Why does your Pachysandra terminalis have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
In alkaline soils, Pachysandra cannot effectively absorb iron, leading to interveinal chlorosis where leaves turn yellow while veins remain green. This is common in areas with high soil pH or heavy limestone content.
Pachysandra prefers moist but well-drained soil; constant saturation deprives roots of oxygen, leading to yellowing and eventual wilting. This often presents as a more uniform yellowing across the foliage.
A lack of available nitrogen in the soil prevents chlorophyll production, causing older leaves to turn pale yellow before moving to new growth. This is common in depleted woodland soils where organic matter has been exhausted.
While shade-tolerant, Pachysandra requires consistent moisture; prolonged dry spells cause the leaf margins to yellow and eventually turn crisp/brown. This is most common during heatwaves in poorly mulched beds.
