Cichorium endivia
vegetableBroad-leafed escarole — a less bitter, more substantial relative of curly endive with wide, wavy leaves and a mild bitter edge that mellows beautifully in cooking. A cornerstone of Italian cuisine, particularly in soups like wedding soup and Italian bean soups. Also excellent raw in salads when dressed assertively with anchovy-garlic vinaigrette.

When to Fertilize
At planting; light nitrogen side-dress when heads begin to form
Fertilizer
Balanced granular fertilizer; compost-amended soil preferred
Direct sow or transplant as a cool-season crop. Escarole tolerates more heat than most chicory-family greens but is best in spring or fall. Grows to 12 to 16 inches across in 85 to 95 days. Can be blanched by tying outer leaves over the head for 2 weeks to reduce bitterness. A light frost actually sweetens the leaves considerably. Very cold-hardy — survives light frost with protection.

Good neighbors that attract beneficial insects or deter pests
Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Check inner head leaves; water blast; insecticidal soap; plant alliums nearby
Beer traps; diatomaceous earth; handpick at night after rain
Avoid overhead watering; ensure airflow between plants; copper spray if needed
Well-draining soil; space for airflow at plant base; avoid wetting the crown
Harvest whole heads when fully formed and 12 to 14 inches across. Outer leaves will be dark green and slightly bitter; inner leaves are pale and milder. For cooking, the bitterness dissipates with heat and olive oil. Refrigerate and use within 1 week. Wilted or slightly yellowed outer leaves are still excellent for soups.
Excellent source of vitamins A and K, folate, and fiber. Bitter compounds have historically been used as digestive bitters. Higher in calcium and iron than most lettuce types. Very low in calories. Inulin content supports beneficial gut bacteria.
