Len it does sound as though it's hanging in there. When I asked about new build it's because quite often there is rubble bricks and heaven knows what hidden under the new turf.
Nothing wrong with clay high in nutrients but water logs and dries out quickly, I garden on clay but add well rotted farmyard manure and home made compost to bulk it out.
I'm not knowledgeable about trees so I hope you take advice from other posters, smart folks on this forum
