I have seral crinums scattered around. They may have made sense to the PO, but I want to move some. Will I destroy them if I do it now? Should I split up the clumps, or just dig it up and move it?
You can move a crinum any time of the year except when expecting a freeze. The plants may be difficult to dig up though as some mature crinums have very large bulbs with extensive root systems. Don't worry about damaging the roots though as they will regrow just like any other type of bulb.
Just make sure to dig deep enough to get the bottom 'plate' of the bulb(the part the roots come out of); they won't grow w/o it...
I just moved mine and they adjusted, no problem. I dug a deep enough hole to unearth them pretty intact. I took the opportunity to remove some babies, then put them in their new home. No wilting or signs of stress. I did water with Miracle Grow right after. I moved two medium sized Queen Emmas. I hear Ellen Bosenquat does not transplant easily, though.
Ellen B. transplant just fine. The problem is getting the mature plants out of the ground first! They can have soccer ball sized bulbs with the thickest root system I've ever seen. I've heard of people having to bring in backhoes in order to get mature clumps of Ellen Bosenquets out of the ground. I know that I can't budge mom's established patch of mature EBs!
