Hello everyone! I have a friend who recently moved to Paris (3 months). She started her little flower garden, and encountered some problems such as plants needing acidifier and some plants need 10-10-10 fertilizer. So very sadly, she's new in the area and couldn't find a gardening supply store in Paris that carries any product she was familiar with or any equivalent products I recommended to her. I would truly appreciate any information on where to buy gardening supplies in Paris. Thank you very much, and happy gardening! K.
