Troubleshooting
Two-leaf Squill problems — and how to fix them
Two-leaf Squill (Scilla bifolia) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Over-aggressive spreading
In ideal conditions S. bifolia can spread beyond desired boundaries via prolific self-seeding. Deadhead if spread needs controlling, but for naturalising effects allow seed to disperse freely.
Bulb rot in heavy soils
Poor drainage over winter or summer dormancy leads to bulb rot, particularly in clay soils. Incorporate grit when planting and choose a site with good natural drainage, especially on slopes or beneath trees.
Short flowering window
Individual plants bloom for only 2–3 weeks in late winter. Plant in large drifts and combine with other early bulbs (Galanthus, Eranthis) to extend seasonal interest, as there is no way to prolong the bloom period.
Prevent two-leaf squill problems before they start
Most two-leaf squill issues are care-mismatch, not bad luck. Dial in the basics:
