Can I save a branch with leaf scorch?

Unfortunately, leaf scorch is a systemic bacterial infection that is difficult to cure. Pruning the affected parts is the best way to slow it down.

Are these spots harmful to me?

The spots themselves are not, but remember that all parts of the oleander plant are toxic if ingested. Always wear gloves when pruning.

Why are there spots on my oleander leaves? Causes and fixes

Check these first

Inspect the undersides of leaves for insects.
Check if the spots are spreading from the tips inward.
Assess the humidity levels in your garden area.

Likely causes

Oleander leaf scorch
Possible
How to tell: Leaves turn brown and die back from the tips, often looking like they were burned. This bacterial infection spreads through the plant's vascular system.
What to do: Prune away the affected branches immediately, cutting back to healthy wood. Sterilize your pruning shears with rubbing alcohol between every single cut to prevent spreading the bacteria.
Fungal leaf spot
Possible
How to tell: Small, circular brown or black spots appear on the foliage, often with a yellow halo. This happens when the leaves stay wet for too long.
What to do: Improve air circulation around the plant by thinning out dense branches. Avoid overhead watering and ensure the plant is in a spot with full, direct sun.

The list above covers the usual causes. Pocket Botanist looks at a photo of your actual plant and tells you the likely cause, how serious it is, and what to try first. Identification and a health check are free.

When to worry

If the entire branch is turning brown and brittle, it is likely leaf scorch and requires aggressive pruning. Small, isolated spots are usually just cosmetic and not a major threat.

Stopping it coming back

Keep the foliage dry by watering at the base of the plant rather than over the leaves. Ensure your oleander gets plenty of direct sunlight to dry off quickly after rain.
