Pineapple Guava Yellowing in California Drought: Water and Mulch Strategies

Primary Issue: Water Stress

Yellow leaves with red dots on an older, fruiting pineapple guava in Northern California drought strongly indicate insufficient water, especially with reduced irrigation.

Immediate Actions

• Deep soak the root zone monthly (or per water restrictions).
• Apply 3–4" mulch (wood chips, straw) from trunk to drip line—keeps soil cooler, reduces evaporation.
• Check for soil-wetting agents (e.g., yucca extract products) to improve water penetration in hydrophobic soil.

Organic Aid

Atomic Grow can increase leaf brix, helping cells retain moisture. Apply as foliar spray and soil drench per label.

Product Note

"Saturade" (Japanese water-holding polymer) is no longer imported. Modern equivalents exist—search "soil surfactant" or "wetting agent."
