I brought 2 alliums in pots last year. Whilst one has flowered this year the other hasn't. I was told when i brought them that the routes like to be kept tight in a pot with little room. However I have just removed the none flowering one from the pot and it is completely pot bound.
Would i do best repoting it in a larger container or striaght in to the ground. Can the bulb be spilt in to 2? It would appear that the bulb is fairly mature as it has alot of old folige at the top of the bulb? As you can see I have no experience off growing alliums and any advice would be appriciated.
