I’m going to be renovating my garden early next year. It’s currently a grassed garden which has been untouched since it was build around 1975. The estate was built on fields and the garden is that original field land so I have all sorts of wild flowers etc. growing in the amongst the grass. There will be a sandstone patio going down, new drainage, the garden will be levelled and a small retaining wall put in, the remaining area of around 100sqm will be a new lawn (The existing grass will get ruined during the works) and my question is this… When levelling the garden I will remove the turf and get the area nice and flat. Will I be best digging down around 100mm, sifting through all the old soil to remove any crap and laying a fresh new 100mm layer of topsoil in preparation for either seeding or new turf (what would you recommend for this also).
Thanks in advance.
