Camellia Deaths in Central Valley: Drainage and Soil Organic Matter

Root Cause

Camellias dying despite irrigation in Shafter, CA (hot summers, 30s winter) likely have poor drainage or compacted soil causing root rot. Low desert conditions exacerbate.

Remediation

Check drainage—water must percolate. Amend with compost + humic acid or quality organic soil amendment. Improve soil structure to prevent waterlogging.
