I’ve had my Albuca spiralis not go dormant. It doesn’t really matter, if you keep them watered and happy it’ll keep throwing out leaves and flowers. I pushed mine into dormancy during the summer by putting them in the shade and no water. They’re winter growers.

Tbh I don’t know when the best time to repot is, but I’ve done it with or without leaves. Ime is doesn’t really matter, it’s probably easier when dormant. If you do repot now hold off on any water for at least a week. They’ve got big juicy roots and you don’t want to cause any rot by watering too soon after a repot. If you repot during dormancy than obviously no water till it sprouts leaves.

It’s prob a good idea to expose the bulb maybe a third this repot, then a third next repot, and so on. I would think exposing too much too fast could cause a problem because the bulb that’s below the surface is like an onion without the skin.
