Not enough light
An African violet that stretches its leaves upward and refuses to bloom is almost always under-lit.
Diagnosis
Not enough light
What's happening
Blooming takes more energy than foliage, so light is the first thing a violet cuts back on when it's short. In dim conditions the leaf stalks elongate and reach up toward the window instead of sitting flat in a tidy rosette, and the plant simply stops setting buds. African violets need consistent bright, indirect light to flower well.
How to fix it
Move the plant to a brighter spot with steady, bright indirect light — an east or north window is ideal, or a few feet back from a curtained south or west one. If your home is genuinely dim, a grow light is the reliable fix and is what many growers use to keep violets blooming year-round; aim for 10–12 hours a day positioned a foot or so above the plant. New growth should come in flatter and more compact, with buds following.
What fixes it

If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
