Grubby Gardener Michael Perry, new product development manager at Thompson & Morgan, said: "I think we raised around £1,000 with our #gardeningselfie day on 3 May, with more than 75 people taking a gardening selfie, and donating to our text number at the same time.
"It was a huge amount of fun, and there has been a huge demand for a calendar, which will be going ahead, and released in time for Christmas."
The grubby gardeners were on a recruitment drive at the RHS Chelsea Flower Show and Perry has hinted that some "key gardening names" have agreed to take part.
Sadly for his fans the world over, gardening national treasure Alan Titchmarsh has not yet volunteered to be one of them.
The naked charity calendar has become a worldwide phenomenon since it was popularised by members of the Rylstone Women's Institute who decided to pose naked undertaking traditional WI pursuits to raise money after group member Angela Baker's husband, John, died from non-Hodgkins lymphoma in 1999.
In 2003 a group of landscape gardeners, aged between 20 and 64, of Bisley-based Graduate Gardeners, produced a naked calendar to raise money for Cotswold Care Hospice, after a colleague’s wife died.
The 16 volunteers posed in gardens they had designed and the calendar’s first print run sold out in less than a week.
