideration is Japanese knotweed, if you don’t use a reputable supplier where the soil is traceable and passes quality control then you could be inviting this monster into your garden.
As a garden designer and plants man I need to rely on a supplier that will provide me with consistent and top quality topsoil which is why we only use Rowlawn Topsoil.
