53 Year Old Terrarium

Thriving since 1960, my garden in a bottle: Seedling sealed in its own ecosystem and watered just once in 53 years.

  • David Latimer first planted his bottle garden in 1960 and last watered it in 1972 before tightly sealing it shut ‘as an experiment’
  • The hardy spiderworts plant inside has grown to fill the 10-gallon container by surviving entirely on recycled air, nutrients and water
  • Gardeners’ Question Time expert says it is ‘a great example just how pioneering plants can be’

To look at this flourishing mass of plant life you’d think David Latimer was a green-fingered genius.

Truth be told, however, his bottle garden – now almost in its 53rd year – hasn’t taken up much of his time.

In fact, on the last occasion he watered it Ted Heath was Prime Minister and Richard Nixon was in the White House.

Still going strong: Pensioner David Latimer from Cranleigh, Surrey, with his bottle garden that was first planted 53 years ago and has not been watered since 1972 - yet continues to thrive in its sealed environment

For the last 40 years it has been completely sealed from the outside world. But the indoor variety of spiderworts (or Tradescantia, to give the plant species its scientific Latin name) within has thrived, filling its globular bottle home with healthy foliage.

Yesterday Mr Latimer, 80, said: ‘It’s 6ft from a window so gets a bit of sunlight. It grows towards the light so it gets turned round every so often so it grows evenly.

‘Otherwise, it’s the definition of low-maintenance. I’ve never pruned it, it just seems to have grown to the limits of the bottle.’

The bottle garden has created its own miniature ecosystem. Despite being cut off from the outside world, because it is still absorbing light it can photosynthesise, the process by which plants convert sunlight into the energy they need to grow. [… continue reading & watch video]

Do plants ‘veto’ bad genes? : Nature News & Comment

Heidi Ledford
08 February 2013

Two publications are seeking to resurrect claims that plants can reject the inheritance of a mutated gene from their parents, in favour of a healthier ‘ancestral’ copy from their grandparents.

12401Susan Lolle, a plant geneticist now at the University of Waterloo in Canada, and her colleagues first published evidence in 2005 that plants had passed on genes correctly two generations down, even though the genome of the generation in between had only a mutated version1. This type of inheritance would require some hidden reservoir of genetic information outside of DNA, some suggested — perhaps in RNA transcribed from the healthy gene, which the plant would then use to correct the mutated one. If true, those findings would upend the modern concept of genetic inheritance, and predictably they have met with considerable scepticism. [ … continue reading ]

Adding Bark To The Ash Borer Bite

Article by: Bill McAuliffe , Star Tribune

Four dogs, trained to sniff out other invasive pests, have been in the state since April, learning to detect the insect, larvae and wood.

ashborer-dogMinnesota now has several dogs in the fight against the emerald ash borer.

In a first-in-the-nation strategy to contain the pest, state agriculture officials have hired dogs to sniff out ash borers and their larvae before they might be carried out of infested areas.

Four dogs, already trained to find endangered species of plants and animals, other invasive pests and even human remains, have been training in Minnesota since April to detect both ash wood and ash borers.

At a demonstration Tuesday in Arden Hills, two of them — Denali, a shaggy, 10-year-old German shepherd from Reno, Nev., and Wicket, an 8-year-old Lab from Three Forks, Mont. — bounded over a tangled pile of waste brush and a 5-foot-tall mulch pile before proudly discovering their prey, each in about two minutes.

“We smell parts per thousand. Dogs smell parts per trillion,” said Aimee Hurt, co-founder and director of operations for Working Dogs for Conservation, based in Three Forks, whose eight dogs have tracked Chinese bush clover in Iowa, rosy wolfsnail in Hawaii and brown tree snakes in Guam. “They’re a magic combination of really good sensing abilities with an interest in communicating with us.” [ … continue reading ]
