Hi Rosy. I mixed some JI no 2 with my own compost and added some leaf mould, composted turves, organic chicken manure pellets and perlite. I'm afraid I can't tell you in what proportions: I garden like I cook - handfull of this, pinch of that etc . ;) Seriously though it seems perfectly happy in a pot provided you use good compost and water it regularly. I wish you better luck next year. :)
