early hair-grass · Aira praecox

Why is my Aira praecox not flowering?

It is less common for this grass to fail to flower if it is healthy, as it naturally produces delicate panicles in the spring and summer. This plant needs plenty of direct sun to bloom properly.

Check these first

  1. Observe how many hours of direct sun it gets.
  2. Check if the plant is crowded by other pots.
  3. Review your recent fertilizing habits.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks thin and lacks the energy to produce flower stalks.

    What to do: Move your plant to a spot where it gets full, direct sun for at least 6 to 8 hours a day. This is the most important factor for blooming.

  2. Excessive fertilizer

    Possible

    How to tell: The plant is very green and leafy but shows no signs of flower stalks.

    What to do: Stop fertilizing for the season. This grass prefers poorer soil and too much food encourages leaves over flowers.

When to worry

If the plant is not blooming by mid summer, it likely did not get enough light during the spring. It is normal for young plants to skip flowering in their first year.

Stopping it coming back

Ensure the plant stays in a bright, sunny location throughout the entire growing season.

Questions people ask

Will it bloom indoors?
It is very difficult to get this grass to bloom indoors because it requires intense, direct sunlight. It will perform much better outdoors in full sun.
Do I need to prune it to make it flower?
No, pruning is not required for flowering. Just let it grow naturally in a sunny spot.
