Emmaus Brighton & Hove relies on donations of unwanted items to sell in its six secondhand shops.
These social enterprises generate the funds needed to provide a safe home, nutritious food, meaningful work, training and individual support for up to 57 people who have experienced homelessness – known as companions.
Throughout the week, Emmaus Brighton & Hove will welcome donations of garden furniture, tools, pots, books and bric-a-brac to fill its popular plant shop, The Greenhouse.
Alongside its social enterprises, the charity has its own community garden and polytunnel used to propagate donated plants from customers.
This spring, a group of nine companions have also started their own allotments to grow fresh crops on site.
One of those companions is Sian, who experienced homelessness on the streets of Worthing before she moved into Emmaus Brighton & Hove.
"In my allotment, I'm growing two varieties of potatoes, onions, radishes and runner beans.
"It's great to get outside in the fresh air, and so good that we'll be able to put our own homegrown food on the table for the community."
Joel Lewis, Business Manager at Emmaus Brighton & Hove, adds:
"We are very lucky to have such amazing gardens and grounds here at Emmaus, and we've had an excellent uptake of companions wanting to get involved in the community food garden.
"I think between all of the plots, we will see around 18 different varieties of vegetables grown this year."
