Feverfew · Tanacetum parthenium

Why is my feverfew not flowering?

It is less common for feverfew to skip blooming, as it is a prolific producer of daisy like flowers. Usually, a lack of blooms happens because the plant is not getting enough sunlight to support its energy needs.

Check these first

  1. Observe the amount of daily sunlight reaching the plant.
  2. Check the foliage for signs of excessive, soft green growth.
  3. Assess if the plant is mature enough to bloom.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks tall and stretched out with few buds. It is likely sitting in a spot that is too shady.

    What to do: Move your feverfew to a location that receives at least 6 hours of direct sun daily. If you are growing it indoors, place it directly in a south facing window.

  2. Excessive nitrogen fertilizer

    Possible

    How to tell: The foliage is lush and dark green but there are no flowers. Too much nitrogen encourages leaf growth at the expense of blooms.

    What to do: Stop using high nitrogen fertilizers immediately. Switch to a balanced bloom booster fertilizer with a higher phosphorus content once every 4 weeks during the growing season.

When to worry

Feverfew is a perennial that typically blooms in its first or second year. If it is mid summer and you see no buds, it is time to adjust the light conditions.

Stopping it coming back

Ensure your plant receives consistent full sun and avoid over fertilizing with nitrogen rich products.
