Expert tips
The key tip
Dianthus deltoides prefers very well-draining soil and regular but sparse watering. Pinch young stems in May to encourage branching and abundant flowering.
The common mistake
Watering like you would a vegetable garden promotes heart rot and fungal diseases.
The pro's trick
In May, before the flowering rush, pinch off the tips of stems: you'll get twice as many flowers on each branch.
Care
Exposure
Maiden pink requires a location in full sun to flourish fully and produce abundant flowering. It tolerates slightly shaded areas but will flower less generously. Avoid overly shaded spots that promote etiolation.
Watering
Keep the soil regularly moist but well-drained, especially during growth and flowering. Reduce watering in winter and after flowering. Avoid waterlogging which causes root rot. Watering in late afternoon limits fungal diseases.
Soil
Favor light, well-drained soil that is slightly alkaline or neutral. Adding sand or gravel improves drainage, which is particularly important for this species that fears stagnant moisture. Poor to average soil works perfectly.
Pruning and cleaning
Regularly remove spent flowers to extend flowering and stimulate the appearance of new buds. In late summer or early autumn, cut back the foliage slightly to maintain a compact shape. Cleaning dead parts in late winter helps spring vigor.
Fertilizer
A moderate application of balanced fertilizer in spring is generally sufficient. In poor soil, a light feeding every two months during flowering supports flower production. Avoid excess nitrogen which favors foliage at the expense of flowers.
Diseases and pests
Maiden pink is generally robust but can be affected by powdery mildew in humid and stagnant atmospheres. Aphids and spider mites may occur in hot, dry weather. Good air circulation and regular watering limit these problems.
Did you know?
Maiden pink bears the Latin name 'deltoides' because of the shape of its leaves which resemble the Greek letter delta (Δ). This small robust perennial is highly valued in rock gardens and alpine borders, where it naturally colonizes rocky, well-drained spots, recreating the atmosphere of its mountainous habitats of origin.
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.
