How to grow cut leaf daisy
Overview
Cut leaf daisy (Brachyscome multifida) is a compact, herbaceous perennial native to eastern Australia, grown for its finely divided foliage and prolific daisy-like flowers. It is a reliable filler plant for borders, rockeries, and containers, providing long-lasting colour from spring through autumn.
Varieties
- Brachyscome multifida 'White Delight' — A compact white-flowered form that blooms profusely from spring to autumn, popular in Australian gardens.
- Brachyscome multifida 'Mauve Delight' — Produces soft mauve flowers with a longer flowering period, ideal for mass planting in borders.
Soil Preparation
Prefers a slightly acidic to neutral pH (6.0–7.0) in well-drained sandy loam or loamy soil. If growing in heavy clay, amend with coarse sand and compost to improve drainage. A light application of organic matter at planting helps establish roots.
Growing Guide
Plant in well-drained soil in a position that receives morning sun and afternoon shade, especially in warmer zones. Space plants 25–30 cm apart to allow for spreading growth. Water regularly to keep the soil evenly moist but not waterlogged, and apply a light mulch to retain moisture and suppress weeds. Deadhead spent flowers every few weeks to extend the flowering season.
Sowing
Sow seeds on the surface of a fine seed-raising mix and barely cover; they need light to germinate. Keep moist at 18–22°C; germination takes 10–14 days. Transplant seedlings when they reach 5–8 cm tall, spacing 25–30 cm apart. Direct sowing is possible in mild climates after frost risk passes.
Care
Feed in early spring with a balanced slow-release fertiliser (e.g., 8–4–6) and again after the first major flowering flush. Lightly prune back by one-third after each flowering cycle to maintain a compact shape and encourage repeat blooming. Remove spent flower heads regularly to keep the display tidy.
Companion Planting
Pair with other low-growing natives such as Scaevola (fan flower), Goodenia, and Chrysocephalum (strawflower) for a cohesive Australian garden. Avoid planting near aggressive spreaders like Mentha (mint) or vigorous grasses that may outcompete it.
Common Pests & Risks
Aphids may cluster on new growth in spring; spray with a strong jet of water or use a dilute neem oil solution. Fungal diseases like powdery mildew can appear in humid conditions—improve air circulation by spacing plants and avoid overhead watering. Snails and slugs may damage young foliage; control with iron-based pellets or beer traps.
Troubleshooting
Yellowing leaves: often caused by overwatering or poor drainage—reduce watering and check soil drainage. Brown leaf edges: usually from dry soil or hot afternoon sun—increase watering or provide more shade. Leggy growth: insufficient light or lack of pruning—move to brighter spot and trim back. Powdery mildew: fungal issue in humid conditions—improve air circulation and apply a sulfur spray. Aphid clusters: common in spring—spray with neem oil or insecticidal soap.
