Endive
Cichorium endivia
Endive is a cool-season rosette green suited to direct sowing or transplanting in spring and autumn slots. Mild flavor often improves in cool weather, and blanching the center can reduce bitterness in heading types. Maturity runs roughly 50–90 days from sowing with part-sun tolerance down to about four hours of direct light.

Sow or transplant in cool weather.
Either direct sow outdoors from four weeks before the last frost through the frost date, or start indoors 4–6 weeks before frost at about 0.6 cm depth. Germination typically needs 5–10 days in cool, moist seedbeds.
Light frost tolerance supports early outdoor sowings and late-season stands. Resow about every 21 days when temperatures stay mild enough for rosettes to size up without immediate bolting.

Give rosettes room to spread.
Allow 20–30 cm between plants and 45 cm between rows so rosettes can spread without crowding. Wider spacing helps airflow around dense leaf cups, especially before blanching.
Containers need at least 25 cm depth and about 7 litres of medium. Compact space need still requires room for the full rosette diameter at harvest.

Blanch hearts to tame bitterness.
Four hours of direct sun satisfies the part-sun label, though brighter cool sites thicken leaves faster. Moderate water at 25–35 mm weekly with pH 6.0–7.5 keeps growth steady.
Cool weather produces milder leaves, as noted in the key tip. Tie or cover inner leaves for a week or two to blanch the heart when reduced bitterness is desired.
Sunlight
Part sun tolerant (4+ direct-sun hours/day)
Soil pH
A suitable acidity range for general growth.
Weekly water
Moderate water need.
Aim for even moisture and water deeply when the upper 2-3 cm of soil begins to dry.
Harvest whole heads from sowing.
Expect 50–90 days from sowing for full rosettes, with harvest basis counted from sowing. Cut whole heads at the base once size and leaf texture meet your use, or harvest outer leaves earlier if the variety supports it.
Plants may behave as annual or biennial in the record, but home gardeners usually finish the crop in one cool season. Heat and long days can push endive toward bolting, so shift sowings to cooler windows.

Endive growing questions
How can endive bitterness be reduced?
Cool weather produces milder leaves, and blanching the center by covering inner leaves can further reduce bitterness, matching the key tip for heading types.
Can endive tolerate frost?
Frost tolerance is light frost, which supports early spring sowings and late autumn growth in many climates without immediate loss of the stand.
Should endive be direct sown or transplanted?
Either method fits the record: direct sow in the outdoor frost window or start indoors 4–6 weeks before the last frost, then transplant into the same cool-season slot.
What succession timing is listed for endive?
Resow about every 21 days when temperatures remain cool enough for rosettes to mature within the 50–90 day harvest range from sowing.
