Organic 'Truchas' red mini-romaine lettuce
Lactuca sativa
Product code : BIOVO-0047
'Truchas' is a Little Gem-type mini-romaine producing a small dense upright crisp head. Dark cherry-red outer leaves contrast with a bright-green heart. Maturity is approximately 45 days. The variety has high resistance to downy mildew races 29–41 EU and 7–10 US plus TBSV, and intermediate resistance to lettuce mosaic virus race 1. Sow small batches every two or three weeks to spread harvest. Spacing of 15–20 cm supports complete mini heads, while steady moisture and light summer shade preserve texture. Harvest early in the morning and chill promptly. Documented resistance never replaces rotation, airflow, or careful watering. Its compact habit fits small plots and balcony containers especially well.

Botanical nameLactuca sativa
Organic 'Truchas' red mini-romaine lettuce (Lactuca sativa) 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. Its individual size also makes every mini head easy to present whole, halved, or quartered for quick everyday meals.
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. Water transplants immediately and apply light mulch once the soil has warmed to moderate sudden moisture changes around shallow roots.
Maturity is generally reached in approximately 45 days. Harvest once the mini head is firm compact and well coloured before the heart begins elongating. The variety has 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. Harvest early in the morning, wash between leaves, and chill mini heads promptly in a clean container. Inspect the heart before storage and remove every damaged outer leaf.

Growing method
Growing 'Truchas' lettuce from seed. Sow on fine moist soil and cover only 0.3–0.5 cm. Sow 'Truchas' in cool, finely prepared soil and keep the shallow seed zone evenly moist. Choose a position for 'Truchas' with full sun to partial shade without sacrificing airflow or watering access. Provide immediate light after emergence so the young rosettes remain compact. The spacing guidance for the planting is thin to approximately 15 to 20 cm (6 to 8 in), with 25 to 30 cm (10 to 12 in) between rows; use it when balancing airflow with the available growing area. Thin or transplant gently to preserve airflow around the developing small upright compact dense uniform head. The rosette produces the expected harvest form: dark cherry-red outer leaves and green heart with tender crisp ribs. Protect the developing crop from soil splash and rough handling. Harden indoor starts gradually and protect them from severe frost or drying wind. Because its habit is small upright compact dense uniform head, this lettuce needs enough room for routine care and neighbouring plants. Water at soil level before the shallow root zone dries deeply, but do not leave it saturated. Harvest after dew dries, shade the leaves promptly, and remove bolting plants before the next succession. Harvest the crop at the leaf, rosette, or head stage described for the product. Cut with a clean tool after dew dries, shade the harvest immediately, and remove bolting or diseased plants before they affect the next succession.

Watering
'Truchas' red mini-romaine lettuce has a compact, shallow root system, so keep the soil evenly moist while its dark cherry-red outer leaves and green heart with tender crisp ribs develop. Water 'Truchas' red mini-romaine lettuce gently at soil level, let the surface begin drying before the next irrigation, and never leave its crown in standing water. Direct 'Truchas' red mini-romaine lettuce's water beside the rosette so it does not remain trapped in the forming head. Check container-grown 'Truchas' red mini-romaine lettuce daily in warm wind, but empty its saucer promptly.
Soil type
Prepare loose fine fertile soil enriched with mature compost, able to retain steady moisture without becoming waterlogged. Shallow lettuce roots need an aerated zone; crusted compact or very sandy soil quickly slows growth and makes leaves more bitter. Aim for approximately pH 6.0–7.0. Incorporate organic matter before sowing rather than placing fresh manure near leaves. Improve drainage in heavy soil, avoid beds recently occupied by diseased lettuce, and rotate with unrelated crops.
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 mini-head harvest.
Moisture
Evenly moist soil without saturation
Seasonal care
Seasonal care for 'Truchas' lettuce. Use two cool-weather opportunities: sow once when spring soil is workable and again only after late-summer heat begins to ease for an autumn crop. Cover seed by roughly 0.3 to 0.5 cm and keep the medium near 10 to 20 °C (50 to 68 °F); emergence normally takes 5 to 10 days, while warmer soil can sharply reduce it. Keep the surface evenly moist, then thin promptly so each compact head has light, air, and an unobstructed crown. Water at soil level in the morning, avoiding both a dry crust and standing moisture inside the developing crown. 'Truchas' red mini-romaine lettuce container guidance: at least 20 to 25 cm (8 to 10 in) deep and approximately 3 to 5 L per mini head. Set the pot where runoff can escape and light is adequate. During warm weather, afternoon shade and renewed sowings can preserve leaf quality, but no placement prevents bolting indefinitely. Check for slugs, chewing insects, and damaged outer leaves, using barriers and sanitation before considering any treatment on an edible crop. Follow the supplied harvest cue—approximately 45 days—then cut while leaves are crisp and before the centre elongates or flavour turns strongly bitter. For an autumn crop, sow only when local summer heat is easing and enough growing time remains before persistent freeze. Remove bolted or diseased plants promptly, chill sound leaves after harvest, and leave the bed clean for the next succession.

