When to plant Endive in Temperate Australia
Temperate zone — applies to Sydney, Melbourne, Adelaide, Perth, Newcastle and similar areas. Growing elsewhere? Cool · Subtropical · Tropical · Arid.
Sow endive direct from February to April for an autumn crop and again from August to November for spring, setting seed about 5 mm deep. This hardy salad green germinates in 10–20 days and reaches full size in 50–80 days, so it fills the cooler shoulder seasons neatly. Thin plants to 20–30 cm apart with rows 20–30 cm apart, in moisture-retentive soil and a spot with some afternoon shade in the warmer months. Grown in the milder weather of temperate Melbourne, Adelaide and Sydney, endive stays crisp and only pleasantly bitter rather than harsh.

Growing notes
Endive is grown for its slightly bitter salad leaves, and managing that bitterness is the main craft. Plants grown fast in cool, moist conditions with steady water stay mild and crunchy; those stressed by heat or dry soil turn harshly bitter and bolt to seed. This is why autumn and early-spring sowings suit the temperate zone far better than summer, and why afternoon shade helps during warmer spells around Sydney and Adelaide.
The traditional trick to sweeten the heart is blanching: about two weeks before harvest, gather the outer leaves and tie them over the centre, or cover the plant with an upturned pot to exclude light. The shaded inner leaves lose much of their bitterness and turn pale and tender. Make sure the leaves are dry when you tie them, as trapped moisture in a wet temperate autumn invites rot in the crowded heart.
Keep the water up and even to avoid triggering bolting, and mulch to hold soil moisture. Slugs and snails are the main pest, sheltering in the dense rosettes; check regularly and clear hiding spots nearby.
Harvest whole heads once they reach full size, or pick outer leaves as a cut-and-come-again crop. Do not leave mature plants sitting in warming spring soil, as they will run to seed quickly.

Common questions
- how do you make endive less bitter
- Grow it fast in cool, moist conditions, and blanch the heart before harvest by tying the outer leaves over the centre or covering the plant to exclude light for about two weeks. The shaded inner leaves turn pale and much milder.
- when do you sow endive in a temperate garden
- Sow endive from February to April for an autumn crop and from August to November for spring. Cool shoulder-season weather keeps the leaves crisp and mild, while summer heat causes bitterness and bolting.
- why did my endive bolt to seed
- Bolting is triggered by heat and water stress. Endive sown into warm weather or left short of water runs to flower quickly. Keep to cooler sowing windows, water steadily, and harvest promptly once heads mature.
- what is the difference between endive and lettuce
- Endive is a distinct salad green with a characteristic mild bitterness and a more robust, sometimes frilly leaf, whereas lettuce is milder and softer. Endive is also hardier and better suited to cool-season growing, and it responds well to blanching to reduce its bitterness.
