The study of 2,000 Brits found this blossoming trend is especially popular among young adults.
Six in 10 18-to-34 year-olds (58 per cent) have been growing fruit and veg at home over the past year - more than any other age group.
Wanting to save money (32 per cent), help the environment (23 per cent), be more sustainable (28 per cent) and eat more fruit and veg (15 per cent) are behind the trend.
And the most popular items to grow are tomatoes, herbs, and strawberries, followed by carrots and runner beans.
However, the study by Linda McCartney Foods [https://lindamccartneyfoods.co.uk/], which turns 30 this year, found 70 per cent of adults want to grow even more produce at home but are unable to.
The biggest barrier is lack of space (27 per cent), with half of adults - including 66 per cent of 18-to-34 year-olds - wishing they had a bigger garden area.
Another 13 per cent simply wish they had a garden - with young adults again suffering more than other age groups in this respect - 23 per cent compared to nine per cent.
In order to help people like these, the vegetarian food company has announced its ‘Grow Your Own with Linda’s’ initiative to coincide with National Vegetarian Week and its 30th anniversary.
The scheme will see ‘growing spaces’ built in urban areas throughout the country, while a Grow Your Own Guide will be available on the Linda McCartney Foods website in the coming weeks.
Paul McCartney said: “We’re so pleased to bring this initiative to people across the UK and continue the legacy of kindness that Linda set out with for her veggie food company, 30 years ago.
“Linda aimed to show that being kind didn’t mean having to compromise on eating delicious food.
"Through this project, we hope we can empower more people across the UK to try growing, and eating, their own.
“Dig in and have fun.”
The study also found two thirds of adults enjoy growing so much they would happily live off their own home-grown foods if they could.
Home growers already enjoy an average of three meals a week containing produce they’ve cultivated themselves.
It also emerged 72 per cent believe growing your own food produce is good for mental health, and 68 per cent agree it also encourages you to have a better diet.
Other benefits to home-grown food include giving you a reason to get outside (52 per cent) and being more ethical than some mass produced foods (29 per cent).
And notably, 48 per cent think home-grown tastes better than items purchased from shops.
However, the study carried out through OnePoll found two thirds (66 per cent) would like to have greater fruit and veg growing knowledge - with those aged 18 to 34 especially keen (77 per cent).
Further to this, 32 per cent of all adults have little in the way of greenspace where they live, while 37 per cent often struggle to find somewhere they can go to switch off.
Expert grower and gardener, Diarmuid Gavin, who is offering his expertise on the project, said: “This has been such a great initiative to be involved with especially at a moment when the outdoors and nature has become even more precious in lockdown.
“I hope the Grow Your Own Guide can be an inspiration for people in flats, tower blocks and without much outdoor space to see just how much they can grow with their own hands and a few recycled containers.”
Almost half of Brits (46 per cent) revealed their passion for growing produce at home has increased during the last 12 months.
And while the most popular place to grow produce is the garden (65 per cent), other notable locations include the kitchen (27 per cent) and the bathroom (11 per cent).
One in 10 (11 per cent) have also turned their balconies into an area for cultivating fruit, veg and herbs.
