- Look for signs of pests on the undersides of the leaves.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil remains soggy for days after watering.
What to do: Stop watering immediately and let the top 3 inches of soil dry out. Ensure the planting site has good drainage so water does not pool around the roots.
Nutrient deficiency
PossibleHow to tell: Older leaves turn yellow while the veins remain green. This often happens in poor, sandy soil.
What to do: Apply a balanced, slow release fertilizer in early spring. Spread it around the base of the plant and water it in well.
