Laying turf over old turf?
Possibly a very stupid question but friends and family have said it doesn't really matter so i thought i'd ask people that actually have some knowledge in this area!!
I laid turf last year and to cut a long story short a combination of not enough topsoil put down beforehand, a pet dog with a penchant for subterranean activities and a harsh winter have left me taking the easy if more expensive option and deciding to relay turf this year.
My question to you all is this...
Would I be wise to take up the turf and flip it over before adding more topsoil and re-turfing as seems logical if a lot more work,Or as some friends have said just topsoil on top of the old turf and then re-turf on the assumption that the old grass will die and provide further nutrition?
Many thanks for any advice.
