Frequently Asked Questions

What pest or disease commonly affects Cichorium endivia (green curled ruffec), and how do I treat it?

Watch for aphids and slugs/snails, which are common on endive as it forms rosettes. Rinse aphids off with a strong jet of water and, if needed, spot-treat with insecticidal soap; for slugs/snails, hand-pick at dusk and use an iron-phosphate bait or a physical barrier around plants. If you see fuzzy gray growth or leaf spotting, remove affected leaves promptly and improve airflow by thinning so the foliage dries quickly after watering.

How often should I water green curled ruffec endive during its main growing phase?

Keep the soil evenly moist but not waterlogged from transplanting through the 45–55 day growth window. Aim for watering about 1–2 times per week, increasing to more frequent watering in warm, drying weather, and water at the soil line to avoid wet leaves. The target is consistently damp soil 1–2 inches down—if the top inch dries out, endive leaves can turn bitter and growth slows.

How can I tell when Cichorium endivia ‘green curled ruffec’ is ready to harvest?

Harvest at about 55 days (as days to maturity indicate) when the plant has a full, firm rosette with curled leaves that hold their shape. Cut the whole head at the base with a sharp knife; avoid waiting until the center loosens or plants bolt, which makes leaves more bitter and tougher. For best quality, harvest in cool weather and pick before heavy heat spells when possible.
