We have a lovely mature (10-15 years old) Camellia very close to the
boundary of our property near the house. Its around 10 foot tall now, Im
planning on pruning it back to 8ft after its flowered.

We are in a semi-detached house. The attached neighbours are planning a
single storey extension at the back. If the foundations go to the
boundary and cut off half the roots how likely is it that we will have
an ex-camellia? Is there anything we can do to save it?

Thankyou