Growing 'Truchas' lettuce in containers. For 'Truchas', choose a container matching this guide: at least 20 to 25 cm (8 to 10 in) deep and approximately 3 to 5 L per mini head. Keep several drainage holes unobstructed. Leave enough rim space for slow watering without splashing soil into the dark cherry-red outer leaves and green heart with tender crisp ribs. Plan around the way 'Truchas' grows: small upright compact dense uniform head. Keep access to the root zone for watering and inspection. Check the shallow root zone often and water before it dries deeply, always emptying the saucer. Leave enough access around the crop to inspect and cleanly harvest harvestable leaves. Sow this lettuce thinly or transplant a sturdy seedling without burying the crown. Lay out the rosette at thin to approximately 15 to 20 cm (6 to 8 in), with 25 to 30 cm (10 to 12 in) between rows, then keep paths open instead of filling gaps with another mature crop. Place the container in sun during cool weather and use light afternoon shade as heat increases. The planting needs full sun to partial shade; nearby walls or taller crops should not compromise it. Harvest clean outer leaves while preserving the centre, or cut the whole plant at its intended stage with a clean knife. Cut clean leaves before bolting, cool them promptly, and remove diseased potting debris from reuse. Succession-sow another labelled container instead of keeping bolting this lettuce. Remove diseased mix from reuse, wash the pot, and cool every edible harvest promptly.

Bloom period
When heat, long days, or stress triggers bolting, the plant rapidly elongates a branched stalk bearing small yellow flowers. This occurs during the first season and marks the end of the best leaf quality. Harvest once the centre stretches to avoid bitter tough foliage, or allow only one healthy plant to bloom where seed dispersal will not cause a problem.
Fruiting
After flowering, small dry beaked fruits with a tuft may form and release seed. This stage is not desired for leaf harvest because the plant becomes bitter and directs energy toward reproduction. Cut the stalk before dispersal to limit volunteer seedlings, or allow only one healthy plant to dry when seed saving is clearly permitted and identified. Keep seed separate from lettuce intended for food.
Days to maturity
Approximately 45 days
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.
Garden associations
In goodcompany.
Companion plants
Radishes, green onions, and low herbs may temporarily occupy spaces between young lettuce plants when harvested before mini heads reach full width. A pea trellis positioned at a distance may provide light afternoon shade without blocking airflow. These combinations mainly organize space and guarantee no protection from pests or disease. Avoid root competition and remove companions that dry the soil, constantly touch leaves, or make harvest difficult. Rotate the bed afterward with an unrelated family and keep diseased residue away from healthy plants.

