How to grow Fragrant Balm

Written by the GardenDecoded editorial team · Last reviewed 21 July 2026 · Written for UK gardens · How we research our guidance

Planting

Plant in spring in soil improved with compost. Dry roots are the usual cause of failure and of bad mildew, so pick a spot that stays moist and mulch in spring. Give it air movement as well — a crowded, still corner makes mildew worse.

Pruning

Deadhead to extend flowering. Cut stems back in late autumn or leave the seed heads standing for winter and cut down in early spring.

Propagation

Divide in spring every two or three years, keeping the vigorous outer growth. Basal cuttings in spring root easily.

Pests and diseases

Powdery mildew is the recurring problem, and a dry summer will bring it on almost every time. Keeping the roots moist and dividing regularly helps more than anything sprayed on the leaves.

Value to wildlife

Very good for bees, and the shaggy tubular flowers are worked by long-tongued bumblebees in particular. Leaving seed heads gives winter food for small birds.

Notes

It spreads by shallow runners and the centre of the clump goes bare after a few years. Regular division keeps it both vigorous and in bounds.
