How to Grow Foxglove
Digitalis purpurea
Foxgloves thrive in partial shade with moist, well-drained soil. Once established they self-seed freely, creating natural drifts. Cut back spent flower spikes to encourage a second flush or leave some to set seed for next year's plants.
Yearly Lifecycle
Care Essentials
Apply a light balanced fertiliser in spring as new growth emerges. Avoid overfeeding — foxgloves are not heavy feeders.
Watch For
- Slugs and snails (especially on young growth in spring)
- Powdery mildew in dry summers
- Foxglove rust
- Crown rot in waterlogged soil
Companions
Ferns, Hostas, Astilbe, Aquilegia

☀️ Light
Partial shade; tolerates sun with moist soil
Thrives in partial shade but tolerates full sun if the soil stays consistently moist. Ideal under deciduous trees or on a north-facing border.
💧 Watering
Keep moist in growth; avoid winter wet
Keep soil evenly moist throughout the growing season. Foxgloves dislike drought — wilting flower spikes are a sign of water stress. Avoid waterlogging in winter.
🌱 Fertilizing
Light spring feed only
Apply a light balanced fertiliser in spring as new growth emerges. Foxgloves are not heavy feeders — overfeeding produces lush foliage at the expense of flowers.
✂️ Pruning
Deadhead for second flush; cut back in autumn
Cut spent flower spikes back to a strong side shoot to encourage a second flush, or leave some to set seed for self-seeding. Cut all growth back in autumn.
🍂 Mulching
Autumn mulch for winter protection
Mulch around the crown in autumn with compost or bark to protect roots over winter and retain moisture. Keep mulch slightly away from the crown to prevent rot.
Growing Tips
Protect young growth from slugs
Slugs and snails are the main threat to foxgloves in spring. Use copper barriers, beer traps, or biological nematode controls as soon as new growth appears.
Leave some spikes for self-seeding
Foxgloves self-seed freely and this is one of their great charms. Leave a few spent spikes on the plant to ripen and drop seed — you'll get natural drifts of new plants the following year.
Deadhead for a second flush
Cutting spent spikes back to a strong side shoot encourages a second, shorter flush of flowers later in the season. Do this promptly after the main flowering period.
Mulch in autumn for winter protection
Apply a layer of compost or bark around the crown in autumn to protect roots over winter and suppress weeds. Keep mulch slightly away from the crown to prevent rot.
Pests & Diseases
Pest Slugs and Snails
Identification: Ragged holes in leaves; young shoots eaten to the ground; slime trails around the crown
- Apply biological nematode control (Phasmarhabditis hermaphrodita) in early spring before growth emerges
- Use copper tape, beer traps, or grit barriers around the crown
- Apply ferric phosphate slug pellets around emerging growth from late winter
Pest Aphids
Identification: Clusters of green or black aphids on flower buds and stem tips; sticky honeydew; distorted buds
- Blast off with a strong jet of water
- Encourage ladybirds and hoverflies
- Spray with a pyrethrin-based insecticide before flowers open if infestation is severe
Disease Powdery Mildew Erysiphe digitalis
Symptoms: White powdery coating on leaves and stems; affected leaves may yellow and drop
Treatment: Remove badly affected leaves; improve air circulation by thinning crowded growth
Prevention: Ensure good spacing; water at the base rather than overhead; mulch to retain soil moisture
Disease Foxglove Rust Puccinia digitalis
Symptoms: Orange or brown pustules on the undersides of leaves; yellow patches on upper leaf surface; leaves may wither
Treatment: Remove and destroy affected leaves promptly; clear all debris in autumn
Prevention: Ensure good air circulation; avoid overhead watering; do not compost affected material
Disease Crown Rot
Symptoms: Soft, mushy crown at soil level; shoots fail to emerge or collapse shortly after; foul smell
Treatment: Remove and destroy affected plants; do not replant foxgloves in the same spot
Prevention: Ensure excellent drainage; avoid mulching directly against the crown; do not overwater
