No flower stems on my potted Allium bulbs?


Hello fellow plant lovers,
I potted Allium Miami and Purple Rain bulbs last October with a view to plugging gaps in borders with them this spring. They were planted 3/4 times the depth of the bulb in gritty compost with a grit topping, 4 bulbs to a large 10" pot or singly in 6" pots. I haven’t fed or watered them much since. They grew well initially. Now they are doing that Allium foliage dying thing, but only two out of twenty have developed flowering stems. Where have I gone wrong? Am I being impatient? What should I do with them now? (Polite suggestions only.) Many thanks, Johnny

it sounds like they have suffered from a lack of water and food. I purposefully impoverish my garlic cloves using a similar but not quite so harsh method and this gives me bigger garlic bulbs the following year.
I wouldn’t recommend it for ornamentals though.
