The research, commissioned by The National Garden Scheme (NGS), highlights how the perceived physical and emotional health benefits associated with gardens can last well into adulthood.
Some 92 per cent of those surveyed say time spent in gardens at a young age promotes an active and healthy lifestyle in later life; while one in three adults admit they still associate gardens with happy childhood memories – recollections of time spent with grandparents, of games with friends and siblings and the freedom of exploring the natural world unsupervised.
Some 79 per cent of the 2,000 adults surveyed by the NGS said children who spend time in gardens are likely to be happier.
NGS president Joe Swift said: "While it may seem like common sense to say that children who spend time outdoors are more healthy than those who stay indoors glued to a screen, there has been a dramatic change in the amount of time kids spend outside in recent years.
"24hr TV, the internet and computer games mean there often isn't much incentive for them to get out in the garden anymore. The tragic truth is that children have lost touch with nature and the outdoors in just one generation."
