They should cause no problems. Best left alone.

We have had three very large conifer trees cur down from our garden
leaving
stumps up to 24" across. Although unsightly these should disappear beneath
the new planting.

Is it important to remove the old stumps? For example could they harbour
diseases that could damage the new plants? Can I just leave them to rot.

Any views or experiences very welcome.

Thanks
