Help will removing conifers cause heave?

[Millie1976]

Hi   I am looking for some advice   Buying a 1930s semi detached house in Birmingham which has 3 large conifer trees (i think they are conifers) in the front garden about 8-10 metres from the house   They are as tall as the second storey of the house and are very bushy.   The house is on clay soil (mudstone)   I like the trees but would like to reduce the height   Would this cause heave?  Surveyor could not find any evidence of subsidence  in the house at present  but did mention caution about the trees and the clay soil.  The front wall is bowing slightly as well presumably from the roots of the trees.   Worried in case i buy the house and then cutdown trees slightly and heave occurs   Any advice?

Neighbor cut down a lot smaller hedge and left the stumps in and took at least 4 or 5 years to fully rot enough to dig out easily with a spade. 

 

Get them ground out, enrich the soil and wait a few months and plant something nice.

Heave is a potential issue if the building is erected on pre desicated soil and then the trees are removed.  Ie, the trees must be mature/sizeable before the building comes along.  You won't have heave. 

Enjoy your new home.

Why?

 

Salt will only make it difficult for anything else to grow there till it washes out over a few years.

salt won't make them rot down any quicker . just stops thing growing . I killed a patch of nettles that grew up round a style that I made . Sprinkled dish washer salt for 2 seasons then they never came back .
