Likely causes
Insufficient Light
Most likelyHow to tell: The plant looks healthy but produces only leaves with no flower buds. It may also start stretching toward the nearest light source.
What to do: Move your geranium to a spot that receives at least 6 to 8 hours of direct sun every day. If you are growing it indoors, place it in your sunniest south facing window.
Excessive Nitrogen Fertilizer
Most likelyHow to tell: You see lush, dark green foliage but absolutely no flowers. This happens when the plant is fed a fertilizer too high in nitrogen.
What to do: Switch to a balanced fertilizer or one labeled for blooming plants that is higher in phosphorus. Apply it at half strength every 2 to 4 weeks during the active growing season.

When to worry
It is normal for geraniums to take a short break from blooming during extreme heat or after a heavy flush of flowers. Worry if the plant has been in full sun for months without a single bud.
Stopping it coming back
Keep your geranium in full sun and use a fertilizer specifically formulated to encourage flower production.

Questions people ask
- Should I deadhead my geranium to help it bloom?
- Yes, removing spent flower stalks encourages the plant to put energy into creating new buds rather than seeds. Simply pinch or snip the old stem off at the base.
- Will my geranium bloom indoors?
- It can, but it needs very bright, direct light to do so. Most indoor spots do not provide enough intensity for consistent flowering.
