New David Attenborough series Secret Garden gets release date confirmed to mark broadcasting legend’s 100th birthday

A new documentary featuring David Attenborough will premiere on BBC to celebrate the renowned broadcaster’s 100th birthday.

Secret Garden is a documentary showcasing the amazing plants and animals living in everyday gardens. It was created to honor a very special birthday – a celebration for someone about to turn 100 years old.

You can watch the new documentary on BBC One starting Sunday, April 5th at 6pm. All episodes will also be available to stream on iPlayer right away, and the premiere coincides with Sir David Attenborough’s 100th birthday on May 8th.

I recently watched “Secret Garden,” and it’s a truly lovely five-part series. Each episode takes you to a different, wonderfully untamed garden somewhere in the UK. What really struck me was getting to meet the passionate people who’ve created these spaces, and seeing all the wildlife that calls them home. It’s a really charming and relaxing watch.

From pine martens in the Scottish Highlands to blue tits in Bristol, and from dormice in Wales to otters in Oxfordshire, this series uncovers a hidden natural world all around us.

The BBC is launching a week-long event to celebrate a major achievement, and as part of it, they’re releasing three new shows, including ‘Secret Garden,’ and revisiting some beloved nature programs narrated by David Attenborough.

Next month, a new documentary called Making Life on Earth: Attenborough’s Greatest Adventure will be released. It includes never-before-seen interviews and footage showing the challenges of creating the groundbreaking 1979 series, Life on Earth, which took three years and spanned 40 countries to film.

A special event, “David Attenborough’s 100 Years on Planet Earth,” will be held at the Royal Albert Hall to celebrate his life and work.

In the trailer for Secret Garden, a naturalist observes that gardens throughout Britain are truly magical places.

Secret Garden reveals a hidden world brimming with incredible animals, captivating stories, and unexpected surprises – all right here where we live.
