There's something that happens when you step outside and sink your hands into the soil. Something that no to-do list, no screen, and no cup of tea quite manages to replicate. It's not just a feeling — science is catching up to what gardeners have always known: gardening genuinely improves mental health and wellbeing, in ways that are measurable, meaningful, and available to almost everyone.
Whether you're tending a full plot or a single pot of herbs on a patio, the benefits are real. And for older adults or those who find their garden harder to manage alone, having a companion to garden with can make all the difference.
What the Research Says About Gardening and Mental Health
The evidence has become hard to ignore. A 2024 umbrella review published in Systematic Reviews — led by researchers at King's College London — analysed 40 separate studies on gardening and health. The conclusion was clear: gardening has a significant positive effect on wellbeing, reducing depression, anxiety, and loneliness, and improving quality of life across all age groups.

A separate systematic review in PLOS ONE found consistent evidence that regular gardening contributes to improved mental and physical health — and crucially, those benefits extended to community and group gardening settings too. (PLOS ONE study)
Gardening Reduces Stress — and You Can Measure It
One of the most striking findings is what gardening does to our stress hormones. Studies have recorded actual reductions in cortisol — the hormone your body produces under pressure — following gardening sessions. A randomised controlled trial with 291 participants found that gardening significantly reduced both perceived stress and anxiety, with the greatest improvements going to those who started out feeling most overwhelmed. Even complete beginners saw measurable results within their first season. (RANG Study)
There's Something in the Soil Itself
Here's a finding that never gets old to share: there's a harmless bacterium living in healthy garden soil called Mycobacterium vaccae. Researchers at the University of Bristol discovered that exposure to it triggers serotonin release in the brain — the same pathway targeted by many antidepressant medications. When you dig, weed, or pot up plants with bare hands, you're absorbing a natural mood-lifter through your skin. (The neuroscience research)
Gardening Together Multiplies the Benefits
Group and companion gardening carries an extra layer of benefit — and this is where the evidence becomes especially relevant for older adults. A 2022 meta-analysis reviewed 24 studies on group-based gardening interventions and found significant reductions in symptoms of depression and anxiety, with connection and shared purpose playing a key role alongside the gardening itself.

This isn't surprising. Loneliness is one of the greatest risks to health in later life. Gardening alongside a companion — someone who knows plants, knows how to listen, and turns up each week — addresses both at once.
Staying Connected to Your Garden Matters
Many people reach a point where their garden — once a source of immense joy and pride — starts to feel like a burden. Mobility changes, health challenges, or simply not having anyone to share it with can all get in the way.
That's exactly why Your Garden Companions exists.
We're a Community Interest Company based in Cumbria and South West Scotland, and we work alongside elderly and less able people to help them stay connected to their gardens — and through them, to their sense of purpose, independence, and wellbeing. Our qualified garden companions offer one-to-one sessions, group gardening, and social prescribing support, bringing both practical help and genuine human companionship.
"Gardening together, sharing ideas, sowing seeds, and taking breaks for tea — it showed me how powerful simple connection can be." — Lou Crouch, Co-founder
If you or someone you love is finding their garden harder to manage, we'd love to help. There's no obligation — just a friendly conversation about what's possible.
Does gardening really improve mental health? Yes. Multiple peer-reviewed studies and meta-analyses confirm that regular gardening reduces anxiety, depression, and stress, and improves overall wellbeing and quality of life.
Who can benefit from companion gardening? Companion gardening is particularly beneficial for older adults, those living with dementia, people with reduced mobility, and anyone who feels isolated or has lost confidence in managing their outdoor space.
What is social prescribing gardening? Social prescribing is when a GP or link worker refers someone to a non-clinical activity — like gardening — to support their mental and physical health. Your Garden Companions works with social prescribers across Cumbria and South West Scotland.
How do I arrange a companion gardening session? Simply contact us by phone or email and we'll have a friendly chat about your garden, your needs, and how we can help.