'Truchas' lettuce in the kitchen. Grilled 'Truchas' mini-romaine — Remove damaged outer leaves from four compact heads, rinse between the leaves, and dry thoroughly. Halve each head lengthwise through the base so it stays together. Whisk 20 mL olive oil with 10 mL red-wine vinegar, 5 mL Dijon mustard, and black pepper. Brush the cut faces lightly and grill over medium-high heat for 60–90 seconds, just until marked and warmed. Transfer to a clean platter while the ribs remain crisp. Spoon over the remaining dressing and add sliced pear, toasted walnuts, and cooked lentils or crumbled cheese. Finish with a small pinch of salt and serve immediately. The red leaves are attractive when lightly charred, but prolonged heat will make them limp and dull. Keep washed lettuce away from raw meat and muddy produce, and never reuse a contaminated plate after grilling. Discard slimy or rotten leaves. Refrigerate unused heads clean, dry, and whole; store toppings separately because the assembled warm salad quickly loses its intended texture.
Frequently asked questions
Your questions,answered.
Is 'Truchas' romaine or Little Gem?
Both descriptions are compatible. It belongs to the Little Gem type, commonly marketed as mini-romaine in North America. It forms a small upright head with crisp ribs and a dense heart rather than one large elongated romaine. Size permits 15–20 cm spacing and whole-head harvest in one or two servings. Do not confuse it with open red leaf lettuce because it should form a compact heart. Harvest early in the morning, keep the head shaded, and chill it promptly. Wash carefully between leaves before serving and discard every slimy, mouldy, or abnormal-smelling portion. Preserve the compact heart until preparation. Serve promptly after washing.
When should a 'Truchas' mini head be harvested?
Begin checking at approximately 40 days and generally harvest around 45 days. The head should be full upright firm and well coloured with a tight but not hard green heart. Harvest earlier in warm weather if the centre begins elongating. Cut early in the morning and chill immediately. For repeated leaves, remove only the outermost, although the best presentation comes from one complete mini head cut at the base. After cutting, wash between leaves, dry them, and refrigerate without delay. Do not leave one mature mini head in the garden for several days when heat is forecast because its texture may deteriorate quickly. Inspect each successive batch regularly.
What do 'Truchas' resistances mean?
The variety has high resistance to Bremia lactucae downy mildew races 29–41 EU and 7–10 US plus lettuce necrotic stunt associated with TBSV, and intermediate resistance to lettuce mosaic virus race 1. High or intermediate resistance is not immunity, and unlisted races may remain problematic. Provide airflow, avoid prolonged wet foliage, remove severely affected plants, and rotate crops. Water near the soil to limit splashing, provide enough spacing, and clean tools before moving from an affected area to a healthy one. Continue inspecting each succession because other diseases and races may still appear when conditions favour them. Documented resistance does not cover every pathogen.
How can poor summer germination be avoided?
Sow early in the morning into pre-moistened soil and lightly shade the bed until emergence. Lettuce seed needs light and germinates poorly when buried deeply or when soil remains very warm. Cover only a few millimetres, keep the surface moist with fine watering, and move containers into a cooler place. Seed may also be started indoors in a cool room, then seedlings gradually hardened before transplanting. Label the date, increase airflow once seedlings appear, and transplant before roots become tightly crowded. Use clean mix and a draining container, keeping the crown above soil level. Continue with gentle watering after emergence and avoid sudden drying.
Can 'Truchas' be grown in a container?
Yes. Use a well-drained pot or box at least 20–25 cm deep and allow approximately 15–20 cm per mature mini head. Rich but light potting mix limits waterlogging and remains easy to irrigate. Place the container in sun during cool weather, then light partial shade during strong heat. Check moisture daily because shallow roots dry quickly. For a compact head, keep one plant per usable space and hold the crown above the mix. Harvest the whole mini head when firm and well coloured, before the centre elongates, and chill it promptly. A second sowing started two or three weeks later can replace the harvested plant.
Wildlife and pets
Life,around your plants.
Supporting wildlife
Lettuce allowed to bolt develops a branched stalk with small yellow flowers that various insects may visit. Flowering is undesirable for leaf harvest, however, and no pollinator is required. Harvest the mini head as soon as the centre elongates, or allow only one healthy plant to bloom where volunteer seedlings will not cause a problem.
