Growth in garden thefts
A booming business - but so is stealing such items
More than a million gardens are raided every year in the UK in what police are referring to as an epidemic.
Microchips embedded in trees and plants are thought to be the high-tech answer to a problem which insurers say many dismiss too easily.
For victim Elisabeth Ruiz it was not just the loss of two expensive bicycles from the shed that hit home.
She says it was the invasion of privacy: "To feel that people could get into the garden so easily. I must say I then realised how vulnerable we are."
Insurers believe most people pay little regard to the security of the area surrounding their house, even if they are careful about the building itself.
She believes people are not aware of the value of what they have in the garden.
"Once you get outside you think, 'oh well it's only a spade or a statue. No-one will bother to take it'."
But anyone with such an attitude is clearly wrong.
Ten garden sheds a day are being broken into, with £12,000 worth of garden gnomes alone likely to be abducted this year.
There are more spectacular thefts too, with hedges, lawns, and ponds taken away.
It is all a reflection of what is a booming hobby and business - worth £2.5bn a year in the UK.
Martin Unwin's firm called Bon-Tag, is fitting electronic security tags to bonsai trees.
Each one has a unique serial number when scanned.
Mr Unwin says people are very protective of their bonsais.
"They are irreplaceable to the people because they are like their children - they have created them over a period of time.
"They give a lot of time and effort and materials and there's a great sense of loss."
