When to Plant
Plant bulbs in autumn to allow for root establishment before winter, ensuring vibrant blooms in late spring to early summer.
How to Plant
- Soil Preparation: Use well-draining soil enriched with compost or organic matter. For pots, choose a quality potting mix with good drainage. Top dress with a complete fertiliser.
- Light Conditions: Position in full sun to part shade, ensuring some afternoon shade in hotter climates.
- Planting Depth and Spacing: Plant bulbs 8 cm deep and 15 cm apart, covering with soil and watering thoroughly.
- Mulching: Apply a light mulch layer to retain moisture and regulate soil temperature.
Aftercare
- Watering: Water deeply after planting and maintain moisture during the growing season. Reduce watering as the plant enters dormancy.
- Fertilising: Use a complete fertiliser when foliage emerges to support strong growth and flowering.
- Pruning: Deadhead spent flowers to direct energy to bulb development. Allow foliage to naturally die back before trimming.
Division
Leave clumps undisturbed for several years but divide during dormancy (late autumn to early winter) if overcrowding reduces flowering. Lift the clumps, separate bulbs by hand, and discard damaged ones. Replant immediately or store in a cool, dry place. Water after replanting to help the establishment.
Pests and Diseases
‘Arab’s Eye’ is generally low maintenance but may encounter:
- Bulb Rot: Avoid overwatering and ensure well-draining soil to prevent rot.
- Fungal Issues: Powdery mildew or botrytis can occur in humid conditions; space plants well and avoid overhead watering.
- Slugs and Snails: Use traps or barriers to protect plants in damp areas.
- Aphids: Control infestations with neem oil or insecticidal soap.
