When to plant Endive in Tropical Australia
Tropical zone — applies to Darwin, Cairns, Townsville, Broome, Mackay and similar areas. Growing elsewhere? Temperate · Cool · Subtropical · Arid.
Sow endive direct from March to July, with an extra window in November, setting seed about 5 mm deep as the dry season runs through Darwin, Cairns and Townsville. It germinates in 10–20 days and hearts up in 50–80 days. Thin or space plants 20–30 cm apart in rows 20–30 cm apart so each rosette has room to fill out. Endive is a cool-preferring salad green, so the drier, milder months give you crisp, mild leaves, while wet-season heat makes it bolt and turn bitter. Keep the bed evenly moist and consider blanching the hearts for sweeter, paler centres.

Growing notes
Endive belongs to the chicory family and, like most salad greens, does best in the tropics through the cooler dry season, so aim your main sowings from March to July with a late window in November around Cairns and Townsville. Sow into rich, moisture-retentive soil and keep it steadily watered, because any check in growth pushes the leaves toward bitterness.
The leading failure mode here is bolting and bitterness. Sown too close to the hot, humid months, endive runs to seed quickly and the leaves turn harshly bitter. The fixes are timing, even moisture, and picking before plants are stressed by heat. Blanching, tying up the outer leaves or covering the heart for a week or two before harvest, excludes light and produces sweeter, paler, more tender centres, which is the traditional way to tame endive's natural bite.
Wet-season humidity brings rots and slugs to the dense rosettes, so space plants well for airflow, keep mulch clear of the crowns, and avoid overhead watering late in the day. Aphids can also gather in the crowded hearts, so check regularly. Harvest whole heads at 50–80 days, or pick outer leaves cut-and-come-again style, and keep the crop moving before the humidity climbs.

Common questions
- When can I grow endive in the tropics?
- Sow direct from March to July, with an extra window in November, through the cooler dry season. Endive prefers mild conditions, so the dry months give crisp, mild leaves, while wet-season heat makes it bolt and turn bitter.
- Why is my endive so bitter?
- Heat, stress and age all sharpen endive's natural bitterness. Grow it through the dry season, keep moisture even, and harvest before plants are heat-stressed. Blanching the hearts for a week or two before picking gives noticeably sweeter, paler centres.
- How do I blanch endive?
- About a week or two before harvest, gather the outer leaves and tie them over the heart, or cover the plant to exclude light. The shaded inner leaves lose their bitterness and turn pale and tender, which is the classic way to prepare endive.
- How far apart should endive be planted?
- Space plants 20–30 cm apart in rows 20–30 cm apart. That spacing lets the rosettes heart up fully and keeps airflow between plants, which reduces rot in the humid tail of the growing season around Townsville and Cairns.
