Joan uses the example of keen gardener and group patriarch, Graham Smith, 84. He's been a member for 14 years.
"Graham always experiments with varieties, such as trying different strawberries types and using various fertilisers on his plants."
If you ask Graham himself, however, he'll say he attends because he "loves the ladies".
Denys Moss, 71, is studying a course in horticulture. He says the club appeals to men as they have some where they can show off their produce.
"If you grow a gigantic cauliflower, you can bring it along and say 'look what I've grown'," he says.
The club makes him even more enthusiastic about gardening, he says.
Maurice Copsey, 76, and wife Janet used to own a beautiful garden in Britain, which they opened to the public yearly. They no longer have the room for big gardens, but enjoy the club and its outings.
Barwick Harding, 76, says the sales table element will appeal to many men.
Joan would like to encourage more men to join the friendly group. Tauranga South Garden Club meets at Central Baptist Church hall on 13th Ave on the first Wednesday of the month.
