Check these first

  1. Measure the hours of direct sunlight the plant receives.
  2. Check if the plant is being shaded by taller shrubs or trees.
  3. Observe if the plant is growing too tall and thin.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks tall and stretched out with few or no buds. It is likely not getting the full sun it craves.

    What to do: Move the plant to a location that receives at least 6 to 8 hours of direct sunlight daily. If it is in a pot, shift it to the sunniest spot in your garden.

  2. Excessive nitrogen

    Possible

    How to tell: The plant has lush, dark green foliage but no flowers. This often happens if the soil is too rich in nitrogen.

    What to do: Stop using high nitrogen fertilizers. Switch to a balanced fertilizer or just let the plant grow in standard garden soil.

When to worry

If the plant is mature and still shows no signs of buds by mid summer, it is likely not getting enough light. It is normal for young plants to skip flowering in their first year.

Stopping it coming back

Plant in a spot that gets full sun all day long. Avoid over fertilizing the soil.
