Expert tips
The key tip
Tulbaghia thrives in poor, dry soil: don't enrich it with fertilizer, as this weakens it and makes it more vulnerable to cold. A layer of gravel on the surface is sufficient.
The common mistake
Regular watering in winter can weaken the bulb through rot.
The pro's trick
Divide the clumps every 3-4 years in spring: you get free plants and revitalize flowering.
Seasonal watch
In early wet autumn, drastically reduce watering from September onwards to prepare the plant for winter dormancy.
Care
Light
Violet tulbaghia requires a location in full sun for generous flowering. At least 6 hours of direct sunlight daily promotes flower production. In very hot climates, some afternoon shade can be beneficial.
Watering
This is a plant with low water needs, accustomed to semi-arid regions. Water moderately during the growing period (spring-summer), then reduce watering in autumn-winter. Allow the soil to dry out slightly between waterings to prevent rot.
Soil
Prefer well-draining, light and slightly sandy soil, such as a mixture of potting soil and coarse sand. A neutral to slightly acidic pH is ideal. Avoid heavy soils that remain permanently damp.
Fertilizing
Apply balanced fertilizer or potassium-rich fertilizer in spring and summer, every 4 to 6 weeks. Reduce applications in autumn. Excess nitrogen promotes foliage at the expense of flowers.
Pruning
Remove spent flowers to encourage continuous blooming. In late winter, clean up dried or damaged stems. Light pruning helps maintain a compact, bushy shape.
Diseases and pests
Tulbaghia is generally robust. Watch for excessive moisture which can cause root or bulb rot. Indoors, mealybugs may occasionally appear; treat with soapy water spray.
Did you know?
Violet tulbaghia is appreciated by butterflies and bumblebees that adore its fragrant, nectar-rich umbels. Its name 'violacea' evokes the mauve hue of its flowers, and the genus 'Tulbaghia' pays tribute to Ryk Tulbagh, a former Governor of the Cape of Good Hope in the 18th century.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
