Expert tips
The key tip
Nerine bowdenii loves shallow bulbs, in sunlight, with dry rest after flowering.
The common mistake
Watering or moving bulbs in summer disrupts the following autumn's bloom.
The pro's trick
Plant with the upper third of the bulb exposed above soil—it's not a mistake, it's normal for this species and prevents rot.
Seasonal watch
In September-October, watch for the first flower buds emerging before the leaves: that's a good sign.
Care
Exposure and climate
Nerine bowdenii loves full sun, which is essential for generous flowering. Place it in a warm, open location. It tolerates moderate winter frosts but prefers a spot sheltered from strong autumn winds.
Watering
Water requirements are low. Water regularly during spring and summer growth, then gradually space out waterings as autumn approaches. In winter, with foliage gone, reduce watering to the bare minimum or stop altogether.
Soil and planting
Choose well-draining, light, and slightly fertile soil. A sandy or gravelly mix works perfectly. Plant the bulbs in summer (June-July), with the neck slightly emerging, as they fear rot in overly moist soil.
Fertilizing
Apply a balanced or potassium-rich fertilizer in spring when growth restarts. Repeat the application once or twice before autumn flowering. Too much nitrogen promotes foliage at the expense of flowers.
Cleaning and pruning
No pruning is necessary. Simply remove faded flowers to extend flowering and encourage seed formation if desired. Remove dead foliage in winter when it naturally dries.
Pests and diseases
Nerine is generally robust. Be careful to avoid excess moisture, which can promote bulb rot. Inspect regularly for mealybugs or spider mites, especially if the plant is grown in a pot indoors.
Did you know?
Discovered at Kew Botanical Garden in England in the 19th century, Nerine bowdenii owes its scientific name to John Bowden, a passionate British botanist. This South African bulb adapted remarkably well to English and Mediterranean gardens, where it flowers just as most other plants enter dormancy, offering an exotic touch to European autumns.
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.
