Iris sibirica Tropic Night - Hasn't flowered
I hope someone can help
I bought a Iris sibirica Tropic Night last year from a good garden centre and it flowered well. This year it hasn't flowered at all. Its growing well, but it a small plant still. It was planted in partial shade. I have now moved the plant to a full sun position last week) and it seems to be happy enought there.
Will this be enough to help it flower next year? I live in essex with a clay soil it was planted both times with a bought compost. I give it the occasional feed (tomato) but I haven't been consistent with that.
Any advice would be appreciated as i love the flowers, but haven't seen them for a long time now
