Why are my wisteria leaves turning yellow?

Yellowing leaves are less common for wisteria and usually point to issues with soil drainage or nutrient uptake. Check your soil moisture levels first to see if the roots are sitting in standing water.

Check these first

  1. Feel the soil to see if it is soggy.
  2. Check the soil pH with a home testing kit.
  3. Inspect the base of the vine for signs of borer damage.

Likely causes

  1. Overwatering

    Possible

    How to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil remains wet for more than 10 days after watering.

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

  2. Iron Chlorosis

    Possible

    How to tell: The veins of the leaves stay green while the rest of the leaf turns yellow. This happens when the soil pH is too high for the plant to absorb iron.

    What to do: Test your soil pH and aim for a range between 6.0 and 7.0. Apply a chelated iron supplement to the soil or foliage to correct the deficiency.

When to worry

It is normal for older leaves to yellow and drop in late autumn. Worry if new growth turns yellow or the entire vine looks pale.

Stopping it coming back

Maintain consistent soil moisture without saturation and keep the soil pH slightly acidic.

Questions people ask

Will yellow leaves turn green again?
No, once a leaf has turned yellow due to stress or deficiency, it will not recover. It is best to let the plant shed it naturally.
Can I fertilize my yellowing wisteria?
Only fertilize if you have confirmed a nutrient deficiency. Adding fertilizer to a stressed or overwatered plant can make the damage worse.
