Why is my fairy flax not flowering?

Fairy flax is a sun lover that needs plenty of energy to produce its delicate white blooms. If your plant is sitting in a shady spot, it will focus on growing stems rather than flowers.

Check these first

  1. Observe the amount of direct sun the plant receives each day.
  2. Check if the stems are leaning heavily toward the nearest light source.
  3. Inspect the soil for signs of over fertilization.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks stretched out and pale green instead of a vibrant, compact clump.

    What to do: Move the pot to a location that gets at least 6 to 8 hours of direct sun daily. If you are growing indoors, place it directly in a south facing window.

  2. Excessive nitrogen

    Possible

    How to tell: The plant is lush and very green but shows no signs of buds.

    What to do: Stop using high nitrogen fertilizers. Switch to a balanced, low dose liquid fertilizer once every 4 weeks during the growing season.
