The reasons begonia × semperflorens-cultorum 'cocktail vodka' isn't blooming

Almost every non-blooming begonia × semperflorens-cultorum 'cocktail vodka' traces back to one of these, roughly in order of how common they are:

Too little light — the number-one reason by far; a plant that "survives" in a dim corner has no energy spare to flower.
It is grown purely as a foliage plant in deep shade, where flowering is not possible.
Wrong feed: too much nitrogen gives lush leaves and few or no flowers — it needs a balanced or bloom-leaning feed.
It is too young, stressed, or recovering from root problems to put energy into flowers.
Inconsistent watering or cold draughts knock it out of flowering mode.

Keeping begonia × semperflorens-cultorum 'cocktail vodka' in a dim "low-light tolerant" spot and expecting flowers. It survives there but only blooms with genuinely bright light.

The fix — how to get begonia × semperflorens-cultorum 'cocktail vodka' to flower

Move it into real light. Give begonia × semperflorens-cultorum 'cocktail vodka' bright, indirect light — a north or east window, or 25-30 cm under a grow light. This change alone fixes most non-blooming cases.
Keep it warm and steady. Hold steady warmth, avoid cold draughts, and keep watering consistent so it stays in flowering mode.
Feed for flowers. Use a balanced or higher-phosphorus feed at half strength regularly in growth — ease off high-nitrogen leaf feeds.
Let it settle. Fix any root issues and give a young or recently moved plant time to establish before expecting flowers.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for begonia × semperflorens-cultorum 'cocktail vodka' and get the feeding right with the begonia × semperflorens-cultorum 'cocktail vodka' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.
