UKTV Gardens: What's your favourite style of garden / garden design?
Tommy Walsh: "Low maintenance!"

UKTV Gardens: What is the coolest plant in the world and why?
Tommy Walsh: "One that's just come out the fridge? Only joking. The coolest plant in the world is the phoenix palm because it's a big beautiful plant."

UKTV Gardens: What was your biggest gardening cock-up?
Tommy Walsh: "We were doing a contract for somebody - some hard landscaping - in the winter. There was a lot of very fancy ornate pointing to it and we had an overnight frost. Three months later, all the work I had done separated from the base below it. It looked like an absolute disaster so we had to rip it out and do it all again. It cost me a fortune and it'll be indelibly printed on my memory forever. You shouldn't ever do any cement work in extremely cold weather. Or in extremely hot weather."

UKTV Gardens: Is the changeable British weather a gardeners' friend or foe?
Tommy Walsh: "I always thought in my professional career before I started TV work, that one of the golden rules is never to do hard landscaping in bad weather. But obviously TV producers don't understand or listen to that, cause we only ever have two days to film and we have to work in all kinds of weather!

"The one advantage I suppose that has worked for me and not for Alan, is that working in the rain and all this manure has made me grow to six foot five, while Alan has remained five foot seven and three quarters! He says every quarter of an inch counts. And his wife says it's true!"
