Check these first
- Check the soil moisture by sticking your finger 2 inches deep.
- Inspect the base of the plant for standing water.
- Look for yellowing on older versus newer leaves.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for more than a few days after watering.
What to do: Stop watering immediately and let the top 3 inches of soil dry out. Ensure your planting site has good drainage and is not sitting in a low spot that collects water.
Nutrient deficiency
PossibleHow to tell: Leaves turn yellow while veins remain green, often starting on older growth. This happens when the soil lacks essential minerals.
What to do: Apply a balanced slow release fertilizer in early spring. Follow the package instructions for your specific soil type to avoid overfeeding.
When to worry
Worry if the yellowing spreads rapidly across the entire vine. A few yellow leaves near the base in late summer is normal as the plant prepares for dormancy.
Stopping it coming back
Maintain a consistent watering schedule of every 7 to 14 days and ensure the soil drains well.
