^^ The 'bumf' for Picea Pungens suggests the following:
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils and can grow in very acid soils.
Therefore if I purchase a new picea pungent, but locate it in a different part of the garden (were in fact I've moved the 'perished' one to), away from the patio and lime might I be ok? The lime from the patio slabs may explain why my run of buxus have expired there (at least half of them) but not elsewhere in my garden.
I'll pick up a tester before I do that anyway.
Just for future reference, could I place in a sheet of perspex (or similar) vertically into the ground where patio slabs are?
