Expert tips
The key tip
Iberis sempervirens fears winter moisture more than cold. Plant it on a slight mound, with gravel underneath and around it.
The common mistake
Rich or overly thick organic mulch causes winter collar rot.
The pro's trick
Trim lightly after flowering (May-June) to maintain a compact shape and boost density.
Care
Watering
Water moderately during the first year to establish the roots well. Once established, candytuft is very drought-tolerant and needs little water. During periods of regular rainfall, watering is generally not necessary. Avoid excess moisture which can promote root rot.
Exposure
Place this plant in full sun for abundant flowering and dense foliage. It tolerates partial shade but flowering will be less generous. Good exposure also promotes better disease resistance.
Pruning and maintenance
Prune lightly after flowering (June) to maintain a compact habit and encourage branching. An annual pruning of 5 to 10 cm is enough to rejuvenate the plant. Remove dead or damaged stems as soon as they appear.
Soil
Candytuft prefers light, well-drained and even chalky soil. It tolerates poor and rocky soils. A moderate addition of organic matter at planting time is sufficient; overly rich soils promote excessive growth at the expense of flowering.
Fertilizer
An annual application of balanced fertilizer in spring is more than sufficient. Poor soils can benefit from a light fertilizer at the beginning of the growing season. Avoid excess which reduces flowering.
Diseases and pests
Candytuft is generally not very susceptible to diseases. In case of excessive moisture, watch for root rot. Aphids can occasionally colonize young shoots; a water spray is often enough to eliminate them.
Did you know?
Evergreen candytuft is a classic plant in alpine gardens and rock gardens for centuries, particularly appreciated by the Victorians. Its name "sempervirens" literally means "living forever" in Latin, referring to its evergreen foliage that remains green and attractive even in winter. It's an excellent choice for Mediterranean dry gardens and hard-to-reach areas.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
