Frequently Asked Questions

What pest or disease problem commonly affects Lactuca sativa (Lollo Rossa/Bijou), and how do I manage it?

Lettuce (Lactuca sativa) is especially prone to downy mildew and aphids, and dense, cool-wet conditions can trigger rapid mildew spread. Improve airflow by spacing plants and watering at the base, then remove heavily affected leaves; for aphids, spray plants with a strong stream of water and repeat every 2–3 days for a week to dislodge them.

How often should I water Lactuca sativa during the main growing phase for best head/leaf quality?

During active growth (roughly weeks 2–6), keep the soil consistently evenly moist but not soggy, aiming for the top 1 inch to stay damp. Water deeply about 1–2 times per week depending on heat, and increase to more frequent light watering only if the soil dries out quickly—lettuce that dries and re-wets repeatedly tends to get bitter and go to seed early.

How can I tell when Bijou (Lactuca sativa) is ready to harvest?

Harvest about 50 days from sowing when leaves are fully formed and tender, with each plant reaching its typical rosette size for Lollo Rossa. Pick in the morning and look for crisp texture—if leaves start to look elongated or the plant begins stretching upward, harvest immediately before it turns bitter or bolts.

Tender, jewel-toned leaves unfurl with a crisp, water-bright snap—Bijou loose-leaf lettuce brings a fresh, sweet-green flavor that feels clean and lively from the first handful. The foliage forms an airy rosette of finely textured, delicately ruffled leaves, delivering a pleasantly buttery bite without heaviness. Grow Bijou for salads and quick tosses, or for vibrant garnishes that add color and crunch to greens-forward plates.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 32°F before moving outdoors. Harden off for 5 days first.

Expert Note

Grow Bijou like a cool-season crop—keep it from overheating to avoid bitterness and bolting.
