How to grow Bearded Pink

Sunlight
Full sun
Watering
Moderate
Soil
Well-drained, moderately fertile
Soil pH
Neutral to alkaline

Planting

This is a biennial in practice: sow in late spring or early summer, grow the plants on through summer, and plant them into their flowering positions in autumn for flowers the following year. It does well on chalk and dislikes heavy wet ground over winter. Space about 25 cm apart.

Pruning

Deadhead as flowers fade to extend the display. Most plants are pulled out after flowering, though some will survive a further year if cut back hard; the second-year display is usually weaker.

Propagation

Seed sown in a nursery bed or trays in May or June is the standard method and is straightforward. Plants also self-seed where the soil is open.

Pests and diseases

Rust and leaf spot in damp conditions. Slugs damage young plants, and stem rot occurs in soil that stays wet in winter.

Value to wildlife

The scented flowerheads attract bees, butterflies and day-flying moths through early summer.

Notes

The main mistake is treating it as a permanent perennial. Sow a fresh batch every year, and you will have a reliable succession rather than a gap every other summer.
