Frequently Asked Questions


How do I manage downy mildew or leaf spot on Lactuca sativa (Sanguine Améliorée) at home?
Lactuca sativa commonly gets downy mildew and foliar leaf spots when leaves stay wet; water early in the day and keep water off the foliage. If you see yellowing patches with fuzzy growth on leaf undersides or dark spots spreading, remove affected leaves immediately and increase airflow by spacing plants and thinning as they develop. Use a protective fungicide labeled for lettuce leaf diseases (follow label rates) as soon as symptoms first appear to stop spread.
How often should I water Lactuca sativa during the main growth phase to avoid bitterness or bolting?
During the ~50-day growth period, keep the soil consistently evenly moist (not soggy) so lettuce doesn’t stress—aim for watering when the top 1 inch of soil starts to dry. In warm part-sun conditions, this often means about 1–2 waterings per week, but adjust to rainfall and your soil; sandy soils dry faster. Avoid letting plants swing between dry and wet, which can drive bitterness and speed up bolting.
When is Sanguine Améliorée ready to harvest, and how do I tell?
Harvest around 50 days from sowing when heads are firm (or for leaf types, when outer leaves are fully expanded and crisp). Look for leaves that reach their full size and have strong color, with minimal inner stretching; if the center starts to elongate, quality drops. For best flavor, cut early in the day and harvest before the plant bolts (flower stalk begins to form).

Sanguine Améliorée unfolds with a lush, butter-soft heart and a striking sanguine blush—crisp at the edges, tender through the center, and richly fresh in every leaf. Expect a slow, steady build to a full, rounded head in about 50 days, with velvety texture that invites gentle handling and rewards with a mild, sweet flavor. Ideal for fresh salads and elegant leaf-forward platters, its color makes every bowl look garden-made and abundant.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 35°F before moving outdoors. Harden off for 6 days first.

Expert Note

For best sweet flavor, keep lettuce cool and avoid transplanting into weather that’s consistently warm or dry; shade during heat spikes helps prevent bitterness.
