Expert tips
The key tip
Plant bulbs from September to October in well-draining soil, pointy end up, 5-8 cm deep. No amendments needed if the soil is correct.
The common mistake
Planting too late (December) or in wet soil: bulbs rot before they can root.
The pro's trick
Pinch off faded flowers with your fingernails as soon as they drop: this saves the bulb's energy, so it'll thicken up for next year instead of making seeds.
Care
Exposure
Golden crocus demands full sun exposure for generous and colorful flowering. It tolerates light partial shade in very hot regions. Plant it in an open location not shaded by leafy trees.
Watering
Water needs are very low once the bulb is established. Water moderately at planting to promote rooting. In autumn and winter, natural rainfall is generally sufficient. Avoid excess moisture, which could cause bulb rot.
Soil
Crocus chrysanthus prefers well-drained, light soil. Potting soil enriched with sand or coarse gravel works perfectly. Avoid compact and permanently damp soils. Adding compost at planting time helps establishment.
Fertilizer
A moderate application of balanced fertilizer in spring, after flowering, promotes nutrient storage in the bulb for following years. Choose formulas low in nitrogen to avoid excessive foliage at the expense of flowers.
Pruning and maintenance
Let the foliage dry naturally after flowering: it replenishes the bulb's reserves. Remove only faded flowers to prevent unnecessary seed formation. No strict pruning required.
Diseases and pests
Crocus chrysanthus is generally very hardy and rarely subject to diseases. Monitor for bulb rot if drainage is insufficient. Voles can occasionally damage bulbs; light mulching can help deter them.
Did you know?
Golden crocus is one of the first flowers to bloom in spring in mountainous areas, sometimes as early as February. Its name 'chrysanthus' literally means 'with golden flowers' in ancient Greek. Long ago, peoples of Mediterranean regions used it in rituals celebrating seasonal renewal.
Where to buy it
Plant the bulbs in autumn for spring flowering. Pick a plant with healthy foliage and roots that are not exposed. Best time: from September to November.
