How to Grow Hebe: Complete UK Care Guide

To grow hebe successfully in the UK, choose a cultivar suited to your climate, as small-leaved, whipcord types are hardiest while large-leaved forms suit milder or coastal gardens. Plant in full sun in free-draining soil, water while establishing, and trim lightly after flowering to keep growth dense and compact.

Difficulty	Easy, particularly hardy small-leaved cultivars

Choosing hebe varieties for UK gardens

Match the cultivar to your garden's exposure: small-leaved, whipcord types survive harder frosts, while large-leaved, big-flowered forms need milder conditions or a sheltered spot. Browse more shrub options in our grow guides hub.

Cultivar	Leaf type	Hardiness	Notes
Hebe cupressoides 'Boughton Dome'	Whipcord (tiny, scale-like)	Very hardy	Neat dome shape, rarely needs pruning
Hebe pinguifolia 'Pagei'	Small, grey-green	Very hardy	Excellent low groundcover, white flowers
Hebe 'Red Edge'	Small-medium, red-margined	Hardy	Good compact form, lilac flowers
Hebe salicifolia	Medium, willow-like	Hardy	Good for hedging, white flower spikes
Hebe 'Great Orme'	Large, glossy	Moderately tender	Long pink flower spikes, needs shelter
Hebe 'Midsummer Beauty'	Large, glossy	Moderately tender	Long lilac-purple flowering season

Where and when to plant hebe

Plant container-grown hebes in spring or early autumn, allowing roots to establish before the extremes of summer heat or winter cold. Choose an open, sunny position with sharp drainage; hebes are excellent for coastal gardens and exposed sites, tolerating salt-laden wind well, but avoid low-lying frost pockets, particularly for larger-leaved cultivars.

How to plant hebe

1. Dig a hole twice the width of the root ball and to the same depth.
2. Improve heavy soil with horticultural grit or well-rotted compost to boost drainage.
3. Remove the plant from its pot and gently tease out any circling roots.
4. Position at the same depth it was growing in its pot.
5. Backfill, firm in gently and water thoroughly.
6. Apply a thin mulch, keeping it clear of the main stems.
7. Water regularly for the first growing season while roots establish.

Watering and feeding

Water newly planted hebes regularly through their first summer, then rely mainly on rainfall once established, as most cultivars are drought-tolerant once rooted in. Avoid waterlogged soil in winter, which is a common cause of losses. Feed lightly in spring with a general-purpose, slow-release fertiliser; hebes generally need little supplementary feeding on reasonable soils.

Pruning hebe

Trim hebes lightly with shears or secateurs immediately after flowering, or in spring for late-flowering cultivars, removing spent flower spikes and a couple of centimetres of growth to encourage a dense, bushy habit. Begin light trimming when plants are young, as hebes do not reshoot reliably from old, bare, woody stems, so hard renovation pruning is often unsuccessful. If frost has damaged growth, wait until new shoots appear in late spring before cutting back to healthy wood.

Propagation

Hebes root readily from semi-ripe cuttings taken in July or August. Select non-flowering side shoots around 10cm long, remove the lower leaves, and insert into free-draining cuttings compost in a cold frame or sheltered spot outdoors. Cuttings usually root within six to eight weeks and can be potted on the following spring, giving an easy and reliable way to increase stock or replace ageing plants.

Growing hebe in pots

Compact cultivars such as Hebe 'Red Edge' and Hebe pinguifolia 'Pagei' are well suited to containers on patios and in courtyard gardens. Use a peat-free, free-draining compost with added grit, and choose a pot with generous drainage holes. Water regularly through the growing season, but reduce watering in winter to avoid waterlogging, and move pots to a sheltered spot during severe cold snaps.

Common problems

Problem	Symptom	Fix
Downy mildew	Pale patches on upper leaf surface, greyish growth beneath	Improve air circulation, remove affected leaves, avoid overhead watering
Leaf spot	Dark, circular spots on leaves	Remove and destroy affected foliage, avoid overcrowding
Frost damage	Blackened leaves and stem dieback after cold snaps	Choose hardier small-leaved cultivars in cold gardens; delay pruning until new growth shows
Waterlogging	Yellowing leaves, root rot, sudden collapse	Improve drainage, avoid heavy wet soils, raise containers off the ground
Leggy, bare growth	Sparse foliage low down, flowering only at shoot tips	Trim lightly and regularly from a young age; replace very old, woody plants

Month-by-month care calendar

Month	Task
January	Check for frost or wind damage; avoid pruning while frosts continue
February	Plan new planting; order cultivars for spring
March	Apply light feed; plant new container-grown hebes
April	Prune frost-damaged growth once new shoots appear
May	Water newly planted specimens regularly
June	Watch for downy mildew in humid weather
July	Take semi-ripe cuttings; trim early-flowering types once blooms fade
August	Continue trimming after flowering; pot on rooted cuttings
September	Plant new hebes while soil is still warm
October	Enjoy late flowers on autumn-blooming cultivars
November	Move tender potted hebes to a sheltered spot
December	Check drainage around containers ahead of winter rain

With the right cultivar for your conditions, hebes provide reliable, low-maintenance structure and colour for much of the year. Explore more resilient shrubs in our plants hub or see seasonal planting ideas in our seasonal guide.
