Why is my geranium not blooming?

Geraniums are famous for their bright flowers, but they need specific conditions to produce them. Check your light levels first, as these plants crave full sun to bloom.

Check these first

  1. Move the plant to a brighter location.
  2. Check the fertilizer label for the NPK ratio.
  3. Deadhead old blooms to encourage new growth.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks tall and stretched out with large gaps between the leaves.

    What to do: Move the plant to a spot where it receives at least 6 to 8 hours of direct sunlight daily. If you are growing indoors, a south facing window is usually best.

  2. Too much nitrogen

    Possible

    How to tell: The plant has lush, dark green foliage but absolutely no flower buds.

    What to do: Switch to a fertilizer labeled for blooming plants that is higher in phosphorus and lower in nitrogen. Apply it every 2 to 4 weeks during the growing season.

When to worry

If you have provided full sun and proper food for several weeks without results, the plant might be too young or stressed. It is normal for geraniums to take a break from blooming during the heat of midsummer.

Stopping it coming back

Keep your geranium in a sunny spot and remove faded flowers regularly to signal the plant to put energy into new buds.
