Why is my Texas bluebonnet getting leggy?

It is less common for this plant to get leggy, but it usually happens when the plant is not getting enough direct sunlight. Check your light levels first to ensure the plant is getting full sun.

Check these first

  1. Measure how many hours of direct sun the plant gets.
  2. Check if the plant is being shaded by taller plants or structures.
  3. Review your fertilizing schedule.

Likely causes

  1. Insufficient Light

    Possible

    How to tell: The stems are long and thin with large gaps between the leaves as the plant stretches toward a light source.

    What to do: Move the plant to a location that receives full, direct sun for at least 6 to 8 hours a day. If you cannot provide more light, the plant will continue to stretch.

  2. Excessive Fertilizer

    Possible

    How to tell: The plant grows very quickly but the stems are weak and cannot support their own weight.

    What to do: Stop fertilizing your bluebonnets, as they are adapted to lean soils and do not need extra nutrients. Let the plant grow at its natural, slower pace.

When to worry

Worry if the stems are so weak they are falling over and cannot support the flowers. It is normal for the plant to have some height as it prepares to bloom.

Stopping it coming back

Plant your bluebonnets in the sunniest spot in your garden. Avoid adding rich compost or fertilizer to the soil.

Questions people ask

Do bluebonnets need to be pruned to stay bushy?
No, they generally grow in a natural rosette or upright form. Pruning is not necessary and can actually damage the plant.
Will my bluebonnet bloom if it is leggy?
It might still bloom, but the flowers may be smaller or the stems may snap under the weight. Getting more sun is the best way to ensure a strong, healthy bloom.
