Dianthus Growing Guide

Dianthus, also known as Pinks

Crop Rotation Group

Miscellaneous 

Soil

Average garden soil with excellent drainage.

Position

Full sun.

Frost tolerant

Annual dianthus tolerates light frost with ease, but can be damaged by hard freezes.

Feeding

Encourage fast growth by mixing a balanced organic fertiliser into the soil before planting.

Companions

Thyme. Dianthus combines well with other cold-tolerant annuals including pansies, cineraria, and ornamental cabbage and kale.

Spacing

Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)

Sow and Plant

Set out stocky seedlings in early spring, or in autumn where winters are mild.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

Dianthus blooms earlier than other annuals, and well-sited plants may persist for two years in areas with mild winters. Colours include pink, red, lavender, white and many bicolours.

Harvesting

Some varieties have stems long enough for cutting. As flowers fade, snip them off with scissors to keep the plants looking neat.

Troubleshooting

Both rabbits and deer like to nibble dianthus foliage. In summer, spider mites cause occasional problems and can be controlled with insecticidal soap.
