Why are my sweet marjoram leaf tips turning brown?

This is less common for this plant, and usually happens due to inconsistent watering or salt buildup in the soil. Check your watering habits to ensure the soil stays consistently moist but not soggy.

Check these first

  1. Check if the soil has been allowed to dry out completely for too long.
  2. Look for white crusty deposits on the soil surface.
  3. Review your recent fertilizing schedule.

Likely causes

  1. Inconsistent Watering

    Most likely

    How to tell: The tips turn brown and crispy while the rest of the leaf remains green. This happens when the plant goes through cycles of being too dry and then too wet.

    What to do: Establish a regular routine where you check the soil every 3 to 7 days. Water consistently as soon as the top inch of soil feels dry.

  2. Fertilizer Burn

    Possible

    How to tell: Brown tips appear shortly after you have applied fertilizer. The leaves may also look slightly scorched or curled.

    What to do: Flush the soil with plenty of plain water to wash out excess salts. Avoid fertilizing for at least 4 to 6 weeks to let the plant recover.
