Do this and your geraniums will be able to bloom almost continuously for over a year.

That kind of claim (“almost continuous blooms for over a year”) is a classic gardening exaggeration. No single trick will keep geraniums flowering nonstop for that long. But there are proven practices that can make them bloom heavily and repeatedly for many months.

Here’s what actually works for healthy, long-lasting flowering geraniums (Geranium, also called Pelargoniums in many gardens):

1. Deadhead spent flowers regularly

Remove faded blooms right away. This tells the plant to produce new buds instead of seeds.

2. Give them full sun (very important)

Geraniums need 6–8 hours of sunlight daily. Less light = fewer flowers and more leaves.

3. Don’t overwater

They prefer slightly dry soil between watering. Constantly wet soil leads to weak growth and fewer blooms.

4. Use a low-nitrogen fertilizer

Too much nitrogen makes leafy plants with few flowers. A “bloom booster” fertilizer helps encourage flowering.

5. Prune lightly and regularly

Pinching or trimming stems encourages branching, which means more flower sites.

The real expectation

Even with perfect care, geraniums:

Bloom strongest in warm seasons
May slow down in extreme heat or cold
Usually don’t bloom “nonstop for a year” unless grown in ideal controlled conditions

If you want, I can give you a simple monthly care schedule that keeps geraniums flowering as long as realistically possible (especially for balcony or garden pots).
