Basil · Ocimum basilicum

Why are my basil plant's leaf tips turning brown?

It is less common for basil to get brown tips, which usually happens when the plant is struggling with inconsistent moisture or salt buildup in the soil. Check your watering schedule first to see if the soil is drying out too much between waterings.

Check these first

  1. Check the moisture of the top inch of soil with your finger.
  2. Inspect the soil surface for white crusty salt deposits.
  3. Verify your watering frequency is every 1 to 3 days.

Likely causes

  1. Inconsistent Watering

    Most likely

    How to tell: The soil feels bone dry and the leaves may look slightly wilted along with the brown edges.

    What to do: Water your basil whenever the top inch of soil feels dry. Aim to keep the soil consistently moist but never soggy.

  2. Fertilizer Burn

    Possible

    How to tell: Brown tips appear shortly after you have applied a liquid fertilizer.

    What to do: Flush the soil with plenty of plain water to wash out excess salts. Wait 4 to 6 weeks before fertilizing again with a balanced, diluted formula.

When to worry

Worry if the browning spreads rapidly to the center of the leaves. A few tiny brown spots on older leaves are usually just signs of aging.

Stopping it coming back

Maintain a steady watering routine and avoid over fertilizing your basil.
