How to Grow Gaillardia
Gaillardia grandiflora
Gaillardia is a sun-loving, drought-tolerant perennial that flowers prolifically from early summer until frost. Bold red and yellow daisy-like blooms attract pollinators all season. Plant in full sun with well-drained soil — it hates wet feet in winter. Short-lived (3-4 years) but self-seeds freely. Deadhead regularly to extend flowering, or leave some heads to set seed for next year.
Yearly Lifecycle
Care Essentials
Minimal feeding needed. A light compost mulch in spring is sufficient. Over-feeding produces floppy growth and fewer flowers.
Watch For
- Powdery mildew
- Aphids
- Leaf spot
- Root rot in wet soil
Companions
Echinacea, Rudbeckia, Ornamental grasses, Salvia

☀️ Light
Full sun essential
Requires at least 6 hours of direct sun daily. More sun means more flowers. Will not thrive in shade or part-shade — becomes leggy and flowers poorly.
💧 Watering
Very low — drought tolerant
Water new plantings until established. Once settled, gaillardia is extremely drought-tolerant and prefers dry conditions. Overwatering is far more harmful than underwatering.
🌱 Fertilizing
Do not over-feed
Lean soil produces the best plants. A light compost mulch in spring is the maximum needed. Rich feeding produces tall, floppy growth that needs staking and reduces flower production.
✂️ Pruning
Deadhead regularly; cut back in autumn
Remove spent flowers throughout summer to encourage continuous blooming. Cut all growth to ground level in late autumn after the first hard frost.
🍂 Mulching
Gravel mulch preferred
A thin gravel or grit mulch around the crown helps drainage and prevents rot. Avoid organic mulches that hold moisture against the crown over winter.
Growing Tips
Drainage is everything
Gaillardia thrives in poor, sandy, even gravelly soil. Rich, heavy or wet soil kills it over winter. If your soil is clay, add generous grit at planting time or grow in raised beds.
Deadhead for months of colour
Regular deadheading extends flowering from June right through to October. Cut stems back to a leaf node rather than just removing the flower head.
Short-lived but self-sowing
Individual plants last 3-4 years. Leave a few seed heads in late summer to allow self-sowing — seedlings appear the following spring and flower in their first year.
No staking needed
In lean soil, gaillardia stays compact and upright. Floppy growth is a sign of over-feeding or too much shade — move to a sunnier, poorer spot.
Pests & Diseases
Pest Aphids
Identification: Clusters of small green or black insects on shoot tips and developing buds, often with sticky honeydew
- Blast off with a strong water jet
- Spray with fatty acid insecticide
- Encourage ladybirds and lacewings
- Spray with a contact insecticide containing deltamethrin
Disease Powdery Mildew
Symptoms: White powdery coating on leaves and stems, causing yellowing and reduced vigour
Treatment: Remove badly affected leaves. Improve air circulation around plants
Prevention: Space plants well, avoid overhead watering, ensure good airflow
Disease Root Rot
Symptoms: Plants wilt despite moist soil, crown turns brown and mushy, roots are dark and soft
Treatment: Remove and destroy affected plants. Do not replant in the same spot without improving drainage
Prevention: Plant in well-drained soil, add grit to heavy clay, avoid overwatering
Disease Leaf Spot Septoria spp.
Symptoms: Brown or black spots on leaves, sometimes with yellow halos. Lower leaves affected first
Treatment: Remove and destroy affected leaves. Improve air circulation
Prevention: Avoid overhead watering, space plants adequately, remove debris in autumn
