Hedge mustard · Sisymbrium officinale

Why are my hedge mustard leaves getting brown tips?

It is less common for this plant to get brown tips, which usually happens when the soil dries out too much or the air is too dry. Check your soil moisture levels first to see if you have missed a watering cycle.

Check these first

  1. Check if the top inch of soil is completely dry.
  2. Verify your watering schedule is consistent.
  3. Look for signs of heat stress from direct sun exposure.

Likely causes

  1. Inconsistent watering

    Most likely

    How to tell: The tips of the leaves turn dry, crispy, and brown while the rest of the leaf looks dull. This happens when the plant goes too long between waterings.

    What to do: Stick to a schedule of watering every 3 to 7 days. Ensure the soil stays consistently moist but never let it sit in standing water.

  2. Low humidity

    Possible

    How to tell: The leaf tips brown slowly over time even when the soil is moist. This is more common if the plant is kept in a very hot or dry spot.

    What to do: Move the plant to a location with better humidity or group it with other plants. Avoid placing it directly in the path of a heater or air conditioner vent.

When to worry

Worry if the browning is moving inward toward the center of the leaf. It is normal for the very oldest bottom leaves to brown as the plant grows.

Stopping it coming back

Keep the soil evenly moist and avoid letting the plant wilt between waterings.
