How to grow endive
Overview
Endive (Cichorium endivia) is a leafy vegetable grown for its slightly bitter leaves, ideal for salads and cooking. It thrives in cool-season conditions with full sun and well-drained soil. Blanching the inner leaves by tying the outer foliage together reduces bitterness and produces a tender, pale heart.
Varieties
- Batavia — A curly-leaved variety with a crisp texture and slightly bitter flavour, popular in Australian gardens.
- Rica — A smooth-leafed endive with a mild, sweet taste, ideal for salads.
- Galante — A broad-leaved type with excellent cold tolerance and good bolt resistance.
- Midi — A compact variety suitable for pots and small spaces, producing tender hearts quickly.
Soil Preparation
Endive prefers well-drained, fertile soil with a pH of 6.0–7.0. Enrich beds with well-rotted compost or aged manure before planting, and work in a handful of blood and bone per square metre. Good drainage is critical to prevent root rot and fungal issues.
Growing Guide
Sow seeds 5mm deep, 30cm apart in rows 45cm apart, thinning to 30cm spacing. Keep soil consistently moist, especially during head formation. For best quality, grow in cool weather; warm conditions cause bitterness and bolting. Two to three weeks before harvest, blanch heads by gathering and tying outer leaves with string or a rubber band. Succession sow every 2–3 weeks for a continuous supply.
Sowing
Sow seeds directly 5mm deep, 30cm apart in rows 45cm apart. Germination takes 7–14 days at soil temperatures of 10–20°C. Seedlings can be started in punnets and transplanted at 4–6 weeks old, but direct sowing produces stronger plants.
Care
Apply a balanced liquid fertiliser every 2–3 weeks during active growth to maintain vigour. Remove yellowing outer leaves to prevent disease and improve airflow. Keep soil evenly moist but not waterlogged; mulch around plants to conserve moisture and suppress weeds.
Companion Planting
Endive grows well with radishes, carrots, lettuce, onions, and beetroot. Avoid planting near pole beans or strawberries, which can stunt growth or attract pests. Good companions share similar soil and moisture needs without overcrowding.
Common Pests & Risks
Slugs and snails are the primary pests; use beer traps, copper tape, or diatomaceous earth around plants. Aphids may also appear; treat with insecticidal soap or neem oil. Keep the garden free of debris to reduce hiding spots and improve air circulation.
Harvesting
Harvest whole heads by cutting at the base when the centre is dense and pale, typically 80–100 days from sowing. For a cut-and-come-again approach, pick individual outer leaves once they are large enough. Blanched heads offer milder flavour and should be harvested promptly to avoid deterioration.
In the Kitchen
Endive leaves add a pleasant bitterness to salads; they also work well braised, grilled, or sautéed to mellow the flavour. Store harvested heads in the fridge for up to a week. Pair with citrus, honey, or creamy dressings to balance the bitterness.
Troubleshooting
Yellowing outer leaves: normal aging or nitrogen deficiency – apply a liquid feed. Brown leaf edges: inconsistent watering or tipburn – maintain even soil moisture. Bolting: caused by heat or stress – plant in cool weather and harvest promptly. Slug holes: slugs are active – use traps or barriers. Wilting: root rot from overwatering – improve drainage.
