Check these first
- Stick your finger 3 inches into the soil to check for dampness.
- Look for signs of standing water near the root zone.
- Check if the yellowing is on older leaves or new growth.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and may feel soft or limp. The soil around the base stays soggy for days after watering.
What to do: Stop watering immediately and let the top 3 inches of soil dry out. Ensure the area has proper drainage and is not sitting in a low spot where water pools.
Nutrient Deficiency
PossibleHow to tell: The yellowing happens evenly across the leaves while the veins remain green. This often happens in very alkaline or poor soils.
What to do: Apply a balanced, slow release fertilizer in early spring. If the soil pH is very high, consider adding organic compost to improve nutrient availability.

When to worry
A few yellow leaves in the fall are normal as the plant prepares for winter. Worry if the yellowing is rapid and affects the whole plant during the growing season.
Stopping it coming back
Stick to a consistent watering schedule of every 7 to 14 days and avoid over-fertilizing.
