My Dad has loved playing bowls since before I was born. He competes in league fixtures with his Crown Bowling team, and jumps into the occasional tournament too. When he's not playing, he's peering across the green, making marks on the score-sheet.
Or else he turns around and does a little bit of gardening.
The entire bowling team have co-opted a long, otherwise unruly, patch of land between the lawn and the fence. They've transformed it into an ad-hoc allotment. Whoever is playing that day pauses between turns to do some weeding, or grabs the hose-pipe to water the vegetables.
What started with one of them planting a few surplus potato seeds has now turned into a veritable cornucopia of groceries.
For such a small patch, it's surprisingly fertile. During certain seasons, I'm forever opening the door to find a random man handing me a bursting carrier bag of beans, or sprouts, or marrows. He will be one of the bowlers. This is my Dad's share of whatever just matured enough to harvest.
There's too much for us! Even with several bags frozen for future use, we end up giving away clutches of vegetables to whoever knocks the door.
Yet no one person is doing too much work, nor paying too much outlay. Most of the seeds have been donated, or stored from last time, or brought in from someone's own garden. They just all do a little bit and everyone reaps the benefits.
Have you got a communal strip of land like that, and a group of friends to keep it tended? How about a corner of your garden? If each of you just gave up a few square feet, then parceled out the growing between you, then you could swop and exchange the produce.
Even if you haven't access to land for turning into an allotment, many vegetables grow in pots. Just each join forces to transform windowsills, window-baskets, balconies and rooftops into mini-allotments, and none of you will need to buy vegetables all season long.
