Yellowing Base on Euphorbia hermentiana After Repotting

Post-Repotting Decline: Likely Rot from Poor Drainage

Two Euphorbia hermentiana moved from root-bound pots to larger pots with cactus soil around base but regular potting soil above. No drainage holes. Watered 1–2x/month. Bases turning yellow, stems limp, two stalks black and shriveled.

Problems

• Regular potting soil holds too much water.
• No drainage holes = waterlogging risk.
• Watering too soon after repot (should wait 1–2 weeks).
• Winter dormancy: Euphorbias need very little water now.

Rescue Attempt

1. Check for rot (soft yellow areas).
2. Take cuttings from healthy offshoots.
3. If no rot, let dry a few days, repot in soilless mix in pots with drainage.
4. Wait a week before watering.
5. Root cuttings similarly after callousing.

Timing

Not ideal season (dormancy), but action needed to save something.
