Thank you Alan but I was wrong to discount any work that Martin had put into
his response. I have spent my working life researching. It is very easy
for me to do that but I am enjoying the ideas and friendly discourse here.
It is so much nicer to talk. For example, when I asked about waiting to
plant my potatoes until the shoots had appeared, Steve was able to tell me
that :

"There is disagreement every year about whether it actually achieves
anything anyway"

I probably couldn't have found that by googling. I am able to access the
knowledge and experience of real people here.

Nevertheless, I do apologise to Martin.
