Why are my Viper's bugloss leaves turning yellow?

It is less common for this plant to have yellow leaves, which usually happens due to overwatering or poor drainage. Check the soil moisture levels first to see if the roots are sitting in water.

Check these first

  1. Stick your finger 2 inches into the soil to check for dampness.
  2. Inspect the drainage holes to ensure they are not blocked.
  3. Check the base of the plant for signs of rot.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The lower leaves turn yellow and feel soft or mushy to the touch.

    What to do: Let the soil dry out completely for 7 to 14 days. Ensure your pot has drainage holes and never let the plant sit in a saucer of standing water.

  2. Nutrient Deficiency

    Possible

    How to tell: The leaves turn a pale, sickly yellow while the veins remain green.

    What to do: Apply a balanced liquid fertilizer diluted to half strength once in the spring. Do not overfeed, as this plant prefers lean soil.

When to worry

A single yellow leaf at the very base is often just natural aging. If multiple leaves turn yellow at once, you have a watering issue to address.

Stopping it coming back

Stick to the 7 to 14 day watering rhythm and only water when the top few inches of soil are dry.
