Fruitless Mulberry Scorch in High Desert: Overwatering Diagnosis and Correction

The Real Problem: Too Much Water

Daily 2.5-gallon watering on newly planted mulberries in hot, windy high desert has leached nutrients and created anaerobic soil. Symptoms (chlorophyll loss, not true scorch) confirm root dysfunction from waterlogging.

Corrected Watering Schedule

1. Stop watering for 5 days.
2. Then water every 3rd day with 1 inch of water (use a pan under sprinkler to measure).
3. Skip if rain occurs.

Additional Steps

• No fertilizer until spring. Roots need to recover, not push growth.
• Mulch lightly after soil dries to conserve moisture.
• Monitor: New growth should green up as roots re-establish.

Why This Works

Mulberries are tough desert trees once established. They need deep, infrequent water to develop deep roots—not daily shallow irrigation.
