Lettuce 'Du Bon Jardinier' belongs to Lactuca sativa. Butterhead lettuce. Can grow very large. Pale green leaves with a slight red tinge. Slow to bolt. Great resistance to heat and cold. An old variety from the Rhineland (western Germany), also called Rhénania. These characteristics help you choose its position in the garden and compare this selection with other cultivars in the same group. Plan its location around its growth, leaving enough room to observe and care for the plant. The sowing date, available light and warmth received then influence the pace of growth in Quebec.

Full sun or partial shade. Prepare a growing area with soil that allows excess water to drain away freely. Direct sow starting 6 weeks before the last frost date. Sow the seeds at a depth of 6 mm (0.2 in). Leave 30 cm (11.8 in) between plants. In Quebec, choose the sowing date according to soil conditions and local frost risks rather than using one date for the whole province. Prepare a fine soil surface and maintain consistent moisture until emergence without allowing water to stand. After germination, thin as needed to give young plants the intended spacing in the row.

For leafy vegetables, match picking to the plant's habit: outer leaves, young shoots or the whole plant, depending on the type grown. Use a clean tool and preserve the centre if you want to continue harvesting. Monitor the texture of the foliage and watch for the first signs of bolting, especially during hot days. Regular watering and cool soil help you monitor growth more effectively. Prepare picked leaves promptly and discard those that are badly damaged. Staggered sowings can spread out the harvest when the season and the variety's specific instructions allow. Keep these vegetable seeds dry until the next sowing.

Growing method

Lettuce 'Du Bon Jardinier'. Before opening the packet, prepare the seed-starting supplies and this crop's future growing site. A clean surface, suitable soil and a label prevent unnecessary handling once the seeds are in place. Keep the packet dry so that the instructions specific to the seed lot remain available. Butterhead lettuce. Can grow very large. Its pale green leaves are lightly tinged with red and have good flavour. Slow to bolt. Great resistance to heat and cold. An old variety from the Rhineland (western Germany), also called Rhénania. Choose a location in full sun or partial shade. Prepare a growing area with soil that allows excess water to drain away freely. Plan to sow directly starting 6 weeks before the last frost date. The stated sowing depth is 6 mm (0.2 in). Allow a spacing of 30 cm (11.8 in) between plants. Leafy vegetables benefit from sowing in well-prepared soil kept consistently moist. Dense emergence requires thinning to give leaves room to develop. Cool temperatures suit several of these crops, while prolonged heat can speed up bolting. Adjust sowing to the production season specific to the chosen vegetable.

Watering

Lettuce 'Du Bon Jardinier'. Check moisture in the root zone before deciding whether to water. Rainfall, wind conditions and the exposure of the container all influence how frequently you need to provide water. Prepare a growing area with soil that allows excess water to drain away freely. Leaves stay more tender when the plant receives consistent moisture. Water gently at soil level, adjusting the frequency for rainfall and heat. Germination requires particular attention if the surface dries quickly.

Soil type

Lettuce 'Du Bon Jardinier'. The soil must allow roots to receive water and then let excess water drain away. Prepare the soil without working it when it is waterlogged, and address compaction or standing water first. Prepare a growing area with soil that allows excess water to drain away freely. Leaves stay more tender when the plant receives consistent moisture. Water gently at soil level, adjusting the frequency for rainfall and heat. Germination requires particular attention if the surface dries quickly.

Fertilization

Lettuce 'Du Bon Jardinier'. Adjust feeding to the actual fertility of the soil or the nutrients already in the growing mix. Soil that is already fertile does not automatically require another application. Follow the chosen fertilizer's instructions, and avoid feeding more when roots are struggling with poor drainage. Prepare a growing area with soil that allows excess water to drain away freely. Leaves stay more tender when the plant receives consistent moisture. Water gently at soil level, adjusting the frequency for rainfall and heat.

