Thank you, Spider. I will take your advice, but my secateurs may not be
razor sharp! I'm in SE London at 62m above sea level. Does that qualify
as "high ground"?

You're welcome .... sharpen them! .... yup, that's high ground:~).

I am on high ground, by local standards - 15 metres above sea level.
