New lawn - should I be worried?
We've just had a new lawn laid but I'm a bit concerned about how it's been done. When the gardener came to quote me for the work I had said that we wanted the old lawn removed and replaced, but it's now been laid and I've realised that the new turf has been put directly on the old turf. I don't think there has been any kind of prep and doesn't appear to be any top soil, just directly onto the old lumpy, stony, weedy lawn. I've no experience with these things but I am now worried that I've got a new lawn that has no chance of survival.
Am I right to be worried? I'm not too concerned about the lumps or weeds but are there any tips for helping it to survive?
