Flowering currant hedge
I have a 10 metre long flowering currant hedge that has a section under which my house services pass. Despite re-planting three times with similar healthy bushes from elsewhere in my garden the bushes in the affected section die off. The hedge is about 14 years old and has had the problem all that time.
Could the roots be affected by the magnetic field around the electricity cable supplying my house as it passes under the hedge?
