Why are my Texas bluebonnet tips turning brown?

It is less common for this plant to have brown tips, which usually stems from underwatering or low humidity. Check the soil moisture first to see if the plant is too dry.

Check these first

  1. Check the soil moisture to see if it is bone dry.
  2. Examine the water source for high mineral content.
  3. Look for signs of pests like aphids on the undersides of leaves.

Likely causes

  1. Underwatering

    Most likely

    How to tell: The tips turn crispy and brown while the rest of the leaf feels dry. The soil pulls away from the edges of the pot or cracks in the garden.

    What to do: Water the plant deeply until moisture runs out the bottom or saturates the surrounding soil. Maintain a consistent schedule of watering every 7 to 14 days.

  2. Salt Buildup

    Possible

    How to tell: Brown tips appear even when the soil is moist. This is often caused by using hard water or too much fertilizer.

    What to do: Flush the soil with plenty of fresh water to wash away excess salts. Avoid using softened water, which can contain high levels of sodium.

When to worry

If the browning is limited to just the very tips, it is usually a minor issue. If the brown patches move inward to the center of the leaf, the plant is likely severely dehydrated.

Stopping it coming back

Water consistently and avoid over fertilizing. Use rainwater or filtered water if your tap water is very hard.

Questions people ask

Can I trim the brown tips off?
Yes, you can trim the brown parts with clean scissors. Try to follow the natural shape of the leaf so it looks neat.
Is this a sign of a disease?
Usually not. Brown tips are almost always environmental. If you see white powdery spots, that would be powdery mildew, which is a different issue.
