Calla Lilies Yellowing in NorCal: Deep Water Weekly & Add Bone Meal

Dry Spring = Nutrient & Moisture Stress

Sporadic rain isn't enough. Callas need consistent moisture and feeding.

Deep water once a week (soak root zone).
Sprinkle bone meal around plants per package—slow-release phosphorus for blooms.

Healthy flowers + yellow leaves = plant sacrificing foliage for blooms. Fix water & feed.
