Ming Aralia Rescue: The Danger of Fungicides and Sterile Soil

A Ming Aralia (Polyscias fruticosa) collapsed after "extra watering" and subsequent fungicide use, then multiple repottings into sterile mixes. The fungicide and sterile soil destroyed beneficial mycorrhizal fungi essential for nutrient uptake.

Why It Worsened

Mycorrhizae deliver nutrients and protect roots. Sterile soil and fungicides eliminate them, making recovery harder. Peat-heavy "seed starter" mix stays too wet for Ming's sensitive roots. Each repotting destroys more root hairs.

Recovery Protocol

1. Stop repotting—only when rootbound (watering every other day)
2. Use living soil: compost, sand, clay, organic matter with natural microbes
3. Or add commercial mycorrhizal inoculant
4. Terracotta pot, one size up only
5. Bright indirect light, minimal water, patience
6. Consider "Messenger" (harpin protein) to stimulate defenses

Ming Aralia Reality

These are notoriously fickle. Mastering one puts you on a short list of successful growers. Each crisis is a lesson.
