Fixing Yellowing Pygmy Date Palm in Arizona Desert

Overwatering Is the Likely Culprit

A Phoenix gardener's newly planted pygmy date palm yellows despite daily 30-minute bubbler irrigation, fertilizer spikes, and vitamin B.

Expert Correction

Nick says even in arid climates, pygmy dates need far less water—once a week is sufficient. Fertilizer spikes only feed a small root zone; switch to granular palm fertilizer spread evenly from the drip line inward. Reduce watering and change fertilizer method to stop yellowing.

Key Adjustments

• Water weekly, not daily.
• Use granular palm fertilizer, not spikes.
• Ensure good drainage.
