Red Apple Groundcover Yellowing in San Diego: Iron Deficiency and Watering

Background

Red apple (Aptenia cordifolia) often turns chlorotic (yellow) from iron deficiency, even when established. It’s a rampant grower needing frequent trimming.

Adjustments for San Diego

• Water very little: once a week, 4 minutes max.
• Use slow-release fertilizer with iron.
• Consider replacing with Myoporum ‘Pink’ (drought-tolerant, low-maintenance).

Overwatering and poor nutrition cause yellowing.
