Systemic Granules
Our analysis of 5 verified rescue cases across 5 plant species shows exactly what causes systemic granules and the most effective fixes.
Quick Summary
The primary issue is not the yellowing spikes (normal post-bloom senescence in orchids like Phalaenopsis), but an unsuitable potting medium causing poor root aeration and health, compounded by insufficient leaves for photosynthesis, leading to overall plant stress and risk of root rot.
Most Effective Solutions
- 1 Cut yellow spike back to 1 inch above healthy tissue to prevent wet wounds.
- 2 Cut second spike just below blooms and above the top node to redirect energy.
- 3 Remove plant from pot, discard seedling plug if present, soak and clean roots, trim mushy or papery roots with sterile snips.
