They bloomed, are spectacular but soooo tall. These are along the edge of my front yard and because of their height, looks kinda weird. They are about 3 years old. Can I move them in fall this year? Will it still survive? I didnt move them in the past in fear that they will die. Dont want to lose them at all. See how lovely the flowers are : ( photo / image / picture from Tina's Garden )
Wait until the greenery has turned yellow, then cut it off and move them. They can be temperamental and not bloom next year or not as much as they have in the past but they should do fine.
Do as toni says AND put bone meal and bulb booster on them when you move them. If by chance you happen to damage a bulb, don't replant it that way. get some garden sulfur at the garden center and dust them first.
Looks Oriental not Asiatic. Don't they have a nice fragrance??? Anyway, they should transplant well. They should be planted kinda deep in the ground, right? Maybe next year they won't grow that big but they will get better.
