False indigo bush · Amorpha fruticosa

Why are my False indigo bush leaves turning yellow?

It is less common for this plant to have yellow leaves, and it usually happens when the soil stays too wet for too long. Check the soil moisture levels first to see if the roots are sitting in water.

Check these first

  1. Check the soil moisture by sticking your finger 3 inches deep.
  2. Inspect the base of the plant for standing water.
  3. Look for signs of nutrient deficiency in the soil.

Likely causes

  1. Overwatering

    Possible

    How to tell: The leaves turn yellow starting from the bottom of the plant and feel soft or mushy. The soil remains damp to the touch for more than 5 days.

    What to do: Stop watering immediately and let the top 3 inches of soil dry out completely. Ensure your planting site has good drainage and is not in a low spot that collects water.

  2. Nutrient deficiency

    Possible

    How to tell: The leaves turn a pale yellow while the veins remain green. This often happens in poor, sandy soils where nutrients wash away quickly.

    What to do: Apply a balanced, slow release fertilizer in early spring. Add a layer of organic compost around the base of the shrub to improve soil quality.

When to worry

Worry if the yellowing spreads rapidly across the entire bush. It is normal for a few older leaves near the base to yellow and drop in late summer.

Stopping it coming back

Plant in well draining soil and avoid overwatering once the shrub is established after the first year.
