Buckland said: "Heading up Gardeners' World - my first responsibility is to gardeners but I do care about the industry.
"There's a theory in gardening that you should only visit small nurseries and grow as much as you can from seed. That's perfectly good but I want to broaden Gardeners' World's appeal and make it acceptable for gardeners to visit garden centres while highlighting what's on sale at garden centres now. I believe gardeners need to be shown how to shop for things and encouraged to support the industry. It shouldn't all be about growing your own as cheaply as possible."
Buckland added that he uses chemicals-something his Gardeners' World predecessor Monty Don opposed: "In some cases it's better to be an inorganic success than an organic failure and never pick up a trowel again.
"Growing your own and saving food miles is the single most important thing you can do. And if that means you clear your allotment with glyphosate and then go on to be chemical-free, it's common sense."
On peat, he said: "Even the gardeners at Kew, who have been peat-free for years, say some plants need a little peat in their potting mixes - citrus trees, for example. So if we talk about growing lemons, we'll recommend peat as one of the ingredients. We won't ignore the issue - we'll be honest to help viewers."
HTA commercial services director Andrew Maxted said: "He came over as a gardeners' gardener; loving his subject and prepared to share his tips, hints and shortcuts.
"With his evident horticultural knowledge, his years (enough, but not too many) of practical gardening experience and his obvious presentation skills he is a very worthy successor to Geoff Hamilton and Alan Titchmarsh yet from the outset is impressing his own personality on the show," Maxted added.
