Weldon,
I have lifted/divided crinum only once, and that was in early November during a plant rescue. They survived (did you know that even if you cut a bulb, as long as the root wad at the bottom is intact, the bulb will survive? I didn't, but sure was glad to find that little fact out!).
I was told that the larger bulbs would bloom the next year, having stored enough energy to do so, but the smaller bulbs might not bloom for a year or two.
Good luck with your lifting and dividing. Probably someone with a lot more knowledge will answer your query. Personally, I'd go with what the next guy says!

I've lifted and move crinums all most year round and have had no problems. Have given some to my sisters in Bonham on the OK border and in Beaumont on the coast. They've had no problems either. I'd guess they are really tough.

The main thing to remember is they..or at least mine...are DEEP deep bulbs. Mine have been in the same spot along a drive for at least 60 years. I'm in deep sand in East Texas.

Weldon, I am in Springtown. If you aren't too far away, I'd be glad to do the labor part and divide and replant the bulbs for you in return for a pup or two. Billy

Weldon, you've got mail............

Weldon - good to see you post. The crinums you gave me are doing wonderfully. I had bloom all summer. What a wonderful plant. And to think you had to practically force me to take them - THANKS!!! (FOR THE POTS THAT IS) ;-)

I'd wait till spring that far north, simply because it's about to turn cold, ya'll may even be having a freeze now for all I know, and the roots are going to be exposed with the soil churned up. Or at least mulch them heavily. And no, you don't need to trim up the leaves (I forgot on the amaryllis forum), the plant will probably lose some, they will turn yellow & you can cut them off then.
Tally HO!

I've moved crinums at every time of year, & I've also cut into the bulbs by accident, &, as marlin says, most of them have recovered beautifully.

Fairview (Frank) *really* has crinum-moving down to an art or a science, but I can't remember everything he told me.

seems like it involves an ergonomic spade with a flexible handle (nylon? fiberglass?) that you use to tranch around the whole area, & then you use your implement of choice (fork, shovel, etc) as a sort of lever to pry the bulbs loose.

Thanks, everyone. You're a great help! Billy, you're on!
Check your mail. Justintx (I'll not reveal your ID.) glad you
liked the "Pots". Sylvia, the pink crinum is one that I got from you. Got the mail, Carrie. Folks, don't forget to come by in June and see the daylilies.

Weldon

Hello ! I was reading your post because I also have crinums that need to be moved. But what interested me more was your last comment about seeing the dayliles in June. I was curious as to what part of Tx you're in. I'd love to see the daylilies if they put on a show ! Is anyone welcome ?

thank you !
