Mother of Thyme · Thymus praecox

Why is my Mother of Thyme not flowering?

It is less common for this plant to fail to bloom when grown outdoors in the right spot, as it usually flowers in late spring to early summer. The most frequent cause for a lack of blooms is insufficient sunlight.

Check these first

  1. Observe the amount of direct sun your plant receives throughout the day.
  2. Check for any nearby plants that might be shading your thyme.
  3. Inspect the soil for signs of over fertilization.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The plant looks stretched out or thin and fails to produce the dense mat of flowers expected in summer.

    What to do: Move your thyme to a location that receives at least 6 to 8 hours of direct sun every day. If your garden is too shaded, consider pruning back nearby shrubs to open up the canopy.

  2. Excessive Nitrogen

    Possible

    How to tell: The plant has lush, dark green foliage but no flower buds appear during the peak blooming season.

    What to do: Stop using any high nitrogen fertilizers immediately. Thyme prefers poor, rocky soil and does not need extra food to bloom well.

When to worry

If your plant is in full sun and still not blooming after two full seasons, it may be an older plant that needs dividing. It is normal for young plants to focus on root and foliage growth before their first bloom cycle.

Stopping it coming back

Keep your thyme in a sunny, well drained spot and avoid adding compost or fertilizer to the soil.
