Likely causes
Underwatering
Most likelyHow to tell: The leaf tips turn crispy and brown while the rest of the leaf may look dull or wilted. This happens when the soil dries out completely for too long.
What to do: Water the plant deeply until moisture reaches the root zone. Aim to water every 5 to 10 days depending on the heat and rainfall in your area.
Aphid Damage
PossibleHow to tell: This is less common for this plant, but aphid infestations on new growth can cause the tips of leaves to distort and turn brown. Look for tiny green or black insects clustered on the stems or buds.
What to do: Spray the aphids off with a strong stream of water from your hose. If they persist, use an insecticidal soap to treat the affected areas in the evening.

When to worry
Worry if the browning continues to spread despite regular watering. It is normal for the very tips to brown slightly during extreme heat waves or at the end of the growing season.
Stopping it coming back
Maintain a consistent watering schedule and apply a layer of mulch around the base to keep the roots cool. Keep an eye out for pests during the spring growth flush.
