Alliums not blooming
I planted giant alliums several 4 years ago. I had very nice blooms for 2 years. Since then they have had no blooms. For the last 2 years they have been producing a lot of healthy looking foliage but never bloom. They are in sun. Any ideas?
Are they planted deep enough? If they are shallow, they split and form a lot of bulbs but not a lot of flowers. A bit of a feed once they start flowering builds up the bulbs faster.
Thanks! I think I'll dig them up and replant (making sure they are deep enough), divide, and see what happens next year.
