Why did my alliums not come up this year?Updated 21 days ago

Alliums will usually flower year after year however they can fail to thrive if they have been planted too deep, too shallow, in boggy soil and in a position without sun. If your alliums have multiplied since the first year, the new bulbs will be immature and will only produce leaves for their first few years. Some varieties (typically the larger types) have relatively short lifespans and the bulb can die after the first or second flowering season.
