i know i posted this question before but i never really got an answer. why would allium bulbs that flowered 2 years in a row not flower this year? does the mother bulb split? should i expect flowers in subsequent years (maybe what has grown is from baby bulbs and will flower in following years)? should i give up on them and just replant new ones in the fall? the alliums i am inquiring about are gladiators. also, how and when do i dig up and move allium bulbs from one place to another. thanks again for any information. it is greately appreciated.
