how much topsoil

A question about : how much topsoil

hi

just in process of getting some quotes to convert out jungle into useful space with new turf.

Part of it already turf but very patch and large part is raised bed and gravel on weed membrane.

After all junk is removed. how much topsoil should i put in? Obviously topsoil is expensive (was looking online and saw around Ј120 per bag!!!!!.

any other tips! we are in london so its clay....

Best answers:

• I would say that you want two inches minimum for grass areas and up to six inches for plants. I see an advert for ton bags delivered in London to M25 Ј100 or Ј90 per bag for more than one delivered. Google soil-compost co uk, I can't comment on the reliability e.t.c. of this company as I only did a quick google search but it could give you an idea of the price of topsoil in your area.
• Tesco & Homebase doing it at Ј125.00 per 0.9 Kg., but local suppliers were more in the region of Ј65 - Ј75
  But check the Homebase website - 50lt Homebase compost at Ј1.00, & 60ltr Westfield Compost at Ј2.00 may be still going. Clearance price - you'll need to check the local stores - CSD with product code - it wasn't on display when I bought some (on three different days).
