|Do Allium Bulbs need to be dug up each yr. and replanted? Do the stems need to die down before cutting them off? This is my first yr. and I am not familiar with how to care for the bulbs or the plants. Thanks much

|Alliums are considered hardy bulbs and so they do not need to be dug each year. They are planted in the fall and left in place to bloom each spring. After blooming the foliage should be left to grow and mature and eventually fade. Once it has browned it may be removed. The flowers may be removed when they fade. The reason for this is that the foliage supplies energy to help the bulb regain its strength so it can bloom again. Removing the blooms prevents the bulb from using energy to set seed rather than for blooming.