Seasonal care

Lettuce 'Du Bon Jardinier'. Early in the growing period, check emergence and the condition of young roots before changing care. Carry out thinning, transplanting and the installation of supports while the plants are still at a stage that allows careful handling. Throughout the growing season, observe the plant after rainfall, during windy periods and following episodes of hot weather. Remove genuinely diseased parts and keep tools clean. At the end of the growing period, sort the debris, clean containers and store remaining seeds in a dry place. Butterhead lettuce. Can grow very large.

Growing in containers

Container growing

Lettuce 'Du Bon Jardinier'. When growing in a container, consider the available root space, the drainage and the access to light as a whole. Choose a stable pot with clear drainage holes and a growing mix intended for containers. A decorative planter without a drainage outlet should hold an inner pot with drainage holes. Keep the container accessible so that you can check the growing medium rather than watering without inspection. Butterhead lettuce. Can grow very large. Its pale green leaves are lightly tinged with red and have good flavour. Slow to bolt. Great resistance to heat and cold. An old variety from the Rhineland (western Germany), also called Rhénania. Choose a location in full sun or partial shade. Prepare a growing area with soil that allows excess water to drain away freely. Plan to sow directly starting 6 weeks before the last frost date. The stated sowing depth is 6 mm (0.2 in). Allow a spacing of 30 cm (11.8 in) between plants. Allow enough space for the foliage before adding more plants. A heading variety needs room to form its head; growing for baby leaves may require a different planting density. Keep pathways for harvesting without crushing the plants.

Harvest

The timing of the harvest varies with the weather conditions and the date on which the seeds were sown. Harvest Lettuce 'Du Bon Jardinier' when the edible parts have the size, colour or texture expected for the variety. Harvest with clean hands and use a clean tool when stems resist. Harvesting regularly often helps you enjoy a crop with more consistent quality from one picking to the next. Discard damaged parts and promptly use the most delicate harvests.

Companion plants & uses

Companion plants

Lettuce 'Du Bon Jardinier'. Here, companion plants are chosen to share a growing site and simplify care. Position tall plants where they will not deprive their neighbours of the light they need. No arrangement of companion plants can, on its own, guarantee that the crop will be protected from pests. Butterhead lettuce. Can grow very large. Its pale green leaves are lightly tinged with red and have good flavour. Slow to bolt. Great resistance to heat and cold. An old variety from the Rhineland (western Germany), also called Rhénania.

Garden use

Lettuce 'Du Bon Jardinier'. Prepare the location around the plant's mature shape and the access needed for care. Before you plant, identify the parts of the growing area that will be shaded by a fence or by other crops. An open space beside the foliage makes observation and care easier. Install watering equipment before the stems make the area difficult to reach. Butterhead lettuce. Can grow very large. Its pale green leaves are lightly tinged with red and have good flavour. Slow to bolt. Great resistance to heat and cold. An old variety from the Rhineland (western Germany), also called Rhénania. Place leafy vegetables near a frequently used pathway to pick them as needed. Curly, red or broad leaves also add visual interest to the vegetable garden. Sowing small sections prevents a large quantity from reaching the same stage all at once. Combine colours while maintaining the space and growing conditions each type needs. Allow enough space for the foliage before adding more plants. A heading variety needs room to form its head; growing for baby leaves may require a different planting density. Keep pathways for harvesting without crushing the plants.

Recipe and storage

Recipe idea

From garden to table

Lettuce 'Du Bon Jardinier'. Prepare a harvest of leaves picked at the tender stage. Remove damaged parts, wash thoroughly and drain. For lettuce, assemble a salad with a light dressing added at the last moment. For cabbage, mustard or spinach intended for cooking, cut the leaves, then wilt them in a pan with a little oil and onion. Add a small amount of water only if needed, and stop cooking at the desired texture. Thick leaf ribs can be prepared separately for more even cooking. A small plain portion lets you discover the cultivar's flavour before choosing additional seasoning. Leaves that have become tough or strongly affected by bolting will not regain their quality simply through prolonged cooking. Serve immediately or refrigerate leftovers promptly. Keep each vegetable clearly identified, because the leaves of a lettuce plant and those of a cabbage do not call for the same uses. Harvest leaves at the stage appropriate to the variety, without routinely removing the entire centre of the plant.
