Organic ‘Truchas’ red mini-romaine lettuce (Lactuca sativa ‘Truchas’) is a compact Little Gem type combining dark cherry-red outer leaves with a bright-green heart. The small upright head remains dense, well proportioned, and easy to serve whole or in wedges. Thick crisp leaves have tender ribs and mild flavour. Contrasting colour adds ornamental value to the garden and pairs especially well with green mini-romaine in salads, sandwiches, wraps, and fresh platters.

Direct-sow as soon as soil can be worked or start plants three to four weeks before transplanting. Barely cover seed and keep cool because germination drops in overly warm soil. Space plants 15–20 cm apart for complete mini heads or sow more densely for baby leaves. Choose loose fertile soil enriched with mature compost, moisture-retentive, and well drained. Grow in sun during cool weather; light afternoon shade and steady watering preserve quality through summer.

Seed catalogues generally list approximately 45 days to maturity. Harvest once the mini head is firm compact and well coloured before the heart begins elongating. Enza Zaden documents high resistance to Bremia lactucae downy mildew races 29–41 EU and 7–10 US plus lettuce necrotic stunt caused by TBSV, and intermediate resistance to lettuce mosaic virus race 1. These levels are not immunity; maintain rotation, airflow, and hygiene.

Planting guide

From planting to establishment.

Planting depth Barely covered, approximately 0.3 to 0.5 cm (1/8 to 1/4 in)
Spacing / density Thin to approximately 10 to 15 cm (4 to 6 in), with 30 to 45 cm (12 to 18 in) between rows
Establishment temperature 10 to 20 °C (50 to 68 °F)
Establishment time Approximately 7 to 10 days
Best planting time April to August
Propagation Direct sowing or indoor sowing three to four weeks before transplanting
Growing method
Direct sow outdoors or in containers from April through August for continuous harvests. Cover the seeds lightly and keep the soil consistently moist until germination. Grow in full sun during spring and provide partial shade during the hottest part of summer. Thin seedlings to encourage uniform growth and healthy heads. Maintain rich, cool, well-drained soil throughout the season. Harvest outer leaves as needed or cut the entire head once mature.

Soil and care

The right conditions.

Exposure Full sun to light partial shade
Soil pH Approximately 6.0 to 6.8
Minimum temperature -2°C (28°F)
Watering
Keep the surface consistently moist during germination with a very gentle stream so barely covered seeds are not displaced. Once established, water deeply as soon as the top one or two centimetres begin to dry. Shallow roots poorly tolerate cycles of drought and excess water; this stress encourages bitterness, tipburn, and bolting. Water early in the morning at soil level or by drip, avoid splashing soil onto leaves, and apply light mulch after thinning. Check containers daily in hot or windy weather.
Soil type
Rich, cool, well-drained soil with plenty of organic matter. Fertile soil encourages vigorous growth and intense foliage color.
Fertilization
Incorporate mature compost before sowing and correct fertility according to a soil test or label directions. Lettuce requires moderate steady nutrition; one light balanced feed at planting is generally sufficient in fertile soil. If foliage pales after thinning, side-dress one small nitrogen dose and water. Avoid heavy or late applications that create soft tissue, increase some disorders, and make harvested produce harder to cool. Never apply granular fertilizer onto leaves and stop feeding shortly before whole-rosette harvest.
Seasonal care
Make successive sowings from spring through late summer for continuous harvests. Water regularly to keep the soil cool and reduce bolting. Weed lightly around the plants to minimize competition. Harvest outer leaves as needed or entire heads once mature. Apply a light mulch during hot weather to conserve soil moisture.

Container growing

Harvest
Begin checking at approximately 40 days and generally harvest around 45 days once the mini head is full firm compact and well coloured. Cut at soil level early in the morning with a clean knife, retain a few intact wrapper leaves, and chill immediately. For progressive harvest, take only one or two outer leaves and leave the heart. Wash just before use and refrigerate in a perforated bag. Harvest promptly if the centre elongates, the head loosens, or flavour becomes bitter.
