So I just discovered that my potted amaryllis -- a grow kit bulb I picked up at Lowe's in 2020 -- is starting a new flower stalk! Yippee! This will be the third one it's grown, so I must be doing something right.
My question is in regards to repotting. In fall 2021 when the leaves died back, I pulled out the bulb, and replanted it in new soil a few months later -- as the care guides tell you to do. But this fall the leaves never died back, so I still haven't done that. I'm wondering whether I should do that now, or if I should wait until the flowering is done. Recommendations?

Given the fact, it looks happy and healthy, I would leave it alone through spring and summer. Perhaps it just decided not to go dormant this winter. There are cultivars that tend to keep their leaves all winter, but in this case it probably is more of a fluke of nature. Congratulations on getting the third scape.

@bsharf — a gardener in another forum recommended the same. I'm going to give a dose of Osmocote and let it be!

@bsharf -- what cultivars do you know of that keep their leaves? This one is a 'Tinkerbell'. It just started growing a couple of new leaves, too, without any change in the old ones.
@pixie62560, @bumplbea, @SuperHappyCamper -- I see that you guys have this cultivar. Has yours developed an 'evergreen' habit too?

Good question, I can't give you a specific list just off the top of my head, It may be due to individual variations and cultural practices more than particular cultivars. According to Veronica Read, 'Hippeastrum, the Gardener's Amaryllis' published by the RHS, all Hippeastrum are evergreen. Common cultural practices (decreasing day length, decreasing temperature and decreasing soil moisture) force dormancy both to ship dormant bulbs and to time out blooming. Blooming is triggered by increasing day length, increasing temperature, and increasing moisture, whether or not the bulbs have previously lost their leaves. I have heard antidotal accounts of some of the small flowered cultivars and some of the cybister forms tending to be evergreen. This is a fascinating subject and I would like to hear others' experiences.
