Oh, and I have to mention one lady who does all of my book covers in cross stitch and frames them. Muriel. She's amazing. I just received one for my latest, Love And Dr Devon, actually. It's very sweet of her to do it.

Airports - they're not my idea of fun at all. Some of the staff are lovely, but you do always get one or two that seem to forget that it's actually costing you a lot of money to be there and be insulted by their surliness. Times have obviously changed and we need to get used to being more strictly vetted, but they could be more pleasant about it. A smile wouldn't go amiss.

I get up to 400 letters a week, so I have a full-time PA, but I try to answer everything. People don't seem to realise that if they send something living in the post it's going to die on the way. Especially when you wrap it in a polythene bag.

Once I was on a plane and a woman said to me, 'Now, what's the matter with my tomatoes?' And I said, 'Well, it's a bit difficult to see from here.' She took offence and said, 'I was only trying to be friendly.'

At school I was called Fred, which is my middle name. At that time, Fred was considered to be a bit of a horrible name, so that's why. Otherwise, I was called Titchy because I was little. I was still only about 4ft something when I left school. I grew a foot under glass in my first year as a gardener. It's really quite amazing what sun and manure can do.

I wish we could grow up about it, I'm sure we are contributing to global warming, and we must do all we can to reduce that, but our climate has always changed. The Romans had vineyards in Yorkshire. We're all on this bandwagon of 'Ban the 4x4 in Fulham'. Why didn't we have global warming during the Industrial Revolution? In those days you couldn't have seen across the street for all the carbon emissions and the crap coming out of the chimneys.

Georgian England, to see those wonderful houses being built. And the clothes were interesting too, although I wouldn't want to wear a wig. It's also the most beautiful period of English landscape gardening. They had famous gardeners like Capability Brown.
