Likely causes
Underwatering
Most likelyHow to tell: The tips of the leaves turn crispy and brown while the rest of the foliage looks dull. This occurs when the plant does not get enough water during its spring growth spurt.
What to do: Water the plant deeply every 7 to 14 days during the spring. Ensure the water reaches the root zone rather than just wetting the surface.
Heat stress
PossibleHow to tell: The tips brown during unusually hot and dry spells in late spring. The leaves may also appear slightly curled or wilted.
What to do: Apply a layer of mulch around the base to keep the roots cool. Provide extra water during heat waves to help the plant cope.

When to worry
Worry if the browning moves down the leaf toward the base, as this indicates a more systemic issue. Minor tip browning is often just a reaction to dry air or brief water stress.
Stopping it coming back
Maintain a consistent watering schedule throughout the spring and apply mulch to retain soil moisture.

Questions people ask
- Will the brown tips turn green again?
- No, the brown parts are dead tissue and will not recover. You can snip them off with clean scissors for aesthetic reasons.
- Does full sun cause brown tips?
- Foxtail lilies love full sun, but they need adequate moisture to support that growth. If they are dry, the sun will cause the tips to brown faster.
