Thank you for your replies to the question about poplars. The reason I am asking is because our neighbours have two poplar trees which are about 50 feet from our conservatory, and we are experiencing subsidence there. We love trees and have not asked them to remove the poplars, but just cut them back so that the demand for water in our clay soil is not so great. They to are experiencing movement in the soil because their paving slabs are now uneven and rocking as they are walked on.
