Sun spurge · Euphorbia helioscopia

Why are my Sun spurge leaves getting brown tips?

It is less common for this plant to have brown tips, which usually happens due to low humidity or mineral buildup in the soil. Check your water quality first to see if it contains too many salts or minerals.

Check these first

  1. Check if you are using tap water with high mineral content.
  2. Observe if the air in your home is very dry.
  3. Look for salt crusts on the soil surface.

Likely causes

  1. Mineral Buildup

    Possible

    How to tell: The tips turn brown and crispy while the rest of the leaf remains green.

    What to do: Flush the soil with distilled or filtered water to wash away excess salts. Avoid using tap water that is high in chlorine or minerals.

  2. Low Humidity

    Possible

    How to tell: The leaf edges dry out and turn brown, especially in very dry indoor environments.

    What to do: Group your plants together to create a more humid microclimate. You can also place a tray of water and pebbles near the plant to increase local moisture.

When to worry

If the browning spreads rapidly to the center of the leaves, it may indicate a deeper issue like root stress. It is normal for the very oldest leaves at the base to brown and drop as the plant grows.

Stopping it coming back

Use filtered water and keep the plant away from direct air conditioning or heating vents.
