Diagnosing a Declining Mature Aloe: Trunk Rot vs. Seasonal Stress

Key Diagnostic: Check the Trunk

For a 4-year-old aloe showing color loss, reddening, and oozing leaves, the critical test is trunk firmness. Gently squeeze the main stem near the soil line:

• Soft/mushy trunk: Crown rot has advanced; plant cannot be saved.
• Firm trunk: There's a chance to propagate from a healthy top cutting.

Understanding Aloe's Seasonal Quirks

Aloes are southern hemisphere natives—their growth cycle is opposite to northern seasons. They actively grow in winter and rest in summer. Watering during summer dormancy, combined with heat stress, commonly causes the symptoms described: translucent/red leaves, mushiness, and sap leakage.

If Trunk Is Firm: Emergency Propagation

1. Cut 4–6 inches above any damaged tissue.
2. Callus the cutting for 2–3 weeks in shade.
3. Plant in dry cactus mix; wait 2 weeks before first watering.
4. Provide bright, indirect light (15 hrs/day ideal).

Note: Aloes are notoriously difficult to root from stem cuttings. Success rates are low; consider starting fresh with a pup if available.
